List of characters in Foster's Home for Imaginary Friends
This is a list of characters seen in the American animated television series Foster's Home for Imaginary Friends.
Main characters
Blooregard Q. Kazoo
Blooregard (Bloo for short) was the first character created by McCracken, and is a five year old, two-foot tall, door-shaped, blue blob that weighs 31 pounds (when dry). He doesn't have legs, either gliding or bouncing his way around, and doesn't appear to have arms at first, but can produce them at will. He loves apple juice, and celery (as seen in "Fosters Goes to Europe") but is allergic to tomatoes (demonstrated in "One False Movie" when his movie is cut off by an special episode of Lauren Is Exploring) and flowers (seen in "Challenge of the Superfriends"). In "Bloo's Brothers," Frankie remarks upon his fondness for playing with Mac's chemistry set.
In early episodes ("House of Bloo's" in particular), he was innocuous and naive, good-natured but goofy. However, he became incorrigible and wild, perpetually scheming against Mr. Herriman and Frankie while playing pranks. He also became jealous, selfish and spoiled, with a short attention span for what he wants and a hyperactive eagerness to move on to the next "awesome" thing. Bloo's behavior is often used as a MacGuffin; for instance, in episode "Land of the Flea," Bloo shears Eduardo because he wants Eduardo's fleas - simply because Eduardo has the fleas and Bloo doesn't.
Bloo has often demonstrated a hyperly nonchalant personality. He is still incredibly naive (he has no idea what sarcasm is in episode "My So-Called Wife" even though he uses it all the time) and possesses a degree of childlike wonder (especially over something he does not have). Bloo often disregards the rules or finds loopholes in them easily, and often tells overdramatic lies to achieve means to an end. Bloo, along with Mac, are often the ones at the receiving end of the episode's morality tale, usually because Bloo's antics got them there in the first place - such as in "Sweet Stench of Success". Bloo often has a tendency to accept outrageous ideas as fact, such as in "The Big Picture", where he develops numerous conspiracy theories about an unusual picture taken before Mac and Bloo arrived at the house.
He is also able to make up such stories to explain strange occurrences - for example, when he finds the house empty in "Squeeze the Day", he decides that a meteor (the son of the one that killed the dinosaurs) killed every living person on Earth, though turning some into zombies. Blooregard can also change his voice to a character known as "Orlando Bloo", a pun on actor Orlando Bloom. All he needs is a top hat, stand on someone's shoulder and wear an overcoat and moustache. He refers to it as a trick that has never failed him, even though in fact it has never succeeded. He usually performs it with Mac but has used Wilt as his unsteady bottom, apparently upsetting Mac when he saw his imaginary friend in the top hat and moustache.
Madame Foster seems to have a fondness for Bloo whereas Mr. Herriman overtly despises him and tries to get him thrown out almost constantly - it's notable that these incidents rarely reach Madame Foster. Despite his hijinks and self-centered behavior, Bloo has managed to forge several close friendships with the other imaginary friends in the house and is often allies with Frankie against Mr. Herriman. However, many of the other imaginary friends continue to note the various incidents he has caused. Keith Ferguson is the voice of Bloo.
Coco
Dreamed up by a young girl who was stranded on a desert island, Coco is a sanity-challenged imaginary friend. Ever since leaving her creator, she has seemingly gone slowly insane, as illustrated through "My So-Called Wife". She was apparently studied by scientists before coming to Foster's, which likely contributed to her insanity. The hour-long episode "Good Wilt Hunting" will explore this aspect of her past. She has the head and neck of a palm tree, the body of an airplane, the beak of a bird, and human legs and feet. Because of that, she has been called a "bird, airplane, plant-thing" by some of the residents. Despite being part bird and plane, we learn in "Foster's Goes to Europe" that she's afraid of flying.
On Blooregard Q. Kazoo, the official blog for the show, Craig McCracken explains Coco's design. [1]
"The idea behind Coco is that she was created by a lonely kid trapped on a desert island. Her design elements are made up of the kids thoughts/surroundings. Her tree head = the palm trees on the island, Her airplane body=the dream of being rescued and nightmare of how the kid ended up on the island, Her red beak=the deflated rubber raft that brought the kid to the island, Her shoeless sunburned feet=all the kid stares at all day, and her name Coco= Coconuts, what the kid lived on. As you can tell I think too much about this stuff."
Her only verbal utterances and written means of communication is "coco" (with each syllable pronounced "co"), which most of the imaginary friends, Mac, Frankie, and Madame Foster can understand. This can lead to strange conversation, such as in "House Of Bloo's", when Bloo repeatedly said yes every time Coco said "coco?", until Wilt explained that that's all she ever says. When Bloo asked what she was really asking them, Wilt replied "You want any juice?" She also has had to be heard by many people in "Hiccy Burp" (taking over for Wilt as the talent show pagent's host) and in "Cuckoo For Coco Cards" as she led Mac's classmates on a tour of the home. She usually is understandable to all, but may not be, depending on what jokes are needed. She also seems unable to write anything but "Co Co Co," with similar rules applying to whether or not people can read it (Mr. Herriman once read a ransom note from her in "Crime After Crime", but was unable to figure out who sent it despite the obvious clue, while Mac read her diary, unable to decipher it in "Squeeze The Day"). In the episode The Big Picture, one of the clues Bloo thought to why all the imanginary friends disappeared was when Coco actually said something besides "Coco," which caused everyone to run off ("Cheese.").
