Western Animation: Foster's Home for Imaginary Friends

Foster's Home for Imaginary Friends is an animated television series that aired from August 2004 to May 2009 for a total of 79 episodes in six seasons. The premise is based on a simple question. In a World where imaginary friends are living, tangible beings, what happens to those friends when the kids grow up?

According to Cartoon Network and Craig McCracken, they come to Foster's, 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 a child who needs them. The show follows Mac, a shy and creative 8 year old boy, whose imaginary friend Bloo is thrown out of Mac's home and forced to come live at Foster's. Mac doesn't want Bloo to be adopted by another kid, so it's agreed that Bloo will not be put up for adoption, provided that Mac come and play with him every day. Bloo's egotistical, mischievous nature is the complete opposite of Mac's, and together the two cause all manner of chaos throughout the house.

Everyone can see and hear the friends, not just their creators. Since almost all of the characters are imaginary friends dreamed up by children, the show's cast consists of an array of impossible creatures, sometimes bordering on the surreal. There's strong characterization throughout, however, even as the highly comedic plots tend to rely on Bloo causing ever-escalating mayhem. Is known to have loads of Parental Bonuses as well.

Over the course of the series, two Made For TV Movies have been released: Good Wilt Hunting in 2006, and Destination Imagination in 2008. Both of them are noticably Darker and Edgier than the series itself.

In 2012, the series returned to Cartoon Network as a part of Cartoon Planet, 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 Boomerang. In March 2013, the series was put on Netflix.

This show provides examples of:

