History WesternAnimation / FostersHomeForImaginaryFriends

Why to Foster's Home for Imaginary Friends, of course! A home for imaginary friends whose kids have outgrown them, Foster's is a place where friends can live together until they are adopted by another child who needs them.

Set {{in a world}} where imaginary friends are living, tangible beings who [[{{Tulpa}} can be seen and heard by everyone]] including their creator, ''Foster's Home For Imaginary Friends'' follows Mac (Creator/SeanMarquette), a shy and creative 8 year old boy, who is forced by his mother to give up his imaginary friend Bloo (Creator/KeithFerguson), a walking, talking protection blanket. He and Bloo discover the titular home for Bloo to live, but because they don't want to be separated forever, they strike a deal with the house that, as long as Mac comes to visit him every day, Bloo won't be adopted.

Upon arrival, Bloo makes three new friends: Wilt (Creator/PhilLaMarr), a tall, basketball-loving monster who ApologizesALot; Eduardo (Creator/TomKenny), a ferocious-looking but kind bull-like imaginary friend who's [[ShrinkingViolet afraid of his own shadow]]; and Coco (Creator/CandiMilo), a kooky bird/airplane/palmtree creature [[PokemonSpeak only capable of saying her own name]] who can lay eggs that hatch into anything she imagines. As all of the other characters were once dreamed up by children, the house's other residents are a CastOfSnowflakes made up of an array of wildly surreal creatures. Most of the episodes involve Bloo's egotistical, mischievous personality, in complete contrast to the shy, polite Mac, getting him and his friends into wacky hijinks around the house. As with most Cartoon Network shows, expect plenty of {{parental bonus}}es along the way.

In 2012, the series returned to Cartoon Network as a part of ''WesternAnimation/CartoonPlanet'', although strictly the 11-minute minisodes, since the block doesn't incorporate any 22-minute episodes of former network series. Also as of 2012, reruns began airing on Creator/{{Boomerang}}. [[https://variety.com/2022/tv/news/powerpuff-girls-fosters-home-for-imaginary-friends-reboots-1235318832/ On July 18, 2022]], it was announced that Craig [=McCracken=] would return to the series to produce a preschool spin-off with [[Creator/HannaBarbera Hanna-Barbera Studios Europe]], featuring an original cast of imaginary friends.

After wrapping up four seasons and [[WesternAnimation/ThePowerpuffGirlsMovie a feature film]] of ''WesternAnimation/ThePowerpuffGirls1998'', Creator/CartoonNetwork approached Creator/CraigMcCracken for a new series. He pitched them this simple premise: where do {{imaginary friend}}s go when their young creators outgrow them?

Of note, ''Fosters'' was Cartoon Network's first original 2D animated show to be produced 100% digitally: the backgrounds were all drawn in Photoshop and the animation was done in-house in UsefulNotes/AdobeFlash, all with the aide of graphics tablets. This not only brought down the cost and shrank the staff, but allowed for the nuances of Craig [=McCracken=]'s personal drawing style to come through in the final product rather than the blocky, geometric look Flash had been known for up to that point.

A total of 79 episodes in six seasons were produced, along with two DarkerAndEdgier {{Made For TV Movie}}s: ''WesternAnimation/GoodWiltHunting'' in 2006, and ''WesternAnimation/DestinationImagination'' in 2008. The series ran from 2004 to 2009 and, as a result, is seen as the bridge between Cartoon Network's "classic" and "renaissance" periods (coincidentally, it ended the same year as the station's longest running series, ''WesternAnimation/EdEddNEddy'').

Has a [[https://tvtropes.org/pmwiki/crowner.php/BestEpisode/FostersHomeForImaginaryFriends Best Episode]] Crowners page.