When she is excited, scared, or needs the attention of others, she has the ability to lay plastic Easter eggs, similar to those found in arcades, that can contain anything from Ming vases to tickets for redemption of prizes to money or even auto parts, but in the aforementioned "Cuckoo for Coco Cards", she made trading cards inside the eggs, and later bobble bodies. Often, these seem to fulfill whatever need the person opening them has at the time, though she won't take requests, as seen in "Camp Keep A Good Mac Down," when she creates many canned foods for dinner, but no can opener when asked. She also had a love affair with a floor lamp during "Partying Is Such Sweet Soireé", took three jobs — a fast-food employee, a mall courtesy desk clerk, and a security guard, all in the same day — to pay for a massage chair for Madame Foster's birthday gift in "Store Wars" and also reportedly has a vacation home away from Foster's, having to pay for that in "A Lost Claus" by playing a Mall Santa, much to the disbelief of Mac, who accidentally exposes her, getting her fired, which was settled out of court after her wrongful termination suit was filed. Candi Milo provides the voice of Coco.
Duchess
Called Duchess for short, this imaginary friend is a scheming, arrogant Picasso-like pain in the neck, who is actually two-dimensional when she turns in certain directions. She's considered a "high-maintenance" friend, not wanting to do anything for herself, and is so lazy that she needs somebody to open her eyelids when she wakes up.
In the pilot, she and Terrence conspire to get rid of Bloo after a spoiled, bratty daughter wants him (and, in the process, rename him "Tiffany") instead of Duchess, who was chosen by her mom and dad. As punishment for trying to get rid of Bloo, she has to stay at the house and is no longer eligible for adoption. She has no liking for unauthorized parties as shown during "Partying Is Such Sweet Soireé" because it disturbs her twenty-three hours of beauty sleep (and Bloo would like to see her make it twenty-four). During that party, she tried to bribe a sugar-crazed Mac into calling Madame Foster by offering Mac "stupid gourmet chocolates."
Despite supposedly being uneligible for adoption, she was adopted by the Applebee family in "Duchess of Wails", and needless to say, she was not happy about it. Neither was Mac, who lives next door to the Applebees. The noise almost drove Mac's mother to move, which Terrence used to scare Mac into thinking that they'd be moving to Singapore (in Wisconson). Mac and Bloo returned her to Foster's to prevent this, after an unsuccessful attempt to sabotage everything in the Applebee's apartment in an attempt to have them do it for them. In "The Big Picture", she gave Eduardo an "extreme makeover" that made Eduardo look more like Duchess. Grey DeLisle provides Duchess' voice.
Eduardo
Eduardo is a seven-foot tall (to his horns), 542-pound "protector friend" and is as gentle as anyone in the house, despite his menacing appearance. He resembles a mixture of a minotaur and the creatures from Maurice Sendak's Where The Wild Things Are, with his purple fur, horns, fangs and skull-shaped belt buckle. He commonly speaks "Spanglish". Despite being a protector friend, he's something of a coward, as noted in "House Of Bloo's" by Wilt that he wouldn't hurt a fly, because, as Eduardo pointed out, he's too scared of them. During "Cuckoo for Coco Cards," on Coco's imaginary friend trading cards, Eduardo is classified first as "a big fat baby" (offending Big Baby) then a "chicken," then a "scaredy cat," before being finally upgraded to "crazy idiot" after much trying. He has shown great strength when he is frightened too much, often involuntarily injuring whoever or whatever is scaring him. This caused him to be a favorite contender in an immaginary friend fighting contest (he would get scared and end up throwing the opponent out of the ring). It has also been implied that he can be quite intimidating when he is angered (usually by someone doing something bad to one of his friends). He also nutured an pink elephant squeak toy like a baby in "Squeakerboxxx," even going as far to name it Paco.
His favorite food is potatoes and he was imagined up by a young girl who lived in a tough neighborhood before coming to Foster's, who will be seen in the hour-long episode "Good Wilt Hunting". During "Who Let The Dogs In?", he is shown to be fond of dogs (particularly puppies) and has a collecton of beanie buddies (a parody of Beanie Babies). He allegedly has the brain of a four-year old, best demonstrated in "Bye-Bye Nerdy" when Bloo asked him which way is up, to which he responds "I don't know." In "One False Movie", we learn that one of his favorite TV shows is Lauren Is Exploring, an obvious spoof of Dora The Explorer. Tom Kenny voices Eduardo.
- In the Latin American dub of the series, Eduardo speaks with an over-exaggerated American accent.

Frances "Frankie" Foster
Frankie is the easy-going, 22-year-old granddaughter of Madame Foster who is in charge of everything at Foster's (once referred by Mac as "the estate manager"), from cooking to cleaning the house to doing the laundry. She occasionally feels stressed out from everything, letting Mr. Herriman get under her skin more often than not for sticking to his rules. We also learn that she's into punk rock, as discovered in "Everyone Knows It's Bendy".
She can be quite charming, though, as seen in "Frankie My Dear", where Mac, Bloo, an imaginary Prince Charming, and a pizza delivery boy named Chris all fall briefly in love with her. Frankie can be skeptical at times, as seen in "Imposter's Home For Um…Make 'Em Up Pals", where she thinks Goofball John McGee isn't an imaginary friend because of his overly-human appearance. In fact, Goofball has an elephantine trunk hidden behind a red clown nose he had been wearing at the time. She also has an unhealthy addiction to Madame Foster's home-baked cookies, often driving her into a frenzy.
