History ContinuityCavalcade / WesternAnimation

* Inverted in ''WesternAnimation/BatmanTheAnimatedSeries''; the Batcave is full of nods to trophies that appear in its counterpart in the comics, and some episodes of this and other DCAU shows (such as the Two-Face segment on "Almost Got Him" and Superman fighting a robotic T-Rex in the pilot to ''WesternAnimation/SupermanTheAnimatedSeries'') retroactively explain how they got there. Played straighter in ''WesternAnimation/BatmanBeyond'', where the Batcave will often display trophies from [=B:TAS=] such as Mr. Freeze' freeze gun or the uniforms of Bats' various sidekicks.

** The "Simpsonsworld" segment from "[[Recap/TheSimpsonsS34E6TreehouseOfHorrorXXXIII Treehouse of Horror XXXIII]]" takes place in a futuristic amusement park based on the show, with so many references [[ContinuityCavalcade/TheSimpsonsS34E6TreehouseOfHorrorXXXIII it has it's own sub-page]].

Examples of ContinuityCavalcade in western animation.

* ''WesternAnimation/{{Futurama}}'':
** The Robot Devil's wheel with the name of every robot ever seen on the show in the episode "[[{{Recap/FuturamaS4E18TheDevilsHandsAreIdlePlaythings}} The Devil's Hands Are Idle Playthings]]".
** During Fry's funeral in "[[{{Recap/FuturamaS4E12TheSting}} The Sting]]", every character who had ever been romantically involved with him during the show appeared in one shot.[[note]]except for Amy who was sitting in the front row along with Fry's other friends, and Umbriel the mermaid from Atlanta[[/note]] Including an inanimate radiator.
** The [[https://theinfosphere.org/File:Audience.png scene]] from "[[{{Recap/FuturamaM4IntoTheWildGreenYonder}} Into the Wild Green Yonder]]"--it was planned to have ''literally every'' previously shown character in it, but to keep continuity with a line in script, it's instead every ''adult'' character.
** In "[[{{Recap/FuturamaS6E7TheLatePhillipJFry}} The Late Phillip J. Fry]]", when Fry, the Professor and Bender jump through to the birth of a new universe, they quickly go through several ''Futurama'' events, including the two destructions of New York seen in "Space Pilot 3000".
* In the actual ''WesternAnimation/HigglytownHeroes'' GrandFinale ''Calling All Heroes!'', all of the previous Higglytown Heroes themselves returned.
* ''WesternAnimation/TheSimpsons'':
** Maude Flanders' funeral in "[[Recap/TheSimpsonsS11E14AloneAgainNaturaDiddily Alone Again, Natura-Diddily]]" opens with a panning shot of the Springfield Cemetery with the gravestones of several characters who died in previous episodes (including Beatrice Simmons, whose name is followed with [[Recap/TheSimpsonsS2E17OldMoney "(GRANDPA'S GIRLFRIEND)"]]).
** In ''WesternAnimation/TheSimpsonsMovie'' there's a shot of the townsfolk coming after the Simpsons with torches, which includes every character that has ever appeared on the show. This also applies for all crowd shots in the movie. In the show, nameless, random people fill the crowds with random recurring characters sprinkled here and there. In the movie, as a bit of PanderingToTheBase, there are no nameless, random people in the crowds. They all consist of characters who have appeared on the show at least once.
** "[[Recap/TheSimpsonsS8E23HomersEnemy Homer's Enemy]]" - Frank Grimes marvels at Homer's wall covered with pictures of Homer being in space ("[[Recap/TheSimpsonsS5E15DeepSpaceHomer Deep Space Homer]]"), touring with Music/TheSmashingPumpkins ("[[Recap/TheSimpsonsS7E24Homerpalooza Homerpalooza]]") and having a beer with UsefulNotes/GeraldFord (the ending of "[[Recap/TheSimpsonsS7E13TwoBadNeighbors Two Bad Neighbors]]"). Homer also mentions that he won a Grammy ("[[Recap/TheSimpsonsS5E1HomersBarbershopQuartet Homer's Barbershop Quartet]]").

** "[[Recap/TheSimpsonsS13E22PoppasGotABrandNewBadge Poppa's Got a Brand New Badge]]" - [[LongList Homer lists all the jobs he's ever had up to that point]]. Marge, meanwhile, has a LongSpeechTeaTime.
** Any time the attic or the closet is shown, various items from past episodes are seen stored there. You might see a Pin Pals jacket from "[[Recap/TheSimpsonsS7E12TeamHomer Team Homer]]", or a painting of Music/RingoStarr from "[[Recap/TheSimpsonsS2E18BrushWithGreatness Brush with Greatness]]". The Olmec head from "[[Recap/TheSimpsonsS2E22BloodFeud Blood Feud]]" can be consistently seen in the basement.