* SadistShow: By Season 3.
* SanitySlippage: When Madame Foster makes cookies to sell to the townspeople for money for a new roof, Frankie later eats some cookies and becomes addicted to them to the point where she goes insane without them especially when finding out that Madame Foster only bakes them once a year. She sleeps in a sleeping bag outside next to the cookie stand and screams at Mac for being just two minutes late with the cookies and demands him to give her forty dozen boxes of cookies. It gets to the point where she stock piles the forty dozen boxes of cookies and several jugs of milk and is lying on her back in her bed gobbling the cookies and milk down at a fast pace with her eyes bulging with craziness and loses the will power to stop eating them and Mac tries to intervene with no success.
* SavvyGuyEnergeticGirl: Mac is intelligent, while his friend Goo is perky and eccentric.
* {{Schemer}}: Bloo is often coming up with schemes to get what he wants.
%%* ScoobyDoobyDoors: Subverted.
* SealedEvilInACan: This is how the parents of the boy who created World viewed him when they locked him in his toy box, and apparently told Foster's such as they kept him in there. However, this is a subversion as World wasn't evil, just misunderstood and just wanted friends.
* SecondPersonAttack:
** In one episode, when Bloo gets punched in the face by a young girl for taking some toy glow-in-the-dark vampire teeth.
** In another episode, Bloo is spying on who was supposed to be "the best imaginary friend ever", and he knocks out Bloo with a shovel this way.
* SelectiveEnforcement: Inverted as a SpringtimeForHitler in the episode "Crime After Crime". The episode's B-plot has Frankie [[LethalChef cooking something disgusting]] for dinner, so Bloo causes trouble in an effort to get sent to his room without dinner. Unfortunately the episode's A-plot was Mr. Harriman acting hyper-paranoid over someone discovering his addiction to carrots, leading him to punish everyone else in the house for relatively minor infractions due to thinking they're "on to him" while completely ignoring or even ''congratulating'' Bloo.
* ShaggyDogStory: Many, many, ''many'' episodes.
* ShapedLikeItself: In the episode "Bloo's the Boss", a newscaster states about Madame Foster, "If only everyone in the world had a heart as big as hers, then the world would be filled with really big hearts."
* SheIsNotMyGirlfriend: Mac, concerning Goo (in the first episode she was in, anyway).
* ShipTease: Mac insists Goo isn't his girlfriend, but the two have their moments nevertheless.
* ShoutOut: Has its [[ShoutOut/FostersHomeForImaginaryFriends own page]].
* SiblingRivalry: One-shot friends Imaginary Man and Nemesister were created by a boy and his sister as an extended outlet for their rampaging animosity. Their creators come back at the end of the episode to adopt them for their own kids.
* SlapstickKnowsNoGender: Frankie and Madame Foster are occasionally on the receiving end of whatever physical gag happens to occur around them. Frankie in particular gets smacked around so much that she even becomes the ButtMonkey for some episodes.
* SmallNameBigEgo: Bloo is an arrogant prick who thinks he's better than everyone else.
* SmoothTalkingTalentAgent: In "Sweet Stench of Success", Bloo is convinced by Hollywood talent agent Kip Snip to advertise his terrible deodorant (which actually made people smell worse). [[spoiler:Kip also tricked Bloo into signing adoption papers rather than a contract, allowing him to exploit Bloo even further.]]
* SoapPunishment: Discussed in "Crime After Crime"; Mr. Herriman makes up new rules so no one will suspect his carrot addiction, one of which involves not standing on rugs. Wilt stands on a rug upon hearing this new rule, and throughout the episode, he tries to decide on how to punish himself. At one point, he suggests washing his mouth out with soap, but decides against it because if he did that, he'd be touching the soap (as Herriman had earlier punished some other imaginary friends for touching toys).
* SoapWithinAShow: ''The Loved and the Loveless'' is an in-universe soap opera.
* SoulEating: The guys watch a [[BMovie horror movie]] about a "cannibal ghost", who "scares you to death and eats your ghost".
%%* SpeakNowOrForeverHoldYourPeace: Subverted.
* SpottingTheThread: Mac is forced to decide between Bloo and a near perfect impostor, and picks the real one because the impostor's friendship speech is ''too nice''. Mac knows Bloo is a {{Jerkass}}.
* SquashedFlat: Bloo in "Adoptcalypse Now", when a giant, gorilla-like imaginary friend is launched through the window and lands on him.
* SquishyWizard: Mac is highly intelligent for an 8-year old, but one drop of sugar and he goes from being the OnlySaneMan to making ''Goo'' look perfectly sane.
%%* StabTheSalad
* StalkerWithACrush: Berry won't leave Bloo alone.
%%* StartMyOwn
* StealthPun:
** Cheese has a few of these: Mac created Cheese. You know, "Mac and Cheese?"[[note]]Macaroni and cheese is a popular, easy to make dish in many English-speaking countries.[[/note]] Making Mac's two creations Bloo Cheese.
** When Bloo tries to get Cheese adopted, he offers a package deal with a RidiculouslyCuteCritter named... Crackers.
** Bloo and Berry. As Berry has a crush on Bloo, this is not accidental.
%% Mac and cheese is not a universally known dish, hence the note.
* StrangeMindsThinkAlike:
** In "Bloo's the Boss" Bloo finds a cat and names him Chuck. Later when the cat's owner comes to collect him it turns out Chuck just happened to be his real name. The same thing happens when Bloo decides to name an imaginary friend Wally just because "he looks like a Wally." In the next scene, it's revealed that that was his real name, again because he looks like a Wally.
** In "Duchess of Wails" when Mac's mom tells him they're moving Terrence tells him they're going to Singapore, which Terrence says is all the way in Wisconsin. Cut to Bloo asking Mac, "So you're saying Singapore is ''not'' in Wisconsin?"
* StrawFeminist: Subverted with Nemesister, who doesn't really have a political agenda. She just likes to destroy or sabotage anything that guys like.
* StuckInAChimney: In the ChristmasEpisode "A Lost Claus", Bloo sends out all of his friends to try and prove to Mac that Santa exists. He makes Eduardo climb through the chimney, but he gets stuck there for most of the episode, until something pushes him out.
* SuicideAsComedy: In "The Bride to Beat", Bloo has a pair of conversations with a suicidal imaginary friend who seems like he's going to jump off the roof. Both times, Bloo pushes him off (though he survives both falls).
* SurvivalMantra: Mr. Herriman chants ''"A dog is not in the house presently"'' several times in "Who Let the Dogs In" to try and get over his fear of dogs.
* SurprisinglyRealisticOutcome: Happens surprisingly often, even as entire episode premises:
** For example, when Little Lincoln turned out to be a scam artist in a TheFarmerAndTheViper type of plot, sold the imaginary friends to be used as mascots, planning on turning the home into a casino. The only reason he was stopped is Madame Foster tricked the bodyguard (who always got Little Lincoln back off of whoever captured him) and instead of signing it over, chewed on the pen-based imaginary friend to get him to cooperate in confessing his crimes and getting the friends back one by one.
** Mr. Herriman having trouble working as a grocery store cashier after losing his job as house president. Many administrators often find themselves struggling with ground level or menial jobs. Of course, FridgeLogic comes in given that he looked for every job BUT an administrator, which he was quite skilled at.
** When Kip Skip admitted on live television that his deodorant brand is designed to make people smell worse instead of better, he's arrested for false advertising.
* SuperOCD: Mr. Herriman, to the point where he once made the entire house ''alphabetize trash.''
* SweetTooth: Inverted with Mac; sugar is his GRatedDrug, making him tear off his clothes and run around outside.
* SummonBiggerFish: In the Halloween episode, Bloo believes that everyone in the house has turned into zombies (it was actually an extremely elaborate practical joke that they all orchestrated due their annoyance at him always playing the Spring Snakes in a Peanut Can gag every Halloween). In order to combat them, he steals the candy from a trio of trick-or-treaters and [[ForceFeeding force feeds]] it to Mac, knowing that Mac in his sugar-induced rampage state is stronger than any group of zombies. Of course, this works out against him when it's all revealed to be joke, considering he ended up creating a sugar-hungry monster on Halloween of all nights.
* TakeOffYourClothes: Invoked by name by Eduardo during the Funny Bunny crisis. Mac tries to hide all evidence of the Funny Bunny video, including the various clothing many people are wearing. Cue Eduardo running through the house, shouting, [[ItMakesSenseInContext "Take off your clothes! Take off your clothes!"]] The only person who unquestioningly complies is [[{{Cloudcuckoolander}} Madam Foster]].
* TalkativeLoon: Goo and Cheese. Emphasis on "talkative" in Goo's case, and "loon" in Cheese's case.
%%* TandemParasite: Mr Herriman does it Bloo in "Let Your Hare Down".
* ThisMeansWarpaint: Mac dons warpaint on his face in "I Only Have Surprise For You" when he [[spoiler: tries to sabotage his own surprise birthday party.]]
* TheEighties: The series takes place in the mid 2000s but one episode revolves around Mac trying to be cool. At one point he starts acting like a stereotypical 80s bad boy.
%%* ThrowTheDogABone
%%* ThunderingHerd
* TickleTorture:
** In the episode "Make Believe it or Not", Bloo and Mac are subjected to this via a RoboticTortureDevice called the "Insanolizer".
** In the episode "Race for Your Life, Mac & Bloo", Mac tries doing this to Bloo to make him lose the race.
** In "The Bloo Superdude and the Great Creator of Everything's Awesome Ceremony of Fun That He's Not Invited To", one of Bloo's hallucinations involves him receiving this from Frankie to make him eat his soup.
* TimeZonesDoNotExist: Averted in "Foster's Goes to Europe". when Mr. Herriman presents a schedule for gang's European trip, only to take it back for revisions once Mac reminds him of the different timezone.
* ToiletHumor: Done a lot with Cheese (and to a lesser extent, Bloo)
* TomboyishName: Frances "Frankie" Foster.
* TooSpicyForYogSothoth: Extremosaurouses are perfectly willing to eat ''good'' people, but they will vomit up evil people after taking a few bites. Apparently, bad tastes bad.
* TrademarkFavoriteFood: Cookies for Frankie.
* TrickedIntoSigning: A producer named Kip Snip entices Bloo into signing an acting contract. However, Bloo didn't ReadTheFinePrint, and it turned out that he had been tricked into signing an adoption paper. [[spoiler:The papers ended up being null and void because it wasn't run through Mr. Herriman first.]]
* TroubleMakingNewPet: Imaginary friends aren't pets, but nonetheless the episode ''Everyone Knows It's Bendy'' plays this straight. Bendy is apparently wrongly blamed for all the misdeeds that he committed at his old creator's home, but once he's been welcomed to Foster's, he actually turns out to be a complete {{Jerkass}} who promptly gets Wilt, Eduardo, Coco, and Bloo into various kinds of troubles that he did himself, while still mooching to Mr. Herriman and Frankie under his innocent facade.
* TookALevelInJerkass: Bloo after the pilot episode became an obnoxious and self-centered jerk with very few redeeming qualities.
* TotemPoleTrench: Standing on each other's shoulders as a disguise was done by Mac and Bloo to the point of being a RunningGag. Wilt once substituted as a majority of Orlando Bloo.
* {{Troll}}:
** Bloo in spades. About 95% of his screen time is devoted to him finding creative ways to troll people.
** Bendy from "Everyone Knows It's Bendy" is even worse than Bloo.
%%* TrashTheSet
* TrueCompanions: They may get into their squabbles, but Mac and Bloo are always there for each other.
* {{Tsundere}}: Frankie Foster, who is a type B. She's a CoolBigSis to the Imaginary Friends, though she loses it around Bloo and Mr. Herriman.
* {{Tulpa}}: The imaginary friends are thoughtforms taking on lives independent of their creators.
* UnflatteringIDPhoto: In "Bus the Two of Us", Bloo uses Frankie's drivers' license, complete with a silly-looking photo, to fool a traffic cop into thinking he's her (Fun Fact: It's the same photo used in Mr. Herriman's attack ad against her in "Setting a President").
* UnimpressiveProgressReveal: In "Camp Keep a Good Mac Down", Mr. Herriman ventures into the forest in search of food for his friends, and he becomes more afraid the darker and more mysterious it becomes. And he starts to panic.
-->'''Mr. Herriman:''' Oh. Oh dear. My bearings, they seem to have become misplaced. What's that noise? Hello?! HELP! HELP! ''MADAME FOSTER!!!''\\
'''Madame Foster:''' Yes?\\
''(cut to reveal he's only a few feet away from the camp)''\\
'''Mr. Herriman:''' ''(nervous laugh)'' I mean, t-that's what you ''would'' have said if any of you went into the woods. ''(laughs)'' ...Tally-ho. ''(hops into the woods)'' A-hunting we will... Hello? ''Hello? HEEEEELP!''\\
''(Madame Foster facepalms)''
* TheUnintelligible: Coco. Her only dialogue is sequences of "Coco!". Certain characters seem to be able to understand her, notably Wilt and Eduardo, but to most of the rest of the cast she's as unintelligible as she is to viewers.
* UnsympatheticComedyProtagonist: Bloo's a selfish jerk to everyone.
* UnwittingInstigatorOfDoom: Mr. Herriman in "Imagination Destination", when he admonishes World for everything he has done right after Frankie has calmed him down. See InterruptedCooldownHug for more.
* VillainousBreakdown: While he's not intentionally a bad guy, [[BigBad World]] has one at the climax of TheMovie when Mr. Herriman threatens to leave him sealed in his toy box alone again, causing him to snap and reduce his world to a white void and go OneWingedAngel. It takes Frankie's kindness to snap him out of it and calm him down.
* VileVillainSaccharineShow: The main series has Berry, a sociopathic StalkerWithACrush who's willing to commit ''murder'' to get what she wants. ''Good Wilt Hunting'' has Foul Larry, a rude, violent friend [[spoiler: who caused Wilt to lose both his arm and his eye.]] ''Destination Imagination'' has [[TragicMonster World]], a RealityWarper who's severe emotional problems makes him violently dangerous and selfish.
* VisualPun: Duchess. At the start of the series, she's full of herself an generally an AlphaBitch. At the end of the series, she's still full of herself and an AlphaBitch. The literary term for a character who does not go through any changes is called a "flat character." Duchess is two-dimensional ([[PaperPeople she is literally a flat character model]]).
* VitriolicBestBuds: Mac and Bloo sometimes, particularly in episodes where Bloo is especially obnoxious and Mac is especially mature. Other episodes show very well that they have more in common than they seem.
* WalkIntoCameraObstruction:
** "House of Bloo's Part 1" at the beginning with Terrence where he chases Mac and Bloo. And again with Eduardo and Bloo when Ed is being chased by Bloo.
** "House of Bloo's Part 2" with Mr. Herriman as he's walking to his office.
** "Dinner is Swerved" when Bloo is chasing a giant chicken leg.
** "Adoptcalypse Now" happens twice in a row when Mac chases Coco
** "Store Wars" with Bloo when he goes up an escalator.
** "Bloooo" when Wilt, Coco, and Ed chasing white Bloo, Ed fills the screen.
** "World Wide Wabbit" with Herriman when he goes to his office looking for a file.
** "Partying is Such Sweet Soiree" when Ed is riding his bike his face fills the screen.
** "Sight For Sore Eyes": happens twice in a row two times with Bloo and Mac. Once when Bloo is goes after some kid mistaking him for Stevie. And again when he charges at a birthday party.
** "Squeakerboxxxx" while Bloo is replacing the new squeak toy with the broken one, Eduardo runs in.
** "The Land of The Flea" Twice. At the beginning when Eduardo is skipping out of his room to the salon. And again when he runs away from monkeys screaming "WHHHHYY?!"
** "The Big Cheese" with Mr. Herriman when he tries to demonstrate the security system. And again with Cheese and Bloo while all the friends are chasing Cheese.
** "A Room With a Feud" while Bloo and the others are chasing Peanut Butter, Mac, looking annoyed, walks into the camera
** "Nightmare On Wilson Way" Three times. When Eduardo hears Frankie come back in the house, he runs screaming her name; then Bloo and Coco follow him. And then Ed, Bloo, and Coco altogether as they run to the foyer.
* WalkingAwayShot:
** "Phone Home", twice with Bloo; going out to find a friend to take home, and with him chasing the man in the phone suit
** "The Big Lablooski" with Eduardo about to bowl and Jerkins scares him.
* WalkingSpoiler: In ''Affair Weather Friends'', has a rich boy Barry Bling wanting to have Bloo for himself. [[spoiler:Turns out that Barry Bling was just Berry from ''Berry Scary'' in disguise]].
* WalkThroughTheCamera:
** House of Bloo's Part 1; Where Bloo opens the gate and walks into Foster's.
** Adoptcalypse Now; Where Bloo is running away from a group of kids.
** Phone Home; An imaginary bone being chased by dogs
** Bloo's Brothers; With Bloo pushing Mac to the front of the classroom
** Better Off Ed; Where Eduardo is looking for Scrappy and gets interrupted by Jackie Khones.
** This Little Peas; Peas is running about to jump into an elevator
* WelcomeTitles: The title cards.
* WhatWereYouThinking: Mac often admonishes Bloo for his inane conclusions and plans.
* WhamLine:
** A rather quiet one in the pilot. When Mr. Herriman tells Frankie that every child eventually outgrows their imaginary friend, she just gives him a knowing smile and says "Yours didn't," then walks past a portrait of the woman who later turns out to be Madame Foster.
** From "Challenge of the Super Friends", we have this one from Imaginary Man, which changes ''everything'' we know about his interactions with the episode's villain, Nemesis...
-->'''Imaginary Man:''' (''[[SaveTheVillain rescuing Nemesis from Bloo]]'') Nobody pulls my Neme''sister's'' hair but ''me!''
* WhiteGloves: Mr. Herriman wears a pair of white gloves.
* WhoEvenNeedsABrain: Type II is used in an [[ShowWithinAShow in-universe movie]] in the episode "Cheese a Go-Go", where a woman who has had her brains sucked out by aliens shushes her love interest and informs him that she's hiding from the aardvarks.
* WiseBeyondTheirYears: Mac tends to be more insightful and intelligent than your typical eight-year-old, though he can be as childish as the rest of them at times.
* WithFriendsLikeThese: Mac and Bloo. [[DependingOnTheWriter More prominent in some episodes than in others.]]
* WoobieDestroyerOfWorlds: World from ''Destination Imagination''. Justified since it's ''[[RealityWarper his]]'' [[RealityWarper world]] anyway.
* {{Yandere}}: Berry for Bloo. She's absolutely nuts for him.
* YetAnotherChristmasCarol: Bloo tries to pull one of these on Mr. Herriman. It doesn't work. In fact, it makes things ''worse''.
* YouWontFeelAThing: "Seeing Red": Terrance says to Mac before beating him up "This will only hurt for a second." The line becomes a RunningGag throughout the episode, and at the end is given an IronicEcho by Bloo: "Don't worry, it'll only hurt for a week."
* ZombieApocalypse: Subverted [[spoiler:It was only a Halloween prank meant to get back at Bloo. Pretty convincing though.]]