It's not a good idea to get on her bad side, as she gave Mr. Herriman all sorts of fits throughout "Busted", where she had to clean up various messes made when Mac and friends were trying to repair Madame Foster's bust, or in "Crime After Crime", where she tried making "It" (a smelly, stinky food concoction that Bloo likened to vomit) many times, only to have ceiling plaster fall in, which made Madame Foster smack her hand and tell her to make it again. When she finally manages to make the dish, Bloo is the only one left to eat it. Throughout the episode, Mr. Herriman had punished everyone but Bloo with no supper during an extended attempt to dispose of his hidden carrots. Ironically, Bloo was the only one actually doing anything wrong, having seen "It" earlier on and doing everything he could to get out of supper. The others simply saw his carrots or were near his hiding places. Bloo ended up having to eat the entire meal by himself as punishment for all his earlier pranks, much to his regret and disgust. She also won the election for president of the house in "Setting A President", but resigned when she found out the pay was worse than her old job. In the cold, dark autumn of 1984, Frankie was the first one to open the secret door containing the Scribbles, until Bloo accidently released them in "The Trouble with Scribbles". Grey DeLisle provide's Frankie's voice.
- Frankie is named after musician Frank Black, the character's look loosely based on series supervising producer (and real-life spouse of series creator Craig McCracken) Lauren Faust. She always wears a stylized Powerpuff Girls T-shirt complete with versions of Buttercup (in green), Blossom (in pink) and Bubbles (in light blue) most of the time

Mac
Mac is a smart, square-headed, precocious, eight-year-old boy who created Blooregard Q. Kazoo when he was three years old. Mac is unusually smart for his age, with a sense of reason and somewhat large vocabulary to match. He tends to be the one to settle any mishaps that the imaginary friends (particularly Bloo) end up causing. Even though they argue, Mac and Bloo are best friends. Mac often functions as Bloo's conscience, since Bloo's freewheeling egotism often gets him into trouble, even though in several episodes, Bloo acts as the conscience and Mac has been a troublemaker. McCracken states that "Mac is a more like me now: aware of others' feelings, quiet, shy, sensitive. Mac also seems to look more like me as a little kid, which was unintentional, but it just happened that way."
Away from the house, he lives in an apartment with his mother and his older brother, the bothersome bully Terrence. Mac isn't very popular at his school, as shown in "Bye Bye Nerdy", where Bloo tries to make him cool, but ends up embarassing him in front of the whole city, and the outset of "Hiccy Burp", where he is insensed about Richie Wilderbrat and his friend, Blake Superior. This may be related to his grumpiness, which as shown in "Go Goo Go" had him originally disliking Goo from seeing little worthwhile about her, although he completely befriends her when he realizes that she is nice. He also has a condition in which he gets hyperactive after eating only a small bit of sugar, as seen in "Partying is Such Sweet Soireé" ( even though in another episode, Mac is seen raiding the refridgerator with Bloo, he eats a number of sugary foods, and doesn't go hyperactive). Sean Marquette voices Mac.
Madame Foster
Martha Foster founded the home that bears her name. She's had a strange life, having once gotten lost in the labyrinthine house for three days, eating nothing but acorns and toothpaste. She also spent forty-six days in the horse stables when her granddaughter accidentally let the Scribbles out from the forbidden door in the cold autumn of 1984. She also owns what looks like a late 1970's Pontiac Firebird sports car complete with the bird on the hood similar to the one shown in the Smokey and the Bandit movies, which she likes to drive around town.
Kooky and charming, and always wearing a smile for anyone to cheer them up as their surrogate grandmother, she's a fun-loving old woman who always finds a way to have a good time, even if she has to break Mr. Herriman's rules in order to do so, she is truly a kid at heart.. Mr. Herriman is never happy about this, but since it was Madame Foster who created him in the first place, he doesn't have much of a say about it. She often pokes good-hearted fun at others, like in "Mac Daddy" where she punned Mac and Cheese (referring to the popular pasta dinner maccaroni and cheese) and "Bloo Cheese" (a type of cheese). She is quite sneaky and malicious when she needs to be, as seen in "Foster's Goes to Europe" when she purloined Mac's tickets to Europe with a rather long hug. She then went on vacation with her friends and a homesick imaginary friend named Eurotrish. She even bought the stuff Mac put up for auction on an internet auction web site in "One False Movie", not knowing that she was buying her own stuff or funding much of the movie that Mac and Blooregard were making.
However, she sometimes makes rude jokes out of someone's unfortunate situations (most notably while Bloo was eating a horrible meal Frankie specially prepared) with a below-basic level of sarcasm. Madame Foster and Mac seem to be kindred spirits, as she has never gotten rid of her imaginary friend (Mr. Herriman) and Mac refuses to give up Bloo. Sometimes, Madame Foster's daily actions tend to change from morally good to psychotic (such as running with pointy objects inside the mansion, using exaggerated methods to solve many problems, or even performing semi-nudism), but most characters also suffer from her same personallity disorder (Mr. Herriman for example: he always acts as a cultured refined imaginary friend, but in some critical cases he can go through spasms). Candi Milo provides her voice.
Mr. Herriman
Mr. Herriman (also known as "Funny Bunny" or "Mr. H." for short) is an anthropomorphic rabbit (like Harvey) who wears a top hat, a monocle, a vest, and a mustache while speaking in a British accent in a personification of the Edwardian era). He is the president of the house (or as Mac called him, "the head of business affairs" in "Cuckoo for Coco Cards") that he runs for Madame Foster, who created him, thus making him the oldest friend in the house, which is something he is quite sensitive about.