  • Absentee Actor: 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).
  • Accent Adaptation: Hispanic imaginary friend Eduardo has a US accent in the Spanish dub.
  • Accidental Misnaming: Bloo constantly forgetting Berry's name in "Berry Scary." He does, however, remember her as "Heather."
    Berry: MY NAME IS BERRY!!!
  • Ad Break Double Take: 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!
  • Adorkable: Mac is the biggest example in the series, but Wilt definitely qualifies during his more "awkward" moments.
  • Affectionate Parody: Eurotrish is a spoof of Tanya Mousekewitz.
    • Morsey is a parody of Morissey, fitting in with the 80s allusions.
  • Alien Geometries: 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!
  • Alliterative Name: Francis 'Frankie' Foster.
  • Anthropomorphic Food: 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.
  • Apologises a Lot: Wilt. "Oh! I'm sorry, is that okay? I'm sorry!"
  • Arbitrary Skepticism: 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.
  • Are You Done Yet: Verbalized by Bloo a few times, while Frankie asks with just an annoyed look.
  • Art Evolution: 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.
  • As Long as It Sounds Foreign: 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.
  • Attention Whore: Bloo, who seems to think It's All About Me, and gets visibly annoyed when the others don't share his excitement in various things.
  • Ax-Crazy: Mac is a very Nice Guy, right? But he's completely lunatic if he gets even the smallest amount of sugar.
  • Baby Talk: Frankie, in "Dinner is Swerved". "I'm sowwy, Mistuh Hewwiman."
  • Bedsheet Ladder: 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.
  • Back Blocking: 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.
  • Big Bad: World in Destination Imagination. He's not actually evil, though, just a scared little kid who's got serious abandonment issues and just wants a friend.
  • Big Bad Duumvirate: Terrence and Duchess in "House of Bloo's", who team up to get rid of Bloo once and for all.
  • Big Brother Bully: Terrence. "Stop! I just want to punch you!"
  • Big Friendly Dog: 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.
  • Bigger on the Inside:
    • 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 Reality Warper.
  • Bilingual Bonus:
    • In the episode One False Movie Coco's subtitles are French for "I do not speak French!".
  • Birthday Episode: There were several such episodes. The birthday celebrated in those episodes were Madame Foster, Mac and Bloo.
  • Bittersweet Ending: The ending to Bloo Tube, when the Monsoon Lagoon-obsessed Bloo has to stay at the home, in bandages and a wheelchair, while the rest of the cast gets to go to the aforementioned water park; the final shot shows the house as we hear Bloo crying hysterically. Sad, yet Bloo spent the entire episode being horrible to everyone else.
  • Bizarrchitecture: The titular Home. It looks odd enough from the outside, but it's full of Alien Geometries and Chaos Architecture 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).
  • Black Comedy: In the last episode, Bloo's first idea to prevent Mac from moving away was to kill him.
  • Book Ends: 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.
  • Break the Cutie:
    • Happens a lot to Eduardo.
    • Mac also goes through this.
    • Wilt in Where There's a Wilt, There's a Way.
  • Brick Joke: Happens in Nightmare on Wilson way. Oscar (The big green friend) decides to go Trick or Treating as Blossom from The Powerpuff Girls, 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.
  • Broken Treasure: Madame Foster's bust. Turns out it happens so often, Mr. Herriman has a closet full of replacements.
  • British Stuffiness: The British-accented Mr. Herriman. He's very prim and proper, is strict, and has a very high regard for rules. He also wears a Waistcoat of Style, High-Class Glass, and a top hat.
  • Colon Cancer: Parodied on One False Movie, with Bloo's movie being called "Trexatron Alienwolf III: A Prequel In Time: The Unrelenting".
  • Continuity Nod: "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."
  • Control Freak: 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.
  • Cool Car: Madame Foster's car resembles a 1970's Pontiac Trans Am Firebird, complete with a bird painted on the hood a la Smokey and the Bandit.
  • Cool Old Lady: Madame Foster, especially evident on the bowling episode.
  • Creator Cameo: Craig McCracken makes an appearance in the episode "One False Movie"
  • Crowning Moment Of Indifference: In "Frankie My Dear" when Prince Charming is trying to woo Frankie and she just goes on eating her pizza.
    • After being freed from the toy box, World has this conversation with Mr. Herriman, who had previously wanted to keep him locked inside:
    World: I'm free, Mr. Herriman!
    Mr. Herriman: Splendid.
    World: And Frankie freed me!
    Mr. Herriman: Yes, I saw that.
  • Darker and Edgier: Destination Imagination. It was even rated TV-PG (usually TV-Y7)
    • The entire series may fall under this when compared to the other comedies on Cartoon Network at the time of its premiere.
    • The reason for the TV-PG rating may be Bloo saying "pissed", although the premise alone would have likely been enough.
  • Depending On The Episode: Lots. How much of a jerkass is Bloo - is he a Jerk with a Heart of Jerk or is there a heart of gold in there somewhere? How mature is Mac - is he an always do-gooding Only Sane Man 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 Cool Big Sis 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.
  • Diabolus Ex Machina: 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) so they won't have to go back and he can avoid a "wah-wah" moment.