** ShowWithinAShow example; in "[[Recap/TheSimpsonsS16E17TheHeartbrokeKid The Heartbroke Kid]]", the episode of ''The Itchy and Scratchy Show'' that Bart watches, "Kitty-Kill Condition" has Scratchy check into a feline cardiologist's clinic. Scratchy fills out a form that asks him if he's ever been churned into butter ("Butter Off Dead"), decapitated by a windmill ("What's Nuked, Pussycat?"), impaled by the Space Needle ("Skinless in Seattle"), squashed by the moon ("Flay Me to the Moon"), printed into money ("The Buck Chops Here"), tricked into eating himself ("Esophagus Now"), hung by his own intestine ("Why Do Fools Fall in Lava?"), impaled on a cactus ("Germs of Endearment"), and killed in a plane crash with Buddy Holly ("Bleeder of the Pack"). Scratchy answers yes to every single one of these.
** In "[[Recap/TheSimpsonsS19E9EternalMoonshineOfTheSimpsonMind Eternal Moonshine of the Simpson Mind]]", in a sequence that pays homage to the Website/YouTube video "Noah takes a photo of himself every day for 6 years", there are scenes that reference episodes that deal with Homer's past in some way (such as "[[Recap/TheSimpsonsS7E8MotherSimpson Mother Simpson]]" and "[[Recap/TheSimpsonsS2E12TheWayWeWas The Way We Was]]"), and towards the end we get a montage of Homer wearing various costumes he had worn throughout the show's history.
** The CouchGag at the beginning of the [[Recap/TheSimpsonsS23E14AtLongLastLeave 500th episode]] was a rapid-fire montage of ''every other CouchGag in the history of the series.''
** The "Simpsonsworld" segment from "[[Recap/TheSimpsonsS34E6TreehouseOfHorrorXXXIII Treehouse of Horror XXXIII]]" takes place in a futuristic amusement park based on the show, with so many references [[ContinuityCavalcade/TheSimpsonsS34E6TreehouseOfHorrorXXXIII it has it's own sub-page]].

** In "[[Recap/TheSimpsonsS13E16WeekendAtBurnsies Weekend At Burnsie's]]", when Marge assembles the scarecrow, a small bubble of [[MetaGuy Comic Book Guy]] appears and relates the episodes the items used are from. For those curious, said items include Lisa's jersey from "[[Recap/TheSimpsonsS6E8LisaOnIce Lisa on Ice]]", Bart's jockey pants from "[[Recap/TheSimpsonsS11E13SaddlesoreGalactica Saddlesore Galactica]]", a Jack-O-Lantern from multiple WesternAnimation/TreehouseOfHorror episodes (specifically [[Recap/TheSimpsonsS4E5TreehouseOfHorrorIII III]], [[Recap/TheSimpsonsS10E4TreehouseOfHorrorIX IX]], and [[Recap/TheSimpsonsS13E1TreehouseOfHorrorXII XII]]), and a hole-bearing fedora from [[UnInstallment the fictitious]] [[NoodleIncident "Who Shot Grampa's Hat?"]] (the hat itself actually comes from "[[Recap/TheSimpsonsS8E5BartAfterDark Bart After Dark]]").
** [[MilestoneCelebration As the tenth]] "[[WesternAnimation/TreehouseOfHorror Treehouse Of Horror]]" episode, the CouchGag for "[[Recap/TheSimpsonsS11E4TreehouseOfHorrorX Treehouse Of Horror X]]" shows the Simpsons (except Lisa, who's wearing a simple axe-in-head costume) as various [=TOH=] characters: Homer as the jack-in-the-box in "[[Recap/TheSimpsonsS3E7TreehouseOfHorrorII Treehouse of Horror II]]"'s "Bart's Nightmare", Marge as her witch self in "[[Recap/TheSimpsonsS9E4TreehouseOfHorrorVIII Treehouse Of Horror VIII]]"'s "Easy Bake Coven" (albiet with her normal yellow skin rather than green skin like in the segment), Bart as the fly-headed hybrid from "Treehouse of Horror VIII"'s "Fly vs. Fly", and Maggie as Kang's mutant child in "[[Recap/TheSimpsonsS10E4TreehouseOfHorrorIX Treehouse Of Horror IX]]"'s "Starship Poopers".