Mr. Herriman is a stickler for rules, having made many silly and impractical rules in an attempt to keep everything running smoothly, and is also an inviting target of jokes around the house by the others, especially in "World Wide Wabbit", when Bloo and Mac accidentally shoot a video of him performing for his creator, which Frankie and the others had a hard time believing. He usually refers to characters in a very "proper" manner - for example, calling Bloo "Master Blooregard" or Frankie "Miss Frances;" he has on occasion dropped this during points of stress, saying simply "Coco" once and another time "Master Bloo." In many episodes, we have seen that he has a disdain for Bloo, often wishing that he would be adopted. In "Camp Keep A Good Mac Down", he had to go back to his primitive state while suffering from hunger, until Frankie pages him with a phone call after he befriended some smaller rabbits who gave him a carrot, which was later illustrated in "Crime After Crime", as he is shown to have an addiction to carrots (which he will go to great, even desperate, lengths to hide), despite his best attempts to ignore or get over it. When he lost the election in "Setting A President", he was forced to work as a grocery bagger, and when Frankie felt sorry for him (and saw how little the presidential job paid), Frankie resigned and gave the job back to him, telling him that he "deserves every penny of it". Herriman is surprisingly old fashioned, even believing that the internet is an actual net. It is believed that Madame Foster created him during the 1930's, making him believe the 2000's are still full of "pick-up" telephones. His voice is provided by Tom Kane.
- Mr. Herriman is named for Krazy Kat creator George Herriman, with a pun on "hare."
- Mr. Herriman and the Mayor of Townsville in The Powerpuff Girls have several similarities:
- They both wear black top hats and waistcoats.
- They both have a monocles over their left eye, although it has become a running joke in Foster's that Mr. Herriman's monocle has been switched between his left and right eye often many times, such as in "Hiccy Burp", where it changes three times in one scene alone. He does, however, seem not to be able to see very well without it.
- They have thinning white hair just above their temples.
Terrence
Terrence is a typical thirteen-year-old bully, with much of that bullying often directed at his younger sibling, Mac. He has a mullet haircut, a case of bad acne on his face, wears a grunge style of plaid wool shirt, and is considered to have the intelligence of a wet match in a damp cave as seen during "Seeing Red", in which he imagines up a red block ("Redd") he wanted to call "Green," only for it to end up with the exact opposite personality of his. In spite of his bullying attitude, he was seen watching a soap opera (The Loved and the Loveless) in "Berry Scary."
In the pilot, he conspires with Duchess to get rid of Bloo permanently, but fails and is punished with cleaning out the imaginary horse stables, where he was attacked by the unicorns, whom he had called "girly" earlier in the episode. In "Eddie Monster", he befriends Eduardo in a dumpster in the slums of the city and recruits him to fight in the Extremeasaur Battle circut, but is caught when he brags to Mac about it, and in "Duchess of Wails", he tells Mac that because their next-door neighbors, the Applebees, have adopted Duchess, much to their chagrin, they plan to move to Singapore, which he mistakenly believes to be in Wisconsin (which Bloo also thought). Tara Strong voices Terrence.
Wilt
Wilt was imagined by a basketball fan, getting his name from the legendary center Wilt Chamberlain. He wears old school styled basketball sneakers which makes his footsteps squeak like on a basketball court when he walks around, a red, white and blue sweatband on his wrist and the number one on his chest like a basketball jersey. He has only his right arm to use as his left arm is a stump.
The tallest of the imaginary friends at eight feet tall and 165 pounds, his eyes are on stalks protruding from his head, the left one being a bit wonky and likely blind. He prides himself on finding abandoned imaginary friends, making him a "helper friend," and is gentle to a fault, sometimes apologizing a lot; he just can't say no when someone asks him to do something, even if it's incredibly inconvenient,for example, in Where There's A Wilt, There's A Way, in which he missed the entire basketball game doing favors for everybody he saw. Bloo's lazyness sometimes makes him take advantage of Wilt's niceness by pretending to be sad or hurt.In "Partying Is Such Sweet Soireé", we also learn that he's an excellent dancer, but tends to get nervous in front of large gatherings as seen at the County Imaginary Friends Talent Show Pagent in "Hiccy Burp", resulting in him flubbing his lines. Wilt also hosted the contest the previous year, apparently forgetting his lines and causing something horrible (which was mentioned but never explained). An upcoming episode — "Good Wilt Hunting" — will have Wilt searching for his creator after he didn't show up at a reunion picnic for the friends. Phil LaMarr plays Wilt.
Minor characters
Ball-and-Chain Extreme-o-saur
Seen in "House Of Bloo's", this monster, which is similar in appearance to Nintendo's Chain Chomp from Mario games (although after it lost its' chains it ressembled Pac-Man), was one of many "Extremeasaurs" that were created by jerky teenage boys. This one was kept in the back of the house far away from trouble until Duchess and Terrence conspired to rid themselves of Bloo by letting it out of its cage. When Eduardo broke one of its tentacles, the broken pieces turned into bombs. More types of these monsters were seen during "Eddie Monster" when Eduardo tries to find their "whizzbee" (a parody of the Frisbee) when it lands in their cage, and another was seen in "Challenge of the Superfriends" when one escaped at the outset threatening to destroy the town where Foster's is located.