%%* MagicFloppyDisk: Played straight in one episode, averted in another. [WHICH?]
* MathematiciansAnswer: The seeing-eye friend they try to help in one episode apparently discards any information not related to "this is a danger from which I must keep my child", because when he loses track of the kid, he can't provide a helpful answer; he was in a place when he lost Stevie, and as for Stevie himself, well, he's got arms, a face...you know, standard-issue human stuff.
* MaybeMagicMaybeMundane: Regarding the Foster house itself. As convoluted as it is to get around and how it can house such fantastic creatures as imaginary friends, it's been asked once if the house ''itself'' is an imaginary friend. No definitive answer is ever given.
* MeanBoss: Mr. Herriman is always demanding Frankie to tend to everything that needs to be taken care of, even when she's busy taking care of something else.
* MeatOVision:
** Exaggerated in "Dinner is Swerved", in which Mac and Bloo are lost in the house for several hours and Bloo nearly eats an anthropomorphic chicken leg imaginary friend.
** Parodied in "Read 'Em and Weep", where Sam Burger and his adopter Ronald get stranded on an island and Ronald hallucinates Sam as a giant chicken leg when he's already a sentient hamburger.
* MediumAwareness: In "Room With a Feud", Peanut Butter says that he should be allowed to participate in the competition for the room that Bloo, Wilt, Eduardo, and Coco are having because he's a member of the house and asks, "What's this, ''The Wilt, Ed and Coco Show''?"
* MilhollandRelationshipMoment: Done in one episode when Bloo breaking Mr. Herriman's most prized possession, a bust of Madame Foster. Having already fallen victim to Herriman's occasionally arbitrary rules (earlier, Bloo, in desperate need of some toilet time, is forced to first go through an entire morning routine by the rabbit), he's now done something that even he has to acknowledge is legitimately worth punishing—and he can only imagine what horrors Herriman has in store for him. He goes to such trouble to cover up his mistake that at one point he even enlists the help of Madame Foster herself to impersonate her own bust. When Herriman turns out to have a collection of spares and a completely philosophical attitude towards their breakage, Bloo nearly explodes. Then Frankie, who was knocked out and shoved in the closet the spares were stored in, wakes up and accidentally breaks them all.
* TheMillstone: In "Berry Scary", Berry tries to convince Bloo that Mac is the Millstone who is preventing him from getting the world record. Ironically, Bloo himself is generally the Millstone to everyone else at Foster's, to the point where in the very same episode he mentions that being a burden is his 7th favourite thing.
* MiniatureSeniorCitizens: Madame Foster. She's one of the ''shortest'' of all the main characters - hair notwithstanding, she's roughly the same height as Bloo - while Frankie, her granddaughter, is of average human height.
* MirrorCharacter: Mac usually plays TheStraightMan to Bloo's antics, and is often exasperated by them, but during some of Mac's wilder moments he acts pretty much EXACTLY like Bloo does.
* MissingTheGoodStuff: The plot of the episode "Where There's a Wilt, There's a Way" involves Wilt missing a basketball game he'd been looking forward to because he can't say no when people ask him for help.
* MockMillionaire: In one episode, several charities compete for the attention of a character pretending to be a millionaire.
* MotorMouth: Goo always talks very fast.
* TheMovingExperience: The focus of the final episode is that Mac is believed to be moving, which could jeopardize Bloo's immunity to being adopted by a new kid.
* MultipleEndings: Two endings to "Race For Your Life Mac & Bloo" were made in which the winner of the episode's race differed between Mac and Bloo. A poll was held on Cartoon Network's website to determine which ending was used, and the winner was Mac. The "Bloo wins" ending was posted on the website for a period after the episode's airing, and an alternate version of the entire episode with that ending is availble on digital services where the show can be bought as well as Creator/{{Hulu}} (but not Creator/HBOMax).
* MundaneFantastic: Anything a child imagines can come to life in this world. Despite this, the world is otherwise much the same as ours.
%%* {{Namedar}}
%%* NeverGrewUp
* NeverMyFault: Bloo refuses to accept it's his own fault Eduardo ran away in that episode.
%%* NoCelebritiesWereHarmed: Wilt's creator, Jordan Michaels, is obviously based on famous basketball player UsefulNotes/MichaelJordan.
* NoFullNameGiven: Almost everyone has only a first name, like Mac, or only a last name, like Mr Herriman. Only two main cast members are exceptions; Frankie has a last name by association (she's Madame Foster's Granddaughter, and her ID confirms her last name is Foster) and Bloo, because a 3-year-old Mac apparently thought "Blooregard Q Kazoo" was a great name.
* NoNameGiven: Mac's teacher was never given a name.
* NoodleIncident:
** In "Bloo's Brothers", Mac's classmates imagine weird clones of Bloo, only to leave them at Foster's; Frankie sees the clones and angrily asks the original if he played with Mac's chemistry set ''again''... he says he did, but "these" clones did not come from it.
** In "Hiccy Burp", the rest of the house forces Wilt to keep practicing his lines for the pageant, remarking that his act last year was a disaster. We never get the exact details.
** The beginning of "Duchess of Wails" has Duchess angrily fling off a dress Madame Foster made for her and declare that she'd rather go naked. Madame Foster begs Duchess not to go through with it, one of her exclamations being "Not again", which implies that Duchess chose to go naked out of contempt for a dress not made to her liking before.
** The ending of "Squeeze the Day" has everyone at Foster's (minus Bloo) returning from a bad day at the beach that resulted in the governor banning them from ever returning. We never fully learn what happened that caused this other than it was Wilt's fault and it resulted in a bunch of dirty sand and homeless jellyfish.
** In the DVD commentary of "Store Wars", Bloo mentions '''4''' separate incidents he had caused: something involving Eduardo's hair and a clogged toilet, filling Mac's backpack with pudding to the point that it leaks, causing Wilt to trip and break his toe, and having Coco be flown from a catapult and end up trapped up a tree. The real kicker? Bloo mentions, almost ''confidently'', that all 4 incidents happened ''on the same morning.''
* NotAllowedToGrowUp: Mac is eight when the show starts, and does not age for the duration of the show.
* NotQuiteHuman: Any child can imagine up ''any'' sort of creature whatsoever, meaning it's completely possible to create a convincing, human-like imaginary friend from thin air. Goofball and Prince Charming come to mind. Luckily, the show never quite crosses into UncannyValley territory with this.
* ObfuscatingStupidity: In "Emancipation Complication", Madame Foster feigns obliviousness to how evil Lil' Lincoln is so he won't realize her plan to take him down.
* OcularGushers: Eduardo often cries an assload of tears whenever he sobs.
* OffscreenMomentOfAwesome:
** Invoked as a subtle gag in "Neighbor Pains."
--> '''Mr. Herriman''': "So, you wish to adopt Time-Travelling Tina. We shall sorely miss the [[PaintingTheMedium many fantastic weekly adventures]] we took with her through time..." ({{Beat}}) "But such is life!"
** Note that the show, which had a new episode weekly, never featured anything of the sort - the joke there is on the audience.
** Meta Example: Candy Milo revealed in an interview that Coco's lines were never written as "Coco". She was given dialogue in the script and told to just read it as "coco". Meaning, somewhere out there are written translations of what it is Coco is really saying!
* OneShotCharacter:
** Uncle Pockets only had one major appearence in ''Bloo Done It''. After this he would only get a few {{Call Back}}s.
** World from ''Destination Immagination'' would definitely qualify. This was his one and only appearance in the series. Though it's pretty much justified [[EleventhHourRanger seeing how it was the series finale.]]
** The infamous Bendy from ''Everyone Knows It's Bendy'' was written out of the show, after the poor reception received from the said episode.
** Terrence's imaginary friend Red from ''Seeing Red''.
** Omnizot and the Space Nut Boogies accidently Imagined by Goo in ''Make Believe It or Not''.
** Imaginary Man and Nemesis from ''Challenge of the Super Friends''.
** There's also Ivan from ''Sight for Sore Eyes''. The many clones of Bloo from ''Bloo's Brothers'' also qualify.
** Lil' Lincoln and his au pair Moose from ''Emancipation Complication''.
* OneWingedAngel: World, [[TheWoobie an emotional unstable]] RealityWarper, does this when Herriman threatens to leave him locked in his trunk alone again. He goes absolutely berserk and creates a chimera body for himself to destroy the ones who are trying to take Frankie away from him.
* OnlySaneEmployee: It's Frankie's job to keep everything from falling into chaos, much to her annoyance.
* OnlySaneMan: Mac and Frankie most of the time - in situations where one of them is joining in on the craziness, the other will tend to be the sane man. If both are being immature, one of them will probably come to their senses by the end of the episode to fill the role.
* OnOneCondition: Bloo will be prevented from getting adopted as long as Mac visits him daily.
* OperationBlank: Parodied in "Adoptcalypse Now" with "Operation Eight-legged-drop-big-purple-scaredy-cat-run-and-scramble" or, in layman's terms:
-->'''Bloo:''' We're going to drop this big spider on Edwardo, he'll freak out, and everyone will run away.
%%* OrphanedPunchline
* OurFounder: Elwood P. Dowd, of ''Harvey'' fame, appropriately enough. The Home itself also has a bust of its founder, Madame Foster, which Bloo promptly... [[IncrediblyLamePun busts.]]
* OutOfFocus: Most of the human supporting characters -- Goo, Terrance and Mac's mom -- are largely absent in seasons 5 and 6.
* OvenLogic: When Bloo is forced to make cookies alone in "Cookie Dough," his attempt to apply this blows up the kitchen.
%%* OverlyLongGag
* OverlyLongHug: When [[spoiler:Madam Foster steals tickets to Europe from Mac]], she does it by hugging him tightly for a good few seconds. Mac is honestly very weirded out by it and quickly leaves when Madam Foster lets go.
* OvershadowedByAwesome: Somewhat. The show's three-year involvement in the UsefulNotes/MacysThanksgivingDayParade is somewhat neat, since they're one of four Creator/CartoonNetwork shows to be represented there[[note]]the other three are ''WesternAnimation/DextersLaboratory'', ''WesternAnimation/HiHiPuffyAmiYumi'', and ''WesternAnimation/AdventureTime''. The first and last shows mentioned got balloons of their main characters, while ''Puffy'' got a float one year before the ''Foster's'' float debuted[[/note]]. [[https://www.youtube.com/watch?v=rCXADbofG2g Their float is rather nifty as well, with its combination of animatronics and puppets]]. But the float's last appearance in 2008 is... [[JustForFun/RickRoll quite remarkable indeed]].
* PaintballEpisode: "Better Off Ed" features the Bloo vs. the Babies indoor paintball battle royal.
* PaperPeople: Duchess is made of paper, befitting somebody who looks like a Picasso.
* ParentalBonus: A fair lot of it. In particular, Mac waking up next to Cheese and having to explain his "mistake" to Bloo is played a lot like marital infidelity.
* ParentalObliviousness: Mac's mom has no idea that he still goes to Foster's every day to visit Bloo. Though maybe she knows, considering Terrence could have easily told her by now, but lets him do it because it has more positives than negatives.
* PassThePopcorn: In "Challenge of the Superfriends", Eduardo is eating cereal when Bloo ties his bib around his neck as a superhero cape... while Eduardo is still wearing it! Thus Eduardo is dragged along for the plot, still eating his bowl of cereal as he witnesses the action unfold before him.
* PerpetualPoverty: It may not look it, but some parts show that, being a nonprofit organization with tons of tenants, finances are relatively low. It's pretty telling that Herriman only allows two sheets of toilet paper when going to the bathroom.
%%* ThePlan: ''I Only Have Surprise For You''.
* PokemonSpeak: Coco can only say her own name.
* PortraitPaintingPeephole: In "Room with a Feud", Bloo at one point spies on Peanut Butter by looking through eyeholes on a poster of a basketball player.
* PottyEmergency: Mr. Harriman prevents Bloo from going to the bathroom in "Busted" through forcing him to follow a series of increasingly inane rules. Bloo finally interrupts him: "GOTTA GO GOTTA GO GOTTA GO GOTTA GO GOTTA GO GOTTA GO!"
* POVSequel: "The Little Peas" is a follow-up to the episode "The Big Cheese" that shows the events of the episode from the perspective of a really tiny imaginary friend named Peas.
* PoorCommunicationKills: Several of the episodes issues could have been avoided simply by answering either Mac or Bloos questions. For example in the "Secret Door" episode everyone absolutely REFUSES to tell Bloo whats behind the mysterious door in the house (although Bloo has the right to know as a resident, and the only one who doesnt know at that), which results in his curiosity getting the better of him and opening it. In another episode no one wants to talk about why everyone aside from Frankie and Madam Foster is missing from the annual house photo resulting in Mac and Bloo spending the whole episode to find out for themselves. In one episode when Bloo asks Mac what he is preparing for Mac acts scared and tells him he wouldnt understand, this leads Bloo to incorrectly assume that Mac's getting married which results in him confusing and driving Mac away and ruining his cousins wedding (Mac was actually just the ring bearer).
* PrecociousCrush: 8-year-old Mac has a crush on 22-year-old Frankie.
* PrimaDonnaDirector: Bloo turns into one of these when he is partnered with Mac to produce a film for a contest. He constantly orders the cast around and spends their entire assigned budget on a megaphone. He ends up hiring a very famous and expensive actor (who is mentioned by name), but inverts ShootTheMoney by casting him in a role where his face is completely covered by a helmet.
* ProperlyParanoid: In "Something Old, Something Bloo", Madame Foster believes the old folks home brainwashes the senior citizens that are kept there. At the end of the episode, she turns out to be right when one of the orderlies admits that mind-altering drugs are used in the pudding they feed them.
* PunBasedTitle: Most, if not all, the episode titles are puns of some kind. Examples include:
** "[[Franchise/ANightmareOnElmStreet Nightmare on Wilson Way]]"
** "[[Literature/GoneWithTheWind Frankie My Dear]]"
** "Something Old Something Bloo"
** "Bad Dare Day"
** "Crime After Crime"
* PunnyName: [[GrumpyOldMan Iman Oldcoot]], [[WesternAnimation/TheIronGiant Myron Giant]], Sam Burger, Nemesis[[spoiler:ter]], Jimmy Shoes, [[Creator/BillyBobThornton Belly Bob Norton]], plus many others.
* QuicksandSucks: Wilt ends up sinking in quicksand in "Camp Keep A Goof Mac Down".
* QuietCryForHelp: In "The Sweet Stench of Success", Bloo is tricked into signing himself into indentured servitude after he hits it big as a corporate mascot, and being locked away by his greedy agent Kip Snip. As a last resort, [[EveryoneKnowsMorse he tap dances "HELP ME MAC" in Morse code during a live performance.]]
* QuirkyHousehold: The titular foster home is full of quite a lot of eccentric and bizarre imaginary friends.
* RaincoatOfHorror: There was a horror-themed episode taking place on a rainy night, where a forbidding-looking character with a hook-hand, wearing a concealing raincoat seems to be following Frankie around. [[spoiler: He's actually a goofy-looking imaginary friend looking for a place to stay, and he's following Frankie because he heard about Foster's.]]
* RealityWarper: Goo has an overactive imagination, which means that she runs the risk of calling new Imaginary Friends into existence by accident (and somehow, she manages not to be creepy). Frankie's new friend, World, controls an entire dimension inside a toy box.
* RealTrailerFakeMovie: To Bloo's movie in "One False Movie"
%%* RearWindowInvestigation
* RebelRelaxation: James Withazee from "Bye Bye Nerdy" is shown leaning against walls and such as part of his "cool" mannerisms.
* RedOniBlueOni: Bloo and Mac. ''Not'' ColorCodedForYourConvenience as Mac is always wearing a red shirt and Bloo is... well... [[ExactlyWhatItSaysOnTheTin blue]].
* RepeatingSoTheAudienceCanHear: The only reason we know what Coco's saying.
%%* RepeatWhatYouJustSaid
* ReusedCharacterDesign: The design for Dexter's Dad from "Glove at First Sight" in ''WesternAnimation/DextersLaboratory'', also re-used for Dick Hardly in ''WesternAnimation/ThePowerpuffGirls'', is re-used for Kip Snip in "The Sweet Stench of Success", although it's had some changes [[https://imgur.com/a/xjtJKbV as shown here]].
* RhymesOnADime: Uncle Pockets constantly speaks in rhyme.