  • Disproportionate Retribution: 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 Jerk Ass to Frankie and Mr. Herriman's treatment of her in this episode bordered on abusive.
  • Disappeared Dad: Mac and Terrence's dad.
  • Does This Remind You of Anything?: 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.
  • Downer Ending:
    • 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.
    • The end of "Imposter's Home for Um... Make 'Em Up Pals", when Frankie misses the concert and Goofball turned out to be right about being an imaginary friend. Although Frankie apologizes and Goofball thanks her for taking care of him, the ending was still mean-spirited towards Frankie.
  • Earn Your Happy Ending: Frankie and World in The Movie. 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 Big Bad of The Movie and an emotionally unstable Reality Warper 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.
  • Election Day Episode: 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.
  • Emotionally Tongue Tied: Wilt has trouble saying "No" when someone asks him to do something.
  • Episode Title Card: 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.
  • Expospeak Gag: Mr. Herriman's preferred manner of speaking.
  • Expy:
    • Mac is based on a one-time Powerpuff Girls character, Mike, who had an imaginary friend of his own. Also, his early design had a lot in common with Linus van Pelt, which is particularly telling when you remember that Bloo's design was based off a child's security blanket. And 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".
    • Wilt's creator, Jordan Michaels, is an obvious expy of famous basketball player Michael Jordan.
    • Mr. Herriman is based on the White Rabbit from Alice in Wonderland, being a white rabbit with a waist coat and an obsession with being on time, as well as the eponymous character from Harvey, being imaginary and six feet tall.
    • Frankie is based on McCracken's wife, Lauren Faust.
  • Extranormal Institute: Foster's is a place where human kids adopt imaginary friends.
  • Fantasy Kitchen Sink, as well as Fairytale Motifs: Unicorns, giant monsters, superheroes, whatever the heck Coco is supposed to be, and countless other creatures.
    • Coco's been explained, and it's kind of sad. Her creator was a girl who was trapped on a deserted island for a long time, and created an imaginary friend to keep herself sane. Coco is an amalgam of things that the girl could see around her: the crashed plane (Coco's body), the deflated life raft she tried to get off the island with (Coco's beak), a palm tree (Coco's head), and her own sunburned feet (Coco's...feet).
  • Friendly Tickle Torture: 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.
  • Genki Girl: Goo, complete with Motor Mouth and Hair Decs. And possibly Madame Foster and Coco.
  • Gentle Giant: 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 - unless his friends are in danger. Wilt is a very, very tall fellow with one arm who is polite to the point of neurosis.
  • Getting Crap Past the Radar: When Bloo fails to glue Madame Foster's stone head back together with toothpaste, he quips, "A bust this big needs ample support!" When discussing what to build the replacement out of, Ed suggests saline, as he is crying at the time.
    • In the episode "Affairweather Friends", the title is just the beginning.
    • In the episode "Squeakerboxx", Bloo is inside of the men's room squeaking an elephant. Granted, it's literally an elephant and made of rubber, but still....
    • Whenever you see inside Terrence's room, if you look carefully, you'll always see a box of tissues and a bottle of lotion.
    • In the early episode "Dinner is Swerved":
    Bloo: Oh, sheets!
    Mac: *shocked* BLOO!
    • In "Mac Daddy", Mac and Bloo's argument about Mac possibly creating a new imaginary friend sounds a lot like an argument about romantic infidelity.
    • In "Squeeze the Day" Mac suggests while he and Bloo are home alone, they watch Frankie's videos that are for "grown-ups only." We see them watching a video looking shocked. It turns out to be a dramatic period piece that a kid like Mac would find really boring.
    • Bloo's ninja costume in "Duchess of Wails" is quite phallic.
  • Gosh Dang It to Heck!: Frankie. "Holy. Guac. Amolie."
  • Grand Finale: 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.
  • G-Rated Drug:
    • Sugar to Mac.
    • In "Cookie Dough" Frankie's obsession with Madame Foster's cookies is blatantly akin to a cocaine addiction.
  • Gratuitous Spanish: Eduardo. He often throws in various words and calls Bloo "Azul".
  • Growing Up Sucks: The premise is that nearly all kids grow out of needing their imaginary friends, so Mac will likely end up leaving Bloo. 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...
  • Hair-Raising Hare: 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 Berserk Button pressed as seen in "World Wide Wabbit".
  • Half-Dressed Cartoon Animal: Lampshaded in "Adoptcalypse Now".
  • Hands-Off Parenting: 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.
  • Heterosexual Life-Partners: Mac and Bloo, which is particularly funny in "Mac Daddy", when they discuss Mac's creation of Cheese as if Mac cheated on Bloo.
  • Identical Grandson: Frankie looks exactly like photos of a young Madame Foster, and both wear green hoodies and purple skirts.
  • Imaginary Friend: Well, 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.
  • Incredibly Lame Pun: From the pilot movie: "Let's Bloo (do) this!". The gang even reacts to this.
    • Done several times in "Mac Daddy": Mac and Cheese, Bloo Cheese, and finally "Cheese Louise". Cue Mac's Face Palm.
  • Insane Proprietor: Madame Foster is a little more than eccentric, but she does keep the house running, despite her quirks and the general craziness around her.
  • Instant Web Hit: The "Funny Bunny" video in "World Wide Wabbit".