Beagle-Puss Rubber Chicken
This friend, who debuted in "Phone Home", is a cross of classic comedy props: The arrow in the head comes from the early stand-up career of Steve Martin during his "Wild-and-crazy-guy" era, the bag comes from "The Unknown Comic" (a.k.a Murray Langston) from The Gong Show, his voice (and the beagle-puss) are done in the Groucho Marx style of humor, and his body is a rubber chicken. He once attempted to flirt with a disguised Frankie. Tom Kenny does this character's voice.
Bendy
The titular character of "Everyone Knows It's Bendy", who was influenced in design by Dr. Seuss, was blamed by the parents of a young boy for all the trouble caused around their house, and was left at Foster's as a result. He then wreaks havoc around the residence, breaking a vase, leaving potato chip crumbs on the floor, and other such actions, each time pinning the blame on someone else. He acted the part of the innocent victim so believably that both Frankie and Mr. Herriman would not believe the other friends. Bloo was eventually able to expose Bendy, but ruined the house in the process. Bendy's voice was provided by Jeff Bennett.
Berry
A seemingly cute, pinkish-red creature seen in "Berry Scary", she arrives to make Foster's her home. Once there, she falls in love with Bloo and wants to be with him forever, that is until she meets Mac. During Mac's and Bloo's attempts to break world records, the jealous Berry sabotages them by "accident." While attempting to break a world record for the largest rubber-band ball, the tables are finally turned as Mac snaps the last rubber band, and with Bloo's help, shows the world what she is really like. In the process, she rolled out of the house, and also set the world record for longest distance traveled by an imaginary friend while strapped to a giant rubber band ball. The psychotic imaginary friend, who speaks with "berry" in sentences similar to what the dialogue in the Smurfs TV series sounded like and how Strawberry Shortcake speaks, is voiced by Grey DeLisle.
Big Baby
Big Baby, as the name suggests, is a huge toddler. First seen in "Partying Is Such Sweet Soireé", as Mac was on his sugar rush taking everyone's candy (including the baby's, derived from the cliché "Like taking candy from a baby"), this giant child has been seen also in "One False Movie" and "Cuckoo for Coco Cards". Grey DeLisle voices Big Baby.
Bloo Clones
When Mac publicized Foster's by using Bloo as part of his show-and-tell at the start of "Bloo's Brothers", the other kids were so amazed that they decided instead to create their own versions of Bloo instead of adopting friends from Foster's. All the kids eventually dropped off their various Bloo clones for various reasons, such as their parents not wanting them or they didn't look right. The real trouble, though, begins when Mac comes to pick up Bloo for a trip to the "Ice Charades", to which they had gotten front row tickets (they sat in the second row, despite this fact) as thanks to Frankie and the others for helping out. After eliminating most of the clones, it came down to two Bloos. One performs a moving speech inspired by Jerry Maguire; a little too moving to be from selfish Bloo. Sure enough, Mac knows better and finds the real Bloo. After this, Joe Icecharades comes to the house to tell everyone that the show has been cancelled because the Olympic Gold Medalist that plays the blueberry broke his/her leg. Mac gives him the idea for a replacement "Blooberry." Look closely (as they go by fast) for Bloo clones that look like internet toon Homestar Runner and underacheiver Bart Simpson.
Cheese

When Mac woke up next to this friend at the start of "Mac Daddy", he immediately assumed that he had inadvertantly created him. In fact, Cheese was imagined by the girl next door, named Louise (who looks like Darla from Finding Nemo), and had a habit of wandering off. Cheese has the personality of a very young child. He (as he often repeats to people) likes chocolate milk and cereal, even though he is lactose intolerant. Allowed to stay at Foster's under the same conditions as Bloo, Madame Foster had a fun time making puns of their names, such as "Mac and Cheese" and "Bloo Cheese." Cheese annoyed Bloo to no end, and Bloo tried to get rid of him multiple times. Such attempts included throwing him over a fence into a playground, sending him to Timbuktu (a possible reference to The Aristocats), throwing him on a bus, and tying him to balloons, among other things before finally settling on locking him in a bathroom. Cheese managed to escape and, after a guilt trip by Mac, Bloo eventually started to imagine the worst possible things that could happen to him in the house, causing Bloo to run around in a panic, searching for him. He was eventually found, and Mac discovered that Cheese wasn't his creation when Louise came to pick him up. Candi Milo provides Cheese's voice, which in design and voice, is eerily similar to the internet cartoon character, Salad Fingers according to blogs and bulletin boards on the web. Cheese made a cameo appearance in "The Big Picture" floating down a river of chocolate milk, and is scheduled to return in the fourth season episode entitled "The Big Cheese". He is deemed one of the most popular "Imaginary Friends" on the show due to his obvious comical bits and odd personality.
Clumsy
Clumsy is an imaginary friend from "The Trouble With Scribbles," who has the head of an elephant, is awkwardy clumsy, and wears a potato sack over his human body. He's so clumsy, he can't walk two steps without tripping. He's possibly a parody of Jar Jar Binks from Star Wars: Episode I The Phantom Menace. Phil LaMarr provides his voice.
Creaky Pete
First seen in "The Trouble With Scribbles", Creaky Pete is one of the oldest friends who lives at the house. He has a body that is completely made from hair, has no legs, and sits in a rocking chair that creaks. He also appeared in "Cuckoo for Coco Cards", when Bloo made him a favor for Coco Cards. Tom Kenny provides the voice of Creaky Pete.