* ElevatorFloorAnnouncement: In "Squeeze the Day", Bloo does this on their way upstairs as they stop at every floor(after he pushed all the elevator buttons).
* EarnYourHappyEnding: Frankie and World in "WesternAnimation/DestinationImagination." Frankie finally gets what she wanted all along, to be treated fairly and respected for all she does, Mr. Herriman finally fairly splitting the house work among everyone in the House instead of all on her. World, the BigBad of the movie and an emotionally unstable RealityWarper whose been sealed in a toy chest by himself for who knows how long, is finally freed from his prison and has the friends he'd wanted the entire movie. But both had to go a long way to get it.
* EarlyInstallmentWeirdness: The "House of Bloo's" pilot contains many major differences from the main series. To wit...
** Bloo was slightly mischievous, but still a very nice guy. In fact, the other characters constantly describe him as "a lovable imaginary friend". This comes as a shock to anyone used to the rude, egotistical, and borderline sociopathic Bloo in the later episodes.
** Only a select few characters could understand Coco. In fact, Mac somehow being able to understand her, much to Mr. Herriman's surprise, was a major indication of how intelligent he was for his age. In later episodes, ''anyone'' could understand her, even if they had just met her.
** Duchess was an outright villain, willing to ''kill'' Bloo, instead of the simple RoyalBrat she is in the main series.
** Madame Foster was depicted as having a hard time going down the stairs and traversing the hallways due to her age, which is why she doesn't even physically appear until the end, with her saying that it took her that whole time to walk down. In the later episodes, she becomes a surprisingly agile CoolOldLady.
** Eduardo speaks a lot more GratuitousSpanish than in the later episodes, to the point where Wilt had to translate both him ''and'' Coco when saying good night to him.
* ElectionDayEpisode: In the episode "Setting a President", Frankie challenges Mr. Herriman for the position of house manager, and they hold an election. Bloo briefly posts himself as a candidate (mostly for the attention), and after coming last on the polls, becomes Herriman's campaign manager.
* EmbarrassingOldPhoto: Turns up in "Infernal Slumber" when Eduardo finds a picture of Mac as a baby bathing in the sink with his butt visible and decides to photograph the picture against Mac's wishes.
* EmotionallyTongueTied: Wilt has trouble saying "No" when someone asks him to do something.
* EndOfSeriesAwareness: In the final episode, when Bloo finds out Mac is moving, he tries to convince him to stay by listing things they can do, all of which were the plots of previous episodes. When Mac tells him they've done all those things already, Bloo says that if they've done everything, the only thing left is to jump the shark. The episode also ends with the opening scene of Foster's being drawn played in reversed, almost like it's being erased.
* EpisodeTitleCard: All the episodes have these, typically with a relevant sound effect over it. We only see the episode's title in this, as writing, directing, etc. credits are typically played over the first few minutes of the episode.
* EthnicScrappy: Eurotrish is one InUniverse: she sings off-key, has a questionable design and voice and was rejected by her creators who found her annoying. However, PoesLaw is certainly in effect.
* EveryoneHasStandards: In "Eddie Monster", the Imaginary Friend fighting ring allows -- even encourages -- [[CombatPragmatist cheap shots and dirty tricks]]. However, attempting to fix a fight is grounds for immediate disqualification.
* EveryoneIsGoneEpisode: Squeeze The Day's plot revolves around this idea. Mac and Bloo are the only ones who aren't gone, time for some fun.
* EveryoneKnowsMorse: Bloo tap dances Morse code to call for help in "The Sweet Stench of Success".
* EvilCounterpart: [[SubvertedTrope Subverted]] in an episode Terrence attempts to make his own imaginary friend to deal with Bloo, who constantly manages to humiliate and outsmart him whenever he starts picking on Mac. Not only is he sqaure in contrast to Bloo's round, blob like appearance, he's red and, [[SarcasmMode surprisingly]], named Red. It's Subverted though in that, despite being made to be an EvilCounterpart to take on Bloo, Bloo easily outsmarts and humiliates him at every turn, and once he begins to realize Red isn't that bad a guy after he pushes his pranks too far, offers to be friends with him. Red quickly realizes that GoodFeelsGood and starts going after ''[[HoistByHisOwnPetard Terrence]]'' for picking on Mac. All in all, he's arguably a nicer imaginary friend than Bloo himself!
* ExactWords: When Mac and Bloo get lost in the house in "Dinner is Swerved", they end up asking Duchess if she can help them. She says she can, but when she doesn't lift a finger to, she clarifies that they asked if she ''could'' and she can. They didn't ask if she ''would'' and she won't.
** In "Cheese a Go-Go", Coco and Jackie befriend a cop and go get sandwiches. One of them gives the cop a black eye and they both wind up in jail. To be fair, Jackie said "Let's go get sandwiches". He ''didn't'' say "I'm buying you a sandwich".
* ExpospeakGag: Mr. Herriman's preferred manner of speaking quite often involves using technical words to describe even the most mundane and simplest of phrases.
* {{Expy}}:
** Mac is based on a one-time ''WesternAnimation/ThePowerpuffGirls'' character, Mike, who had an imaginary friend of his own.
%%** Mac's mother shares a lot of similarities with [[WesternAnimation/ThePowerpuffGirls Ms. Bellum]].
%%** Frit and Frat are basically G-Rated versions of WesternAnimation/BeavisAndButthead.
%%** Lil' Lincoln's au pair Moose, from ''Emancipation Complication'', is one of [[WesternAnimation/ThePowerpuffGirls Big Billy]].
* ExtranormalInstitute: Foster's is a place where human kids adopt imaginary friends.
* TheFaceless: Mac and Terrence's mom. At most, we see the back of her head, if we see her head at all.
* {{Fainting}}: Happens to several characters at the end of "Bloooo." Frankie, who has been desperately trying to get back into the house which Wilt and Ed boarded up in a panic, finally drives the bus through the front door. Shakily stepping out of it while muttering about a monster she believes has been stalking her, she passes out upon seeing Ed, Wilt, Coco, and Mr. Herriman coated in the dust she kicked up when crashing through the doors, believing them to be ghosts. They themselves faint when the "monster" that was stalking Frankie enters, only for it to be revealed as an imaginary friend trying to get housing. When he sees Bloo, turned pale-white due to illness, he mistakes him for a ghost and runs away screaming.
* FantasticRacism: It's never really explored in the series but there is a lot of evidence to suggest that imaginary friends suffer from notable discrimination. They are seemingly seen as being nothing but glorified playmates for children and once a child matures they're expected to abandon their friend, with Foster's existing to house friends with nowhere to go. They also appear have less rights than normal people as they're not allowed some jobs, adopted friends are shown to be legally subordinate to the whims of their adopters and some areas have outright bans on imaginary friends living within their limits.
* FantasticScience: Figmentology, the study of imaginary friends, as alluded to in "Good Wilt Hunting".
* FantasyKitchenSink, as well as FairytaleMotifs: Unicorns, giant monsters, superheroes, and countless other creatures.
* FashionableAsymmetry: Wilt, who is missing an arm and has one of his eyes being wonky and on a crooked eyestalk.
* FawltyTowersPlot: "Bus The Two Of Us," which involves Bloo taking the Foster's Bus on a joyride and Mac, who got dragged along, asking Wilt to keep this fact under wraps, requiring him to lie which, for a NiceGuy like him, is far from an easy task.
* FieryRedhead: Frankie, as Mr. Herriman and Bloo learn when they push her too far. Or as Dylan finds out when he threatens her friends.
* FirstNameUltimatum: And justified in the cases of some characters, like Mac, who well, [[NoFullNameGiven don't have a last name]].
* {{Flanderization}}:
** Bloo wasn't ''nearly'' as much of a jerk in the early seasons.
** The whole series could actually count in regards to how nastier it got in tone in the later seasons. While the first two seasons had their share of sadistic and mean-spirited moments (such as the infamous "Everyone Knows It's Bendy"), it was still a mostly lighthearted show. By the third season, while there are still some lighthearted episodes, there are far more moments of sadism and cruelty with even the most good-natured characters like Mac and Wilt suddenly [[TookALevelInJerkass turning into a jackass]] [[DependingOnTheWriter if the plot demands it]].
* FleaEpisode: "Land of the Flea", where Eduardo picks up fleas from his pet dog, Chewy, befriends them, and protects them from Frankie and Mr. Herriman. Bloo, thinking that having fleas sounds like fun, makes a robe from Eduardo's fur. The fleas turn out be imaginary friends themselves, and thus are allowed to stay. Frankie and the imaginary friends shave all the fur off the furry imaginary friends and make a special room for the fleas.
* ForbiddenFruit: In "The Trouble With Scribbles" when Bloo finds the door behind which the titular Scribbles are kept. His curiosity is ignited by Mr. Herriman mentioning "Deep, dark, mysterious secrets" when explaining why the door should remain shut and fueled by everyone else avoiding talking about it whenever he asks. Eventually he can't take it anymore and sneaks off at night to open it.
* FramedClue: How Mac and Bloo find the map to the Foster's treasure in "Squeeze the Day" following a failed attempt to use a picture of Madame Foster as an impromptu cookie sheet to slide down the stairs with, breaking it and revealing the map.
* FreudianTrio: Mac (Superego), Frankie (Ego) and Bloo (Id) had this dynamic in most of their interactions.
* FriendlyTickleTorture: In the episode "Bloo Tube" as one of the videos, Frankie and another imaginary friend do this to an elephant to make him shoot milk out of his nose and ears.
* FunWithHomophones:
** In "Crime After Crime", Coco steals Mr. Herriman's carrots, so he calls the police reporting a theft of a hundred carrots. The cops, not knowing he's a [[StockAnimalDiet rabbit]], believe that he said a hundred ''karats''; i.e., that Herriman had called to report that a large amount of jewelry was stolen. [[HoistByHisOwnPetard This ends up getting Herriman arrested when the cops arrive at Foster's and see him holding some jewelry.]]
** In "Affairweather Friends", Berri tries to steal Bloo from Mac by disguising herself as a rich kid named Barry. Because of the similar-sounding names, Mac's unable to explain to Bloo that the two are one and the same until he refers to Berri as "Heather" (which was one of the [[AccidentalMisnaming incorrect names Bloo used to refer to Berri]] [[CallBack in her debut episode]]).
* GenkiGirl: Goo, complete with MotorMouth And possibly Madame Foster and Coco.
* GentleGiant: Eduardo is a giant purple minotaur who appears frightening to Mac at first, but he turns out to be sweet and (to be honest) a coward - [[BerserkButton unless his friends are in danger]]. Wilt is a very, very tall fellow with one arm who is polite to the point of neurosis.
* GodivaHair: In "Camp Keep A Good Mac Down", Madame Foster is shown to easily adapt to the wild and it gets to the point that she starts going around naked. Because this is a children's show, her nudity is covered up by her hair being worn down.
* GoshDangItToHeck: Frankie. "Holy. Guac. Amolie."
* GrandFinale: ''Destination: Imagination'' and "Goodbye to Bloo". Depending on your views, you might assign either the last episode or the movie as the true finale. "Goodbye to Bloo" essentially brings up the point that started the series in the first place -- Mac having to say goodbye to Bloo for good. Through classic shenanigans, it becomes a huge misunderstanding that Mac and family will move away and leave Bloo up for adoption. In the end, it's strongly disproved... and ''Cheese'' ends up being sent to live at Foster's, followed by a thank you note to the viewers in the credits. The movie, on the other hand, ends with all the friends at Foster's jumping into the toy box, Mac and Bloo the last ones in, which gives a nice closing shot that basically says the characters are going away now, back into the toy box like stuffed animals -- say your goodbyes.