  • Intergenerational Friendship: 22-year-old Frankie and Mac.
  • Interrupted Cooldown Hug: Happens during Destination Imagination. 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 Unstoppable Rage that literally tears the entire reality of the toy chest apart.
  • Intoxication Ensues / Mushroom Samba: Mac on sugar, to the point of tearing off his clothes and running naked through the town.
  • It's a Small Net After All: 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.
  • Jumping the Shark: invokedReferenced in a Show Within a Show and was literally attempted by Bloo in the Series Finale.
  • Kavorka Man: Bloo for Berry. Her being completely insane might have something to do with it.
  • Limited Wardrobe: The human characters always wear the same clothes, as do the few imaginary friends who actually wear clothes.
  • Little Boy Seeks Big Girl: 8-year-old Mac has a crush on 22-year-old Frankie.
  • Mathematician's Answer: 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.
  • Meat-O-Vision: 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.
  • The Millstone: 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.
  • Miniature Senior Citizens: 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.
  • Mock Millionaire: In one episode, several charities compete for the attention of a character pretending to be a millionaire.
  • Mundane Fantastic: Anything a child imagines can come to life in this world. Despite this, the world is otherwise much the same as ours.
  • Mythology Gag: In "House of Bloo's", Bloo is shown at one point watching a Lassie parody. The boy in the show has the same character design as Mac's prototype appearance.
  • Never My Fault: Bloo refuses to accept it's his own fault Eduardo ran away in that episode.
  • No Name Given: Mac's teacher was never given a name.
  • Noodle Incident: 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.
  • Not Allowed to Grow Up: Mac is eight when the show starts, and does not age for the duration of the show.
  • Not Quite Human: 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 Uncanny Valley territory with this.
  • Not So Different: Mac usually plays The Straight Man 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.
  • Obfuscating Stupidity: In "Emancipation Complication", Madame Foster feigns obliviousness to how evil Lil' Lincoln is so he won't realize her plan to take him down.
  • Offscreen Moment of Awesome: Invoked as a subtle gag in "Neighbor Pains."
    Mr. Herriman: "So, you wish to adopt Time-Travelling Tina. We shall sorely miss the 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 a "Coco", she was given dialogue in the script and told to just read it as "coco". Meaning, somewhat out there are written translations of what it is Coco is really saying!
  • One-Winged Angel: World, an emotional unstable Reality Warper, 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.
  • Only One Name: Most of the imaginary friends have no last name. Neither does Mac.
    • Averted, however, with Blooreguard Q. Kazoo.
  • Only Sane Man: 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.
  • Our Founder: Elwood P. Dowd, of Harvey fame, appropriately enough. The Home itself also has a bust of its founder, Madame Foster, which Bloo promptly... busts.
  • Out of Focus:
    • Most of the human supporting characters — Goo, Terrance and Mac's mom — are largely absent in seasons 5 and 6.
  • Reality Ensues: Happens surprisingly often, even as entire episode premises. For example, when Little Lincoln turned out to be a scam artist in a The Farmer and the Viper 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, Fridge Logic comes in given that he looked for every job BUT an administrator, which he was quite skilled at.
  • Reality Warper: 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.
  • Sealed Evil in a Can: 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.
  • Second Person Attack:
    • 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.
  • Selective Enforcement: Inverted as a Springtime for Hitler in the episode "Crime After Crime". The episode's B-plot has Frankie 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.
  • Shaggy Dog Story: Many, many, many episodes.
  • She Is Not My Girlfriend: Mac, concerning Goo (in the first episode she was in, anyway).
  • Shout-Out: Has its own page.
  • Sibling Rivalry: 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.
  • Spotting the Thread: 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.
  • Squashed Flat: Bloo in "Adoptcalypse Now", when a giant, gorilla-like imaginary friend is launched through the window and lands on him.
  • Squishy Wizard: Mac is highly intelligent for an 8-year old, but one drop of sugar and he goes from being the Only Sane Man to making Goo look perfectly sane.
  • Stealth Pun:
    • Cheese has a few of these: Mac created Cheese. You know, "Mac and Cheese?"note  Making Mac's two creations Bloo Cheese.
      • Cheese actually isn't Mac's creation. He belongs to Mac's neighbour, Louise. Like "Cheese Louise".
    • When Bloo tries to get Cheese adopted, he offers a package deal with a Ridiculously Cute Critter named... Crackers.
    • Bloo and Berry. As Berry has a crush on Bloo, this is not accidental.
  • Strange Minds Think Alike: 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.
    • 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?"
  • Straw Feminist: Subverted with Nemesister, who doesn't really have a political agenda. She just likes to destroy or sabotage anything that guys like.
  • The Eighties: The series takes place in the mid 2000s but one episode revolves around Mac trying to be cool. At one point he stars acting like a stereotypical 80s bad boy.
  • Tickle Torture: In the episode "Make Believe it or Not", Bloo and Mac are subjected to this via a Robotic Torture Device called the "Insanolizer".