Eurotrish
In "Foster's Goes to Europe", Eurotrish was homesick after being sent to Foster's from her original home in Europe. This friend, with a Scottish tam-o'shanter, British Union Jack dress, Swiss braided hair, Dutch wooden shoes, and speaking with an Italian-Russian-French accent dreams about going back to her homeland. She expresses this through song, doing so consistently throughout the episode. Her song switches from sad to happy and back again as she is given and loses a ticket to Europe as the others decide if they want to go or not. Finally, when she is taken to Europe by Madame Foster and visits her family, they tell her the real reason she was sent away: her constant singing. Her attitude reminds many of Fievel Mousekewitz or his sister Tania from the series of An American Tail movies. Grey DeLisle provides the talking and singing voice for her. Incidentally, her name is a pun of the insult and TV show title Eurotrash and the name "Trish", short for "Patricia".
Goofball John McGee
Seen in "Imposter's Home For Um…Make 'Em Up Pals", Goofball appears to be a normal human teenager, albeit an oddly-dressed one. He wears a spotted tie and a red rubber nose over his common clothing, and cannot seem to remember the exact names of things, causing him to substitute his own approximations, like "Make-'em-up-pals" for "Imaginary friends". Frankie doesn't believe him to be an imaginary friend, thinking that he's a human trying to pass himself off as an imaginary friend. After causing all sorts of problems for Frankie, such as having to wash his dirty football jersey because he is the "mascot" for the football team at John "Larry" McGee's school and ordering pizza after Frankie had to go shopping because he and Blooregard ate everything in the kitchen, Goofball made a call to his family in Canada which he calls "Canadia." As seemingly odd as it is, his red nose (which he bought at the circus) actually hid a small trunk similar to an elephant, and was indeed an imaginary friend, as well and the school's football team mascot. Tom Kenny does Goofball's voice.
Goo Goo Gaga Gaga
The titular character of "Go Goo Go", the fast-talking Goo has a hyperactive imagination; whenever she went near Foster's, she would become over-stimulated and would create a score of new occupants, resulting in her being indefinitely banned from the house. Unaware of the rule, Mac brought her inside after an incident involving an eight-man tobaggan stuck in a tree that Bloo needed (even though it was the middle of June, it was a long story that he didn't feel like telling), which broke the strap on his backpack. In any case, after seeing Bloo, she imagined up a hoarde of similar versions, all with one extra feature or another. After Bloo continued to let her in, Frankie and Mr. Herriman got the mistaken impression that Mac and Goo had a relationship. Overly-nice kid that he is, Mac couldn't effectively get rid of her. After Goo filled the house with so many friends that it became unliveable, Mac finally snapped and told her that he didn't like her. After realizing that she had repaired his backpack strap, he apologized and convinced her to stop creating imaginary friends and find homes for the hundreds she has already conjured. In the end, Goo and Mac become great friends, and in her mission of finding homes for her friends she would replace Wilt as the winner of the "Friend of the Month" award for a long time. Her name is likely to be a reference to the Sonic Youth album Goo which also contained the song My Friend Goo, as well as the stereotypical sound that a baby usually makes (her parents - who don't believe in "stifling" her - allowed her to pick her own name as an infant). Though she has committed herself to not make any more friends, she still sometimes seems to do so accidentally whenever she becomes overly excited. Grey DeLisle lends her voice to Goo, who according to Erik Ghendt, a former animator on the series, makes occasional appearances, her first being in "The Big Picture" and "Neighbor Pains" and will be featured in "Make Believe-It-Or-Not", when she accidentally imagines the villains from a video game.
Imaginary Fleas
Seen in "Land of the Flea", these fleas originally lived on Chewy, Eduardo's imaginary puppy. After a trip to a salon where he got a bath, the fleas escaped to Eduardo's fur, at first it was only two named Juan and Juanita, which later reproduced, where they took up residence and then multiplied by the thousands. Bloo got jealous and wanted the fleas for himself, but Eduardo didn't want to get rid of them. Frankie and Mr. Herriman tried to do so, regardless of this. The fleas ruined every plan that Frankie and Mr. Herriman tried, but ended up on Bloo when he shaved Eduardo and made a coat from his fur. Since Bloo wasn't exactly a model home for them, they took over Mr. Herriman. Ultimately, after negotiations, they were allowed to live in a room that would never be opened again. It was filled with fur shaved from ever furry imaginary friend. Bloo ended up letting them out during the credits. During that same episode, he eventually got "super fleas" that Mac idenitifed as ticks. The fleas' voices were supplied by Tom Kenny and Candi Milo. It should be pointed out that Ms. Milo did the voice of a character named "The Flea" on Mucha Lucha, so this could be considered an inside joke.
Imaginary Man and Nemesister (a.k.a. Nemesis)
Imaginary Man is a superhero friend and Nemesis is his evil sibling, both making an appearance in "Challenge of the Superfriends". This "awesome-rific" superhero wears a white unitard with the initials "IM" on the chest with red and blue trim, much like Major Glory from Dexter's Laboratory. He also resembles another super hero friend who is seen around the house. His right hand can transform into a wide array of gadgets (much like Mega Man); however, he gets weakened in the presense of flowers, citing the fact that their sissiness drains away his manhood (a parody of Superman's weakness to kryptonite, which is even mentioned by Mac). Mac became his sidekick under the name of Mac Attack. Imaginary Man's enemy is Nemesis, who was created by his creator's sister. Her main color is pink (which is part of her never-ending scheme to make the world cute and beautiful) and her hair, dress, and face with blue eyes are shaped like hearts. Her weakness is her hair, which has to be kept in perfect condition in order for her powers (mainly riding on a rainbow, similar to Iceman of the X-Men riding on a bridge of ice) to work. Bloo became "Lord Uniscorn" (a pun on "unicorn" and "scorn;" his costume looked very much like Darth Vader's with a large horn on the forehead), the associate of Nemesis, after Mac Attack temporarily abandoned him following a failed sneak attack at a beauty palor where she was getting her hair done. It was later revealed that they were related when Bloo discarded his evil personna and tried to attack her, only to have Imaginary Man step in and tell everyone that Nemesis was really his Nemesister; Imaginary Man was made up by a little boy years ago, whose sister made up Nemesister "just to bug [them]" (technically, this brings up the question of whether or not these two Friends are siblings or cousins). At the episode's end, Imaginary Man's creator adopts Nemesis for his daughter, and his sister adopts Imaginary Man for her son. Imaginary Man is voiced by Daran Norris, while Grey DeLisle voices Nemesis.