* GrandmasRecipe: In the episode, "Cookie Dough", Madame Foster has a special recipe for cookies that she only makes once a year. Bloo takes the recipe and starts making the cookies for profit, but they quickly fail to sell, because Madame Foster had a {{secret ingredient}} that he forgot: love.
* GRatedDrug:
** Sugar to Mac. Just a small amount causes him to go into a hyperactive frenzy of devouring anything sweet he can find.
** In "Cookie Dough" Frankie's obsession with Madame Foster's cookies is blatantly akin to a cocaine addiction.
* GratuitousSpanish: Eduardo. He often throws in various words and calls Bloo "Azul".
* GreetingGestureConfusion: In the episode "I Only Have Surprise for You", [[ItMakesSenseInContext when Mr. Herriman's back-up team to set up a birthday party that Mac is trying to prevent succeeds in their mission]], the back-up team leader offers Mr. Herriman a high-five but Mr. Herriman shakes his hand while his hand is still in the air for the high-five.
* GrowingUpSucks: The premise is that nearly all kids grow out of needing their imaginary friends, so Mac will likely end up leaving Bloo. [[AvertedTrope However]], we've seen some creators as adults, and they still care a great deal for their imaginary friends. Madame Foster says that Mac's imagination is the purest she's seen since her own, and ''she'' never gave up ''her'' imaginary friend...
** Perfectly summed up by Frankie at the end of ''Squeeze the Day.''
-->'''Frankie:''' ""I wish I could be you, Mac. No job, no responsibilities. You will never be a child again. Don't let it pass you by. All that matters is right here, right now. Take advantage of every precious moment. This is your time to do the most awesome of awesome things."
* GrumpyOldMan: Old Man Rivers from ''Neighbor Pains'' and the [[MeaningfulName (appropriately]] [[PunnyName named)]] Iman Oldcoot from ''Something Old Something Bloo''.
* HairRaisingHare: Normally strict and formal with the appearance of a distinguished gentleman, you do NOT want to make Mr. Herriman angry. Even Frankie cowers in fear when Herriman truly has his BerserkButton pressed as seen in "World Wide Wabbit".
* HalfDressedCartoonAnimal: [[LampshadeHanging Lampshaded]] in "Adoptcalypse Now;" while Mac claims to Mr. Herriman that he's bringing Coco in because she's embarrassed about being nude(he's really trying to avoid her being adopted), Herriman points out that most imaginary friends are nude. Mac calls him "Pantsless Joe" in response, prompting Herriman to [[HandOrObjectUnderwear cover his (offscreen) crotch.]] He's seen wearing a pair of overalls the rest of the episode.
* HandsOffParenting: Goo's unseen parents. They let her chose her own name as a baby and have no qualms about Goo spontaneously creating dozens of imaginary friends on the spot.
* HandyFeet: Coco is an ArmlessBiped and as such, often uses her feet for most tasks.
%%* HangingJudge: "Go Cheese Go".
* HerCodeNameWasMarySue: "The Bloo Superdude and the Potato of Power" had Bloo tell a story where he painted himself as an overpowered and muscular badass.
* HeterosexualLifePartners: Mac and Bloo, which is particularly funny in "Mac Daddy", when they discuss Mac's creation of Cheese as if Mac cheated on Bloo.
* HiccupHijinks: The premise of "Hiccy-Burp;" Bloo gets the hiccups before an imaginary friends beauty pageant and he and Mac initially think he'll be unable to perform if they can't get rid of them, but they end up finding a way to use it in the "Talent" portion of the contest.
* HighClassGlass: Mr. Herriman's monocle.
%%* HornyScientist
* HorribleCampingTrip: In "Camp Keep a Good Mac Down," Bloo [[BigEater eats all the food that he and his friends brought while en route to the campsite]], everyone else struggles to find food in the wild to last the weekend.
* HugAndComment: "Mac Daddy" has:
-->'''Bloo''': I love you, brother! ''(hugs Cheese)''\\
'''Cheese''': I pooted.
* HumansAreUgly: Duchess considers Frankie ugly. Then again, [[HypocriticalHumor she considers anyone who isn't herself ugly]].
* HumanMail: Bloo tries to send Cheese away through the mail. Cheese gets sent back due to insufficient postage -- the message on the package says "Postage insufficient to tolerate smell".
* INeverSaidItWasPoison: Bloo once Jackie Khones found Madame Foster's favorite doily in comic book story "Penny Saved".
-->'''Bloo:''' I wonder how that got shoved under the squeaky top stair?
-->'''Jackie:''' Hey! How did you know it was under the squeaky top stair?
-->'''Bloo:''' Lucky guess?
* IdeaBulb: Spoofed in "Cookie Dough;" When Bloo is thinking of an idea to raise money for Foster's to buy a new roof when their current one is leaking, a light bulb imaginary friend hovers over his head, to Bloo's annoyance.
* IdenticalGrandson: Frankie looks exactly like photos of a young Madame Foster, and both wear green hoodies and purple skirts.
%%* IHaveBrothers
* IKnowYouKnowIKnow: Done in "Affairweather Friends" when Mac figures out that the rich kid Barry is actually Berry in disguise and ends up falling into a trap, after which Berry goes on a lengthy speech about anticipating that Mac anticipated her scheme and that she knew what he and Bloo would try to do.
* ImaginaryFriend: Well, [[ExactlyWhatItSaysOnTheTin obviously]]. The twist here is that the friends kids imagine actually become real, and come to Foster's when their kids outgrow them. Lampshaded in "My So-called wife" where Mr. Herriman explains this twist to a visitor who thinks imaginary friends are only visible to their creators.
* InAWorld: Parodied in "One False Movie;" this is how Bloo starts the movie he made for Mac's school's film festival
-->'''Bloo:''' ''(Voiceover)'' In a world where chaos reigns [[{{Metaphorgotten}} like cats and dogs in a hailstorm...]]
* IncrediblyLamePun:
** From the pilot movie: "Let's Bloo (do) this!". [[LampshadeHanging The gang even reacts to this.]]
** Done several times in "Mac Daddy": Mac and Cheese, Bloo Cheese, and finally "Cheese Louise". Cue Mac's FacePalm.
* InsaneProprietor: Madame Foster is a little more than eccentric, but she does keep the house running, despite her quirks and the general craziness around her.
* InsultBackfire: Duchess keeps on trying to insult the Applebees in "Duchess of Wails", but they all assume that her crass remarks and sarcastic comments are supposed to be jokes.
* InstantWebHit: The "Funny Bunny" video in "World Wide Wabbit".
* IntentionalMessMaking:
** One episode has Bloo doing everything he can to be [[DeniedFoodAsPunishment sent to bed without supper]]. The first we see of him doing this is "decorating" a couch with ketchup and mustard. He fails; Herriman sends everyone ''but'' Bloo to bed without dinner as he believes everyone is spying on him and Bloo is exposing the culprits, and Bloo is made to eat the dinner he is trying to avoid as delayed punishment. ''All'' of it.
** In "Everyone Knows It's Bendy", the eponymous Bendy smashes a vase, eats chips while leaving crumbs on the floor, covers Wilt's shoes in mud to get the floor muddy too, breaks a window with a baseball, and writes on the walls. He [[KarmaHoudini gets away with it]] by [[CrocodileTears fake-crying]] and [[WoundedGazelleGambit playing the victim card to blame the other imaginary friends]].
* IntergenerationalFriendship: 22-year-old Frankie and 8-year-old Mac.
* InterruptedCooldownHug: Happens during ''Destination Imagination''. [[spoiler:Frankie had just calmed World down and made him friendly towards her friends when Mr. Herriman comes barging in and basically reinforces every one of his fears in one fell swoop before attempting to push everyone out of the toy chest. Cue the UnstoppableRage that literally tears the entire reality of the toy chest apart.]]
* InterspeciesRomance: Coco briefly pursues a relationship with a yeti in "Mondo Coco".
* IntoxicationEnsues: Mac on sugar, to the point of tearing off his clothes and running naked through the town.
* InvisibleCelebrityGuest: Mel Gibson and Tom Hanks appeared with buckets on their heads.
* IronicName: There is one imaginary friend named Crackers who doesn't like crackers, according to her trading card. She can't be blamed considering sharing her name with the snack is the reason why people who expect the real deal don't adopt her, as happened in "Mac Daddy".
* IrritationNightmare: In the episode "Mac Daddy", Bloo has a nightmare involving a crossdressing {{C|loudcuckoolander}}heese ruining a fantasy moment saying, "I'm a lady!", then kissing Bloo and saying, "Now we're brother ladies!"
* ItsASmallNetAfterAll: Averted in "World Wide Wabbit." After finding out a video of him is popular on the internet, Herriman tries throwing out the computer, but Frankie explains to him that's not how it works.
* JumpingTheShark: [[invoked]]Referenced in a ShowWithinAShow and was literally attempted by Bloo in the GrandFinale.
* KavorkaMan: Bloo gets attention from Berry even though he's not exactly handsome and a real jerk. Her being completely insane might have something to do with it.
* KazoosMeanSilliness: The music is played with children's instruments, including kazoos, appropriate for a show about kids' {{Imaginary Friend}}s. Furthermore, main character Bloo has the full name Blooregard Q. '''Kazoo'''.
* KillerRabbit: Several of the imaginary friends may look cute, but can be very dangerous.
* KryptoniteIsEverywhere: [[FlyingBrick Imaginary Man]] may seem tough, but all you have to do to make him lose his powers is to throw flowers at him. Not that his designated ArchEnemy, [[DarkActionGirl Nemesister]], has it any easier. She loses her powers once you rough up her perfect hair a little.
* LackOfImagination: Addressed when Wilt gives Mac and Bloo a tour, he points out an imaginary friend that is [[ShoutOut an exact copy]] of Mojo Jojo from ''WesternAnimation/ThePowerpuffGirls'' saying that some kids just copy what they see on the TV.
* LampshadedDoubleEntendre: Subverted in "Partying is Such Sweet Soree"
-->'''Bloo:''' ''(Describing the party to Mac)'' ...and on the 6th floor, "Ring Around the Rosie" ''(suggestively, elbowing Mac)'' If you know what I mean!
-->'''Mac:''' ''(audibly confused)'' Not really...
-->'''Bloo:''' Yeah, me neither.
* LaserGuidedKarma: "A Lost Claus" has Bloo rewarded for his collective naughty shenanigans when he receives an unceremonious pile of coal for Christmas. Mac [[{{Reconstruction}} celebrates]] this because it proves Santa Claus is real if he knows Bloo so well to give him coal.
%%* LawOfDisproportionateResponse
%%* LawyerFriendlyCameo
* LearnedFromTheNews: In "World Wide Wabbit", the friends try to keep Mr. Herriman from finding out that Bloo secretly recorded him doing a dance for Madame Foster, released the footage onto the Internet and is now viral. When Frankie sees a picture of Herriman in the newspaper, a game of KeepAway ensues to prevent him from seeing it; eventually, Eduardo [[EatTheEvidence eats the paper]] and Wilt suggests that he watch the news on TV. Unfortunately, the station's news team is in front of the house to do an interview -- ''and they're live!''
%%* LegCling: Parodied in "Imagination Invaders", by Bloo of course. [HOW?]
* LessonsInSophistication: In "My So Called Wife", Mr. Herriman has to teach [[CloudCuckoolander Coco]] how to behave like a lady when a rich benefactor thought that she was his wife and the two were invited into his mansion for the charity. [[ItMakesSenseInContext All the while, Mac teaches Bloo what sarcasm means]].
* LetsMeetTheMeat: Food-based imaginary friends are shown in the episode "Dinner is Swerved," usually imagined by kids in diet camps according to the chicken leg friend we see.
* LimitedWardrobe: The human characters always wear the same clothes, as do the few imaginary friends who actually ''wear'' clothes. "Setting a President" features a bit of LampshadeHanging; When Frankie runs against Mr. Herriman for president of the house, Herriman eventually resorts to a smear campaign in his efforts to win. One of the resulting ads counters Frankie's promises of "change" by pointing out that she wears the same green jacket every day.
* LivingProp: Most of the friends do little more than stand in the background.
* LoadsAndLoadsOfCharacters: Ther are quite a lot of imaginary friends on this show.
* LoopholeAbuse: In "Beat with a Schtick" Bloo intentionally gets himself in a lot of trouble hoping to get expelled. Why? He is about to get into a fight with the new guy (to quote Mr. Herriman: "That vicious, gargantuan bone-crusher"). Mr. Herriman [[CurbStompBattle does the math]] and decides this isn't an illegal fight but a "gentleman's challenge" which is totally legal.
* LoveMakesYouCrazy[=/=]LoveMakesYouEvil: Berry attempts to ''kill Mac'' in both appearances because she thought he was getting in the way of her relationship with Bloo.

* TwoDVisualsThreeDEffects: Spoofed in "One False Movie" with the CGI Eduardo in Bloo's movie.
* AbsenteeActor:
** Mac doesn't appear in "Pranks for Nothing", even in the beginning. The events right at the beginning took place right after he left, or he was sick and couldn't come to Foster's anyway. It also could have been ''before'' he even came, considering that Mr. Herriman said the trip would be 7 hours long.
-->'''Bloo''': Hey, Mr. Herriman! How long till we get there?
-->'''Mr. Herriman''': 7 hours.
** Mac similarly does not appear in the comic book story "Block Rockin' Feats" (Cartoon Network Block Party #35).
* AccentAdaptation: Hispanic imaginary friend Eduardo has a US accent in the Spanish dub.
* AccidentalMisnaming: Bloo constantly forgetting Berry's name in "Berry Scary." He does, however, remember her as "Heather."
-->'''Berry:''' '''''MY NAME IS BERRY!!!'''''
* AcquaintedWithEmergencyServices: In Season 2, "My So Called Wife", Mac, Bloo, Coco, Mr. Herriman, and several other people are thrown in jail for a night after a phony benefactor threw a fake gala in someone's mansion without permission and the owner has everyone arrested for trespassing. Everyone was released from jail in the morning leading to Bloo saying goodbye to the police officer.
-->'''Mac''': What a crazy night.\\
'''Bloo''': Eh. I had worse. ''(to a police officer)'' Good seeing you again, Charles. Say hi to the kids for me.\\
'''Charles''': Will do, Bloo.
%%* AcquiredSituationalNarcissism
* AdBreakDoubleTake: In "Foster's Goes to Europe"...
-->'''Wilt''': The spark plugs are gone!
-->'''Mac''': What does that mean?
-->'''Wilt''': Somebody sabotaged the bus.
-->*fade to commercial*
-->'''Wilt''': Somebody sabotaged the bus!
* AdoptAServant: When Bloo signs up with a producer be a spokesperson for a deodorant product, he finds out that the documents were actually adoption papers and that the PrimaDonnaDirector is now his legal guardian.
* AdoptiveNameChange: In the pilot episode, a girl wants to adopt Bloo and name him Tiffany (since she believes Bloo is a girl).
* AnAesop:
** "Where There's a Wilt, There's a Way" carries the obvious but nonetheless important message that feeling obligated to do people favors can and will land you into unwanted positions, and it shouldn't hurt to say "no" to people.
** "Sweet Stench of Success" shows that you really should be happy with what you have in life, and to be careful what you wish for.
* AffectionateParody:
** [[PunnyName Eurotrish]] is a spoof of [[WesternAnimation/AnAmericanTail Tanya Mousekewitz]].
** Morsey is a parody of Morissey, fitting in with the 80s allusions.
** The unleashed Extremeosaur in the movie is a parody of Pac-Man.
* AlienGeometries: Foster's itself, as proven by the episode "Dinner is Swerved". At one point, Mac even opens a door that leads to an oncoming train, then nonchalantly closes it, with the train never once making contact with the door!
* AlliterativeName: Francis 'Frankie' Foster.
%%* AllOfTheOtherReindeer: Poor Wilt...
* AllThereInTheManual: The first season DVD feature "Gallery of Friends" reveals some of the names of the one off and background imaginary friends.
* AmateurFilmMakingPlot: In "One False Movie", the school principal is impressed with Mac's film about Foster's (which Bloo added armpit fart sound effects into) and enters Mac to represent his school in the Annual State-wide Elementary School film festival. He gives Mac a $500 budget and the idea for the film, which Bloo helps make into a movie called "T-Rex-A-Tron Alien Wolf III: A Prequel In Time: The Unrelenting". Despite all the extra effort and money Bloo puts into the film[[note]]which includes having Creator/TomHanks play a robot and a [=CGi=] Eduardo when the real one refused to be involved with the project, which Mac had to pay for by selling his Space Wars action figure collection and Madame Foster's antiques (which she unknowingly bought back anyway)[[/note]], the ending to Bloo's movie gets taped over by an episode of ''[[WesternAnimation/DoraTheExplorer Lauren is Explorin']]'' that Eduardo was trying to watch, causing Bloo's film to lose.
* AnnoyingBackgroundEvent: In "Mac Daddy", Mac and Bloo discuss what to do about Cheese, while Cheese is playing with a toy horse just off frame. Eventually, Bloo gets sick of Cheese's horse and yells at him to cut it out.
* AnthropomorphicFood:
** The food friends, who were apparently imagined by hungry children at a weight-loss camp.
** At one point Mac's brother imagines up a pizza friend. And then promptly ate it.
* AntiquatedLinguistics: Everything Mr. Herriman says is in archaic and old-fashioned terminology.
* ApologisesALot: Wilt. "Oh! I'm sorry, is that okay? I'm sorry!"
* ArbitrarySkepticism: Imaginary friends are well-known to be real, and include all kinds of monsters and other weirdness, yet Mr. Herriman seems quite certain in "Bloooo" that there are no such things as ghosts. Also, in the pilot, Bloo is clearly about to say "There's no such thing as monsters" before Wilt cuts him off.
* ArtisticLicenseGeography: Close but no cigar, Mac: counter to his statement in "Duchess of Wails", UsefulNotes/{{Singapore}} isn't ''in'' Malaysia, it is an independent county off of one of Malaysia's coasts. At least he's far closer than Terrence, who thinks Singapore is in Wisconsin.
* ArtEvolution: While relatively minor, there are some color/appearance differences in the earliest episodes, which is seen mostly in Mac and Eduardo. Also notable in season five is that Mac's height increases slightly.
* AsLongAsItSoundsForeign: Eurotrish. She's basically a relentless parody of this trope. She says she's from Europe, and seems to mean that literally... in that she wears clothes that combine stereotypes of at least six different European nationalities (Dutch clogs, a french beret, a shirt with the British flag, among other things) her accent keeps changing, and she always says she wants to go home to Europe, not to any specific country. At the end of "Foster's Goes To Europe", we see her "back home in Europe" in a little stereotypical village that could be almost anywhere. The locals promptly get fed up with her singing and throw her out, just as they did when she lived there at an earlier time.
* AspectRatioSwitch: The first four seasons were produced in 4:3, and the remaining two in 16:9.
* AttentionWhore: Bloo, who seems to think ItsAllAboutMe, and gets visibly annoyed when the others don't share his excitement in various things.
* AuthorAvatar: After the pilot premiered, Craig [=McCracken=]'s family told him Mac is pretty much what [=McCracken=] was like when he was little. His name's even "Mac".
* BabyTalk: Frankie, in "Dinner is Swerved". "I'm sowwy, Mistuh Hewwiman."
* TheBadGuyWins: The titular Bendy from "Everyone Knows It's Bendy" gets [[KarmaHoudini zero comeuppance]] for his actions.
* BalloonBelly:
** Frankie at the end of "Cookie Dough" after consuming dozens of Madame Foster's cookies.
** Coco when she rather suddenly put on weight in "The Big Picture".
* BandEpisode: "Shlock Star" is about four minor imaginary friends (Fluffer Nutter, Yogi Boo Boo, Bloppy Pants, and Billy the Squid) forming a band named Pizza Party, which Bloo tries to join, but is refused due to being less than helpful. Out of revenge for being refused ''and'' for letting Mac become the band's manager, he forms his own band named Taco Fiesta together with Wilt, Eduardo, and Coco, but they soon become their own band without Bloo.
* BattleInTheRain: Spoofed in "Duchess of Wails" when Mac and Bloo try to get Duchess back into the house.
* BeCarefulWhatYouWishFor: In the ChristmasEpisode "A Lost Claus", Bloo is dissatisfied with Foster's custom of giving out only one present to each resident every Christmas. He tries to stage a (poorly done) "Christmas Carol" scenario for Mr. Herriman in order to scare him into giving more presents for Christmas. Unfortunately, Bloo (whilst disguised as a [[MakesSenseInContext robot]]) words it in such a way that indicates little foresight on Bloo's part: "There shall be [[ExactWords not one]] present." A couple scenes later, Bloo is sheepishly calling Mac over how his wish has come true: he doesn't have to worry about only getting one present tomorrow, because Herriman ''threw out all things Christmas'' in order to take the advice to heart! So Bloo (along with every resident at Foster's) won't even get the one present. Fortunately for the other imaginary friends, Santa put things right for them by giving them their presents and [[LaserGuidedKarma gave Bloo a stocking full of coal]].
* BedsheetLadder: Attempted in "Dinner is Swerved", to get down to the dining hall. Unfortunately, the rope is too short, and Mac and Bloo bounce off the pile of mattresses they dropped and end up right back on the roof.
* BackBlocking: In the episode "Camp Keep a Good Mac Down". Eduardo does when after he swat all the bees attacking Bloo, and he reveals Bloo covered in bee stings.
* TheBet: Mr. Herrimen's condition with Mac: Bloo will be prevented from adoption as long as Mac comes to Foster's every day.
* BigBad: [[RealityWarper World]] in ''[[TheMovie Destination Imagination]]''. He's not actually evil, though, just a scared little kid who's got ''serious'' abandonment issues and just wants a friend.
* BigBadDuumvirate: Terrence and Duchess in "House of Bloo's", who team up to get rid of Bloo once and for all.
* BigBrotherBully: Terrence. "Stop! I just want to punch you!"
* BigEater:
** Bloo tends to eat a lot.
** Mac almost always averts this, except when he has ''[[GRatedDrug sugar]]'' and goes on a spree of eating anything sweet he can find.
** Frankie becomes gluttonous when she's near cookies, especially in World's cookie castle he made for her.
* BigFriendlyDog: Used in the beginning of episode 11. A couple mistakenly brings a stray dog to the house, and when Frankie opens the door she is promptly tackled and licked silly.
* BiggerOnTheInside:
** The titular building. It's so big you can get lost in it for ''days''.
** World's toy box, though that's likely due to him being a RealityWarper.
* BilingualBonus:
** In the episode ''One False Movie'' Coco's subtitles are French for "I do not speak French!".
** In ''The Bloo Superdude and the Magic Potato of Power'' in the part where Bloo accidentally starts telling a sitcom, the guy says "What was it you used to say to me? Usted huele muy mal," which is Spanish for "You smell very bad."
* BilingualDialogue: Coco only says "Coco", but everyone she speaks to seems to understand her.
* BirthdayEpisode: There were several such episodes. The birthday celebrated in those episodes were Madame Foster, Mac and Bloo.
* BirthdaySuitSurpriseParty: A flashback in "I Only Have Surprise For You" shows that Bloo once pulled a prank on Mac where a surprise party was held after he just got out of the shower.
* BittersweetEnding: The series finale is more of a HappyEnding, with [[spoiler:Mac moving to the house next door from Foster's, but [[UnpopularPopularCharacter Cheese is moving into The House.]] Out of universe, we have the gutwrenching last few seconds of the episode, as the theme plays in reverse and the house is erased out of existence, like the series itself is saying goodbye. It's common for people who grew up with the series to admit that it made them cry.]]
* {{Bizarrchitecture}}: The titular Home. It looks odd enough from the outside, but it's full of AlienGeometries and ChaosArchitecture inside. Showcased early on in "Dinner is Swerved" (Mac and Bloo arrive on the roof: "But... we went ''down''!") and "Bloooo" (Bloo ascends an impossibly long, spindly, unsupported staircase to get to his room).
* BlackComedy:
** In one episode, Terrence imagines a living slice of pizza with eyes and a mouth. It only has a single line, that being a child-like "I love you" directed at its creator, followed by screams of terror as the boy snatches it and starts taking bites out of the poor thing's body. It's probably the only death scene in the whole run of the show, and it's entirely PlayedForLaughs.
** In the last episode, Bloo's first idea to prevent Mac from moving away was to '''kill him.'''
* BlindBlackGuy: STEEVIIIIIIIIIIIIIIIIIIIIEEEEEEEEEEEEEEEEE!!
%%* {{Blipvert}}
%%* BMovie
* BookEnds: The opening intro to the series starts with the world of Foster's being drawn out in pencil line-art until it changes to color with a calliope theme in the background. At the end of the TV finale, "Goodbye to Bloo," the world of Foster's is essentially un-drawn and the calliope theme plays backwards.
* BornAsAnAdult: The show's very premise is that imaginary friends come to life the instant they are created, so of course many imaginary friends have had adult forms for as long as they've been alive.
* BrattyHalfPint: Bloo.
* BreakTheCutie:
** Happens a lot to Eduardo.
** Mac also goes through this.
** Wilt in ''Where There's a Wilt, There's a Way.''
** Frankie whenever she's punished by Mr. Herriman.
* BrickJoke:
** Happens in "Nightmare on Wilson Way". Oscar (The big green friend) decides to go Trick or Treating as Blossom from ''WesternAnimation/ThePowerpuffGirls'', Frankie decides to go Trick or Treating as Blossom as well, which leads to Oscar walking away muttering "I should have gone as Bubbles..." In all later scenes he appears in, he's dressed as Bubbles.
** A RunningGag in "The Big Cheese" has Frankie task Wilt with buying an item. Wilt leaves, then comes back later with the item she originally asked for when she needs a different item for the situation. She has him buy light bulbs, a net, a book of nursery rhymes, and a box of candy.
* BrokenTreasure: Madame Foster's bust. [[spoiler: Turns out it happens so often, Mr. Herriman has a closet full of replacements.]]
* BritishStuffiness: The [[UsefulNotes/BritishAccents British-accented]] Mr. Herriman. He's very prim and proper, is strict, and has a very high regard for rules. He also wears a WaistcoatOfStyle, HighClassGlass, and a [[NiceHat top hat]].
* BucketBoobyTrap: Bloo falls victim to the prank of opening a door and having a bucket of water fall on him in "Pranks for Nothing".
* BullyingADragon: In ''Destination Imagination'', Mr. Herriman scolds World and threatens to take Bloo and the gang back to the real world, leaving him utterly alone again. [[OneWingedAngel World does not take this well]]
* BurpingContest: Between Bloo and Blake Superior in "Hiccy Burp", although Bloo is hiccupping instead.
* BuyOrGetLost: In "Race for Your Life Mac & Bloo", at one point Bloo had a PottyEmergency and had to wait in a long line for a store's bathroom key only for the cashier to tell him that he has to buy something first. The funny thing is Bloo actually ''did'' buy something only minutes ago, but since he left the store and came back the "transaction was complete", even though he only set foot outside for a split second.
* TheCameo:
** [[WesternAnimation/ThePowerpuffGirls Mojo Jojo]] [[note]]Or rather an imaginary friend clone, created by a kid who just copied what he or she saw on television[[/note]] appears in the pilot movie.
** Frankie's shirt has silhouettes of Blossom, Bubbles, and Buttercup.
** In one episode, Mandy of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' shows up to return an imaginary friend for being too happy.
** Also, [[WesternAnimation/DextersLaboratory Dexter]] and WesternAnimation/EdEddNEddy make appearances in "Eddie Monster"
* CanadaEh: John Larry [=McGee=], Goofball John [=McGee=]'s creator, is a walking Canadian stereotype.
* CantGetInTroubleForNuthin: Bloo tries to get himself in trouble so he could be sent to bed without supper, so he can avoid eating "it". Unfortunately, Mr. Herriman is also trying to hide his secret stash of carrots, and
%%* CardboardPal
%%* CarFu
%%* CatchPhrase: Parodied.
* CelebrityIsOverrated: "The Sweet Stench of Success" has Bloo become the mascot for a brand of deodorant and realizing that show business isn't all it's cracked up to be.
* CharacterDevelopment: Subconsciously {{Invoked}} by children creating imaginary friends. While many friends are designed by a child to be what they want for fun or personal gain, every friend seems to have an aspect of their character that forces their original child to mature.
** WordOfGod states that Mac would actually be much more of a {{Jerkass}} just like Bloo, but seeing Bloo be punished for such bad behavior keeps him from making the same bad choices in life.
** ''WesternAnimation/GoodWiltHunting'' gives two examples for this straight from the imaginary friend's creators.
*** Nina created Eduardo to scare off a group of bullies while also being loving and gentle with her and her baby brother. This made Eduardo into a PaperTiger. Once the bullies found out, they were merciless to the sensitive Eduardo. This forced Nina to find her own courage to chase the bullies off and protect her creation. She grew up and became a police officer thanks to that day.
*** Wilt's creator made Wilt to teach him how to become a pro at basketball. [[spoiler:In a match against the brutish Foul Larry, Wilt saved his kid's life at the cost of his arm and eye. The boy at first only cared that they lost the match, but after learning about what Wilt sacrificed for him, he realized the error of his ways. Jordan Michaels did become a successful basketball player, but Wilt helped him to become a better, more compassionate person.]]
* ChewOutFakeOut:
** In "Partying is Such Sweet Soiree", Mr. Herriman is warned by Madame Foster not to allow wild parties while she is gone. After Bloo throws a party in spite of Madame Foster's orders to try and get Herriman in trouble, Madame Foster looks like she'll tear into Herriman, but she quickly specifies that the rule was that no wild parties could be thrown without her being there to participate.
** This kind of gag happens again in "Bloo Tube", where Bloo is forced to let Mac, Wilt, Coco, and Eduardo use a laptop to upload a viral video they made with Frankie's camera, which they used without her permission. Bloo tries to get even by telling Frankie that they are using her camera without her permission, but right when it looks like she'll get mad, she instead commends Mac and the others for deciding to make a viral video and encourages everyone else in the house to make their own viral videos.
** This occurs for a third time in "Bad Dare Day" where Mac is caught stealing Madame Foster's gold-plated dentures (which Bloo dared him to do.) Madame Foster stands at the top of the stairs with everyone watching and it seems like she's going to punish anyone who had taken part in a dare, only to start up a daring competition.
* ClingyChild: Parodied in the first episode where Terrence, Mac's older brother, clings to his mother's leg out of defense when she comes home, claiming Mac was bullying him, though [[PlayingTheVictimCard it is obviously the other way around]].
* ClingyJealousGirl: Berry takes this UpToEleven by being psychotically obsessed with eliminating anyone or anything she perceives as interfering with her chances at getting together with Bloo.
* {{Cloning| Blues}} [[IncrediblyLamePun Bloos]]: In "Bloo's Brothers", where several of Mac's classmates are inspired by Bloo to create their own versions of Bloo who all have something wrong with them.
* CheatedAngle: Frankie's hair and Mr. Herriman's monocle are always in the same direction no matter which side they're facing.
* ChuckCunninghamSyndrome:
** Bendy disappeared after his debut episode and was never mentioned again. This was mostly due to the fans' burning hatred of the character and considers the episode the most unfair abomination they've ever seen on the show. [[CreatorBacklash Even the episode's writer, Lauren Faust, apologized for it.]]
** This also applies to any of the one-off episode characters that appear. Lil' Lincoln and Moose never make another appearance after ''Emancipation Complication''. Neither does Red after ''Seeing Red'' nor Omnizot and the Space Nut Boogies after ''Make Believe It or Not''. None of whom were mentioned ever again afterwards either.
* {{Cloneopoly}}: In the episode "Bloo Tube", the gang plays "Farat Trap of Life", which is played on four boards similar to Monopoly, The Game Of Life, Mousetrap, and Pop-O-Matic Trouble.
* {{Cloudcuckoolander}}: All the imaginary friends are like this to some extent, but Bloo (with his insane theories) Coco (with her occasional inexplicable behavior), Cheese (who says random things), and Eduardo deserve special mention.
* CluelessAesop: "Bye Bye Nerdy" is ''dreadful'' to watch for this reason. Bloo freaks out that his creator is a nerd. Mac takes the correct stance - he doesn't care whether he's cool or not. Cue "Jamez Withazee", the self-designated coolest kid who thinks this makes Mac cool. What happens for the majority of the episode is the self-deprecation of Mac, who now only cares what "Jamez" thinks, and must idle around doing nothing. However, neither character nor viewer realize until the episode's end that "Jamez" [[JerkWithAHeartOfJerk horrible world-view of thinking]] that not caring is cool, extends to [[LackOfEmpathy other people's health and well-being as well]]. Mac comes to his senses, and goes to help Bloo, but not before being mocked by "Jamez" and everyone else for being uncool. "Jamez" and his admirers are never called out, or punished, for this.