Imaginary Puppies

Mr. Herriman is deathly afraid of dogs, and when Eduardo brings in a puppy — which he named Chewy — in "Who Let the Dogs In?", he freaks out. Mac finds more of these puppies in the back of the house, and when Mr. Herriman calls for a house meeting thinking someone had been trying to take his life, Madame Foster and the others try to keep the puppies away from the rabbit. When it was finally discovered that they were imaginary pets, they were allowed to stay. They have made appearances in two later episodes, "Crime After Crime" and "Land of the Flea", the latter revealing that Chewy has imaginary fleas.
Imaginary Santas
Every time around Christmas, kids imagine up a gaggle of imaginary Santas. Mac and Bloo found out about this trend in "A Lost Claus", as they thought the first one that they saw was the real one, until the second one appeared and fought him. Soon after that, more Santas appeared, and Frankie broke up the fight between the first two and then told Mac that those Santas were imaginary ones and they were as real as her Aunt Fanny. Tom Kane and Phil LaMarr provided the voices of the first two Imaginary Santas. The first imaginary Santa (or one that merely looked like him) came back in "Setting A President".
Ivan

This seeing-eye friend with over a hundred eyes, who was seen in "Sight For Sore Eyes", was lost at a party in Van Dyke Park (a pun on musician Van Dyke Parks) with his blind friend Stevie (a reference to blind musician Stevie Wonder) after Stevie's mother took a flash photograph of both, blinding and disorienting Ivan - who panicked and started running in random directions. After much searching on the part of Mac and Bloo, he was eventually returned, only for the incident to happen all over again. Kevin McDonald gave his voice to Ivan.
Jackie Khones
This small, green one-eyed stick figure has a deep voice. He appears in various episodes to make quick comments on current events, such as after the lengthy introduction of Duchess (using her full name), where he stated "Thank goodness!", ratting out Bloo when he was hiding in flower pots to avoid the New Guy in "Beat With A Schtick", pointing out Mr. Herriman's bag of carrots in "Crime After Crime", or like Blooregard before him (and others later) calling Eduardo a "weirdo" when he sees him talking to himself in "Land of the Flea". His first name wasn't revealed until "Setting A President", while his last name was discovered in "Cuckoo for Coco Cards". At the end of "A Room With a Feud", he inherited the room that was once occupied by Bloo, Coco, Eduardo, and Wilt when they moved into the room next door, but later in "Squeeze the Day" when Bloo is looking for everyone he looks in the attic for Jackie (though, since he looked for Wilt at the basketball court, Eduardo in the arcade, etc., this may just be where Jackie hangs out rather than his room). Jackie's name is a spoonerized version of Cartoon Network executive Khaki Jones. Phil LaMarr provides Jackie's voice.
Mac and Terrence's mother
After one fight too many and blaming Terrence for it as well as Mac and Bloo, it was her decision to get Bloo out of the house and the subsequent path to Foster's in "House of Bloo's". She is quite similar to Ms. Sara Bellum from The Powerpuff Girls, considering that you never see her face (however, you do see the back of her head in "House of Bloo's" when she was talking to her son in his room). She returned to the series in "Duchess of Wails", complaining about the Applebees adopting Duchess and her (sarcastic) thinking about moving to Singapore, which Terrance believed to be in Wisconsin, and in the Christmas special "A Lost Claus" when after Mac asked "What does a guy have to do to get underwear for Christmas?", she remembers to get some for Mac's birthday, as well as socks. Grey DeLisle voices Mac's mother.
New Guy
The New Guy is a tall, light-blue monster-like figure, similar to Sulley in Monsters Inc. or Sweetums of The Muppet Show, seen in "Beat With A Schtick", he feels the brunt of Bloo asking "How's the weather up there?", which prompts the New Guy to glare down at Bloo and tell him to meet him out back at 4 p.m. that day, which Bloo fears the worst of. Bloo desperately tries to get out of what he thinks will be a fatal meeting, while Madame Foster and the others place bets on his survival. In reality, the New Guy is a prop comedian with a fruit-smashing style similar to Gallagher and says that the line he gave him was a "classic". When he asks Bloo for an opinion on his act, Bloo says that it stinks, and the New Guy slams him down with his fist, to which Eduardo says to Jackie "That is the best punchline he delivered all day." He still lives in the house, as seen in "Land of the Flea", where he was willing to donate his fur to keep some imaginary fleas happy, and most recently in "The Big Picture". The New Guy is voiced by Phil LaMarr.