* ColonCancer: Parodied on ''One False Movie'', with Bloo's movie being called "Trexatron Alienwolf III: A Prequel In Time: The Unrelenting".
* ComicBookAdaptation: Several comic stories based on this show were featured in ''Cartoon Network Block Party''.
* CompanyCrossReferences: Many references to fellow Creator/CartoonNetwork series ''WesternAnimation/ThePowerpuffGirls'', given that both shows are created by Craig [=McCracken=].
** Frankie wears a t-shirt with color-coded silhouettes of Blossom, Bubbles and Buttercup.
** In the pilot movie, Mojo Jojo appears as an "unimaginary" imaginary friend, which are friends based on things kids see on TV.
** In "Cookie Dough", Bloo names off some cities that want shipments of Madame Foster's cookies, including Townsville and ''WesternAnimation/JohnnyBravo'''s Aron City.
** In "Nightmare on Wilson Way", Frankie dresses as Blossom for Halloween.
* ContinuityNod:
** "Bloo Tube" shows that the viral video from "World Wide Wabbit" is still wildly popular.
** In "Bad Dare Day" a "I *heart* FB (Funny Bunny)" cap can be seen in Madame Foster's room
** When Bloo and Madame Foster realize that they've lost some movie tickets right as they arrive at the premiere, he compares it to "that stupid trip to Europe that we never took".
** Some episodes still show the Extremosaur cage.
** In the last episode, while trying to think up things to do with Mac, Bloo rattles off several suggestions that are things the two did in previous episodes throughout the series. Mac even lampshades it.
** In ''Destination Imagination'', Mac foils the sleeping powder attempt with a pretty {{Badass Boast}}: "You don't know this about me: I. Can't. Eat. Sugar."
* ControlFreak: Mr. Herriman, complete with long lists of obscure rules and regulations on such items as placement of toilet paper and how to properly wipe up spills.
* CoolCar: Madame Foster's car resembles a 1970's [[http://en.wikipedia.org/wiki/Pontiac_Firebird Pontiac Trans Am Firebird]], complete with a bird painted on the hood ''a la Film/SmokeyAndTheBandit''.
* CoolOldLady: Madame Foster, especially evident on the bowling episode.
* CrapSaccharineWorld: If you think about it. Because 8 years is considered too old to have an ImaginaryFriend, several live on the street (we have seen this in ''Good Wilt Hunting'') and that is the reason shelters like the one the series focuses on, exist. The Imaginary Friends ''do'' have rights, but not the same as humans do, obviously. For example, they can have jobs and have passports, but killing them is seemingly without repercussions. Plus, there seems to be a difference in Friends depending on age: babies imagine mostly abstract Friends, kids imagine normal Friends, and the ones imagined by older children are so dangerous they have to be locked up.
* CreatorCameo: Craig [=McCracken=] makes an appearance in the episode "One False Movie"
%%* CurseOfTheAncients
*
* CustomBuiltHost: The TV movie ''WesternAnimation/DestinationImagination'' introduces an imaginary friend named World, who is a floating face and mouth that possesses and brings to life whatever he rests on. At the end, Frankie sews together a stuffed patchwork body for him to call his own.
* DarkHorseVictory: In "Hiccy Burp", Bloo and Mac compete at an imaginary friends pageant in hopes of beating an arrogant rival named Richie and his ParodySue imaginary friend Blake Superior. Neither of them win, the victor instead being Armpit Joe.
* DeadlyPrank: Subverted in "Nightmare on Wilson Way". Mr. Herriman appears to die of a heart attack from Bloo surprising him with a can of spring-loaded fake snakes and ends up coming back as a zombie, [[spoiler:but it turns out in the end that Herriman wasn't dead and that the zombie invasion was all an elaborate prank to get back at Bloo]].
* DemotedToExtra: This hapens to Goo and Terrence in later seasons.
* DependingOnTheWriter: ''Lots.'' How much of a jerkass is Bloo - is he a JerkWithAHeartOfJerk or is there a [[JerkWithAHeartOfGold heart of gold in there somewhere]]? How mature is Mac - is he an always do-gooding OnlySaneMan or is he a wise and sensible but still generally childlike and rambunctious kid (sometimes this will change mid episode, with Mac doing something childish and then turning sensible to stop it from going too far)? How mature is Frankie - is she a laid-back CoolBigSis who's always getting dumped on from Mr. Herriman or is she not only very responsible but the only sane adult in the house? Etc, etc - all the different sides of the characters that can be shown at any given time make for a lot of interesting ways plots tend to go.
* DevilInPlainSight: Bendy from "Everyone Knows It's Bendy" is quite obviously a sketchy-looking person and yet Mr. Herriman and Frankie are completely fooled every time he frames Bloo, Wilt, Coco, and Eduardo for one of his misdeeds.
* DiabolusExMachina: An occasional way to end episodes on a gag, used so often that in one episode where he's stuck waiting for Madame Foster to finish shopping Bloo intentionally makes sure to remember a tiny, totally forgotten detail important to the plot (the reason they were there, which the Madame quickly forgot in her shopping) [[LampshadeHanging so they won't have to go back and he can avoid a "wah-wah" moment.]]
* DiegeticSoundtrackUsage: The show's theme music often turns up throughout the series, such as in “Mac Daddy”, where Eduardo sings the tune in the shower.
* DisproportionateRetribution: Many times. One notable example is "Imposter's Home" where rather than stop Bloo from mixing dangerous chemicals, Frankie makes a bet with Bloo that it'll turn out badly. Immature, yes, but what she was put through afterwards (including being forced to miss a concert that she'd been dreaming about for months, with the final slap in the face being that everyone BUT HER got to go) would have been overkill even if she were the one playing with chemicals in the first place. Goofball was a complete {{Jerkass}} to Frankie and Mr. Herriman's treatment of her in this episode bordered on abusive.
* TheDissTrack: In "Setting A President", Bloo and Mr Herriman create an attack ad against Frankie which ends in a song that demonizes her for things she didn't do and glorifies Mr Herriman.
* DisappearedDad: Mac and Terrence's dad isn't even mentioned. One could get the impression that their mother is either widowed or divorced.
* TheDitz: Cheese is a complete moron who's always getting into ridiculous trouble.
* DoesThisRemindYouOfAnything:
** The argument between Mac and Bloo about Cheese's existence is very similar to a wife finding out her husband had a child with someone else.
** In the episode "Affairweather Friends", the title is just the beginning; the whole plot regarding Bloo hiding the fact that he's hanging out with another child plays out a lot like someone cheating on their spouse.
%%* DontThinkFeel: Parodied.
%%* DorkHorseCandidate
* DownerEnding:
** At the end of '''Foster's Goes to Europe''', Eurotrish finally returns to her owner in Europe. Naturally, she must sing a song to express her happiness -- only to be interrupted by her owner shouting out the window, "Stop the singing! Why do you think we sent you away in the first place?" Afterward, Eurotrish dejectedly sulks away, singing, "I'm-a going to America..." There's also the ending for Mac and everyone else, where it turns out that they end up ''not going'' because ''MADAME FOSTER STOLE THE TICKETS.'' And everyone blames Mac, who had spent the entire episode trying to get them out the door.
** In "I Only Have Surprise for You", Mac tries to avoid getting ridiculed and embarrassed through another surprise party by Bloo (even when Mac tells him to stop), after suspecting that Bloo and everyone in Foster's is throwing one for him, by sabotaging and destroying a birthday party in a library with his Rambo-like outfit, only to be told by the house residents that it was for a "4-year old imaginary child" named "Artie" "created by Goo" and made "Artie" running away crying. This made everyone mad at Mac and hate him for ruining "Artie's birthday" before they angrily leave Mac saddened and guilty and Mac must make this up to them and "Artie". So with Bloo's assistance, Mac cleaned up and re-did the party and under Bloo's demands, humiliates himself by reluctantly dressing up and acting like a clown in front of everyone to cheer "Artie" up, only to be revealed that "Artie" was Madame Foster in disguise, the party was for Mac, and that the whole house (except Eduardo as he was just told to come in through via an invitation and One-eyed Cy due to his interest in interior design) [[TookaLevelinJerkass took the jerkass level]] as they all tricked and lied to Mac and took advantage of him for no reason as a rule set up by Bloo to make Mac miserable and ridicule himself. So Mac is left to suffer deliberate humiliation at yet another surprise party that doesn't even celebrate his birthday, while the episode ends with Bloo gloated to him that he'll always be one-step ahead of him.
** The end of "Imposter's Home for Um... Make 'Em Up Pals", when Frankie misses the concert and Goofball turned out to actually be an imaginary friend rather than a teenage slacker lying about being one. Although Frankie apologizes and Goofball thanks her for taking care of him, the ending was still mean-spirited towards Frankie.
** The episode "Everybody Knows Its Bendy", when Bloo gets in trouble yet again after his elaborate scheme of exposing Bendy for his misbehavior and Bendy [[KarmaHoudini gets off completely scot-free for all the misdeeds he framed Bloo, Coco, Wilt, and Eduardo for]].
* DramaticallyMissingThePoint: Tired of getting only one present for christmas every year, Bloo [[YetAnotherChristmasCarol tries to scare Herriman with a very poor reenactment of ''A Christmas Carol'']], (even forgetting to do the Ghost of Christmas Past), and as the Ghost of Christmas Future, tells Herriman not to buy everyone just one Christmas present a year. Unfortunately, Herriman misinterprets this as don't buy ''one single'' Christmas present at all, and proceeds to throw out every Christmas related thing from the house.
* TheDreadedToiletDuty: Frankie hates scrubbing toilets, as shown in two episodes:
** In "The Trouble With Scribbles", Bloo opens the door to the room that houses the Scribbles, the first imaginary friends created by babies. When Bloo gets the Scribbles to do chores for him, Frankie finds out and likes this idea, making one of them scrub the toilets. When humans decide to adopt the Scribbles at the end of the episode, having found out how useful they are, only one Scribble remains. Frankie hopes that it's the toilet-scrubbing Scribble, but to both her dismay and Bloo's delight, it's the Scribble that blows raspberries.
** In "Setting a President", Frankie becomes the new President of Foster's when she wins [[ElectionDayEpisode the election against Mr. Herriman]]. As part of her position as President, she makes a fair chore list, which includes having Bloo scrub the toilets, a job they both deplore.
* DreamDeception: In "Infernal Slumber", Mac's friends unexpectedly show up to his apartment for a sleepover. When a half-asleep Terrence walks into the living room, they get the idea to start acting all wonky to convince him it's all a dream, while Bloo walks him back to his bed. Unfortunately, this allows Bloo to hit him with the shaving-cream-in-the-face prank he's been aching to pull throughout the episode.
-->'''Terrence:''' HEY, WAIT A MINUTE--! ''(SPLAT!)''
* DropInCharacter:
** A rare protagonist DropInCharacter, Mac has to visit the home every day in order to keep Bloo from being adopted.
** Cheese and Goo are also {{Drop In Character}}s of the more standard kind.