Peanut Butter
This rather unusual character was seen in "A Room with a Feud". Created by a sloppy child, he was chosen by Mac to take an abandoned room when Poindexter Dorkface III, a calculator friend, vacated his room after being adopted by a kid named Moose. He loves oompah music and messy conditions, as well as spiders, all of which Mac and the friends tried to use to drive him out of the room. Peanut Butter is adopted by a schoolmate that Mac brought to the house, named Jerry. Many believe that Peanut Butter was based on Fuzzy Lumpkins, another nemesis of The Powerpuff Girls, as both have antennas, southern accents, and purple hair.
Red
Created by Terrence in "Seeing Red" to get rid of Bloo while bothering younger brother Mac at the home, he turns out to be the opposite of his creator's persona, even after Bloo abuses him on a tour, during which Red is stung by imaginary bees, eaten and spat out by a sea serpent, and jabbed in the rear-end by the horn of a winged unicorn which he called a "pretty horsie" (it was a male unicorn). Because Terrence is Mac's brother, Red would be in turn Bloo's cousin (or, as seen in Challenge of the Superfriends, they would be brothers), and it is not known if the same rules would apply in his case. When Terrence tells Red to "kill, smash, maim, destroy (and) crush" Bloo, Red sees right through the ruse, and promptly attacks his creator, throwing Terrance into the same situations that happened to Red. Red's voice was provided by Phil LaMarr.
Scribbles

Appearing in "The Trouble With Scribbles", these are the first imaginary friends of babies and only can only perform singular tasks. They were released by Bloo (accidentally) from the room they had been permanently locked in. The reason the Scribbles were locked away was because there were far too many of them, and Mr. Herriman thought they were more trouble than they were worth (until they showed hidden talents). The appearance of the Scribbles as well as the name of the episode in which they appear is an obvious parody of the tiny, furry, endlessly-multiplying balls of fluff called Tribbles on Star Trek. The only Scribble still living in the house at the end is the one that gives raspberries, much to Bloo's delight. In Big Fat Awesome House Party, a common chore is to collect a few Scribbles scattered throughout the house.
Snooty mom and dad and their bratty daughter
A family who appeared in the "House of Bloo's" pilot episode, the snooty mom and dad are millionaires with an equally snooty, as well as bratty, six-year-old daughter. While they were in the midst of adpoting Duchess, their six-years-old daughter decided that she wanted to adopt Bloo instead, and rename him "Tiffany." Eduardo, Wilt, and Coco all tried to stop her, intercepting Bloo along the way (thinking the same thing but in the midst of the confusion, trying to keep Blooregard from one another), but then Mac arrived to save the day. The father is a spoof of the titular character's father from Dexter's Laboratory, while the mother was inspired by kindergarten teacher Ms. Keane and the bratty daughter was likely inspired by Princess Morbucks from The PowerPuff Girls, two series that Craig McCracken has worked on. Phil LaMarr] did the dad's preppy voice, while Tara Strong provided the voices of both the mom and the daughter.
Uncle Pockets
The first, and considered by many at Foster's to be the best, imaginary friend to come to Foster's, he looks a bit like Willy Wonka from Charlie and the Chocolate Factory and speaks in Seussian rhyme. He returned for a visit as the central character in "Bloo Done It". Bloo, who has started up a new in-house newspaper, believes that he's up to no good and thinks that he is trying to rid the house of their matriarch by "rubbing her out." In reality, he was giving Madame Foster a trip to a day spa as a thank you for all the work she has done, which included a massage, and carries momentos of all the friends that he's made in his life. He made a cameo in "The Big Picture" in the old house photos, and Mac and Bloo dig up his stuff again in "Squeeze the Day" (where Bloo remarks that 'this stuff wasn't even interesting the first time'). Uncle Pockets, whose name comes from a Danny Kaye children's song, was voiced by Kevin Michael Richardson.

Imaginary friends
Throughout the episodes of Fosters Home for Imaginary Friends, there have been a great many characters used as jokes in conversation, such as Willy Nilly, who was imagined by someone named Kevin. Often times, the tools used by the imaginary friends will be other imaginary friends that are basically talking versions of those tools, such as Fridgy the Refrigerator, Bulby the Lightbulb, Flashlighty the Flashlight, Rolley the Rolling Pin, Oveny the Oven, Copy the copying machine, Wally the wall, Camery the still camera and so on in that fashion. There are also some imaginary friends that are types of food, such as George the Cookie, Charlie the Chicken Leg, the Pizza Slice (who was immediately eaten by Terrance), and a giant Gummi Bear.

"Adoption" online
In 2005, Cartoon Network's Latin American service website gave viewers a chance to adopt an imaginary friend online, with Bloo, Wilt, Coco, and Eduardo as their choices. Similar to the Neopets site, the web surfers gave their friends food to eat (some good, some not so good) and games to play to keep their imaginary friend happy. At the end of the promotional period, the adoptees got a certificate thanking them for participating. In September of that same year, a similar month long game was launched in the USA on Cartoon Network's official site, along with a separate link at FostersFriends.com. In addition to the four previously mentioned friends, players could adopt Berry, Uncle Pockets, Cheese, or Ivan. This updated version also used the voice actors associated with those characters, improved graphics, and increased use of Flash animation. Until December 10, 2005, those who made adoptions were able to keep an eye on them.
Big Fat Awesome House Party
Since May 15, 2006, fans have been able to explore Foster's with their own friend in the online game Big Fat Awesome House Party, featured on Cartoon Network's website. Kids create a friend and explore the house doing chores, favors, adventures, and mini-games. Main characters will stay in one room while minor characters pop up all over.