!!This show provides examples of:

* TwoDVisualsThreeDEffects: Spoofed in "One False Movie" with the CG Eduardo in Bloo's movie.

** This occurs for a third time in "Bad Dare Day" where Mac is caught stealing Madame Foster's gold-plated dentures (which Bloo dared him to do.) Madame Foster stands at the top of the stairs with everyone watching and it seems like she's going to punish anyone who had taken part in a dare, only to start up a daring comepetition.

* BeCarefulWhatYouWishFor: In the ChristmasEpisode "A Lost Claus", Bloo is dissatisfied with Foster's custom of giving out only one present to each resident every Christmas. He tries to stage a (poorly done) "Christmas Carol" scenario for Mr. Herriman in order to scare him into giving more presents for Christmas. Unfortunately, Bloo (whilst disguised as a [[MakesSenseInContext robot]]) words it in such a way that indicates little foresight on Bloo's part: "There shall be [[ExactWords not one]] present." A couple scenes later, Bloo is sheepishly calling Mac over how his wish has come true: he doesn't have to worry about only getting one present tomorrow, because Herriman ''threw out all things Christmas'' in order to take the advice to heart! So Bloo (along with every resident at Foster's) won't even get the one present.

* LostAesop: "Bye Bye Nerdy" is ''dreadful'' to watch for this reason. Bloo freaks out that his creator is a nerd. Mac takes the correct stance - he doesn't care whether he's cool or not. Cue "Jamez Withazee", the self-designated coolest kid who thinks this makes Mac cool. What happens for the majority of the episode is the self-deprecation of Mac, who now only cares what "Jamez" thinks, and must idle around doing nothing. However, neither character nor viewer realize until the episode's end that "Jamez" [[JerkWithAHeartOfJerk horrible world-view of thinking]] that not caring is cool, extends to [[LackOfEmpathy other people's health and well-being as well]]. Mac comes to his senses, and goes to help Bloo, but not before being mocked by "Jamez" and everyone else for being uncool. "Jamez" and his admirers are never called out, or punished, for this.