* ''WesternAnimation/TheLegendOfKorra'':
** "Beginnings" references almost every single thing known about the lore from the previous series surrounding the nature of the Avatar, and it also references important scenes from the series finale of ''The Last Airbender''.
** In "The Stakeout", Zaheer references Korra's separate encounters with President Raiko and the Earth Queen, the Air Nomad genocide done by the Fire Nation, the characters of [[spoiler: Wan and Vaatu,]] the spirit portals, and Unalaq all in one sitting.
** "Venom of the Red Lotus" has crystal caves similar to the ones found in the Book 2 finale of ''The Last Airbender'', a battle setting reminiscent of the final battle also in the original series, the [[spoiler: villains of the previous seasons making cameos,]] and there is an important CallBack to a central weakness of the Avatar State.
* ''WesternAnimation/FostersHomeForImaginaryFriends''
** In "[[Recap/FostersHomeForImaginaryFriendsS3E12SettingAPresident Setting a President]]", Bloo nominates himself as a candidate for the President of Foster's in the election against Frankie and Mr. Herriman. When Mac interviews Bloo, he reminds Bloo of all the bad things he did in the past, such as destroying Madame Foster's bust ("[[Recap/FostersHomeForImaginaryFriendsS1E2Busted Busted]]"), opening the secret door that houses the Scribbles ("[[Recap/FostersHomeForImaginaryFriendsS1E7TheTroubleWithScribbles The Trouble With Scribbles]]"), uploading an embarrassing video of Mr. Herriman to the internet ("[[Recap/FostersHomeForImaginaryFriendsS1E9WorldWideWabbit World Wide Wabbit]]"), sabotaging Frankie's date ("[[Recap/FostersHomeForImaginaryFriendsS2E6FrankieMyDear Frankie My Dear]]"), throwing a wild party against Madame Foster's wishes ("[[Recap/FostersHomeForImaginaryFriendsS2E1PartyingIsSuchSweetSoiree Partying is Such Sweet Soiree]]"), flooding the house ("[[Recap/FostersHomeForImaginaryFriendsS2E2AWiltWayEveryoneKnowsBendy Everyone Knows It's Bendy]]"), blowing the roof off the house ("[[Recap/FosterHomeForImaginaryFriendsS2E5CookieDough Cookie Dough]]"), destroying a beloved elephant squeak toy ("[[Recap/FostersHomeForImaginaryFriendsS2E8Squeakerboxxx Squeakerboxxx]]"), and ruining his reputation at school ("[[Recap/FostersHomeForImaginaryFriendsS2E11ByeByeNerdy Bye Bye Nerdy]]").
** The series finale, "Goodbye to Bloo" has several of these:
*** Throughout the episode, the background is full of occasionally-seen objects like the secret door the Scribbles used to be in, the door to the room the imaginary fleas stay in, and the Extremosaur pen.
*** Bloo tries to find something great to do with Mac, but all the things he lists are things they'd done already.
*** The episode ends with goodbye card for Mac, which is signed by every imaginary friend to have appeared on the show (and [[CreatorCameo Craig McCracken]]). The inside of the card is only visible for a few seconds, so it's something of a FreezeFrameBonus.
* ''WesternAnimation/SouthPark'':
** The 200th episode, "[[Recap/SouthParkS14E5TwoHundred 200]]", which not only features a plot that was just a pastiche of a few previous episodes to feature the biggest continuity gag '''ever''', it also features 200 celebrities the people of South Park have parodied (including some who had not previously been shown like Creator/TimBurton), with an ''epic'' redux of [[spoiler:[[Recap/SouthParkS1E12MechaStreisand Mecha-Streisand.]]]]
** The following episode, "[[Recap/SouthParkS14E6TwoHundredOne 201]]", does it again, continuing the story while connecting it to just as many previous episodes' plots, culminating in [[spoiler:Scott Tenorman from "Scott Tenorman Must Die" as TheManBehindTheMan led by his army of ginger-haired people from "Ginger Kids".]]
* ''WesternAnimation/CodenameKidsNextDoor''

* ''WesternAnimation/PhineasAndFerb'''s "Rollercoaster: The Musical" episode in its entirety, especially the last song, [[https://www.youtube.com/watch?v=MyEIEJOYo2Q "Carpe Diem".]]
** Likewise, "Curtain Call/Time Spent Together" from "[[GrandFinale Last Day of Summer]]" is a musical highlight reel of some of the show's most memorable events.
** Near the end of ''WesternAnimation/PhineasAndFerbTheMovieAcrossThe2ndDimension'', almost all of the inventions made by the boys throughout the show up to that point are used to fight off Doof-2's army.
* ''WesternAnimation/ThePenguinsOfMadagascar'': Several episodes were concluded with the MonsterOfTheWeek being sent to Hoboken, so when the penguins end up there in "The Hoboken Surprise", they run into all their previous enemies ([[MyFriendsAndZoidberg and Lulu,]] who was shipped there for different reasons).
--> '''Skipper:''' What in the name of returning guest characters? It's villain-mageddon!
* The ''WesternAnimation/CourageTheCowardlyDog'' episode "Ball of Revenge" had [[{{Jerkass}} Eustace]] bring several villains from previous episodes (Katz, Le Quack, the Weremole, the Cajun Fox, the Clutching Foot, and the Queen of the Black Puddle) together to gain revenge on Courage.

* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** The episode "[[Recap/MyLittlePonyFriendshipIsMagicS3E9AppleFamilyReunion Apple Family Reunion]]", as you might guess from the title, has an appearance from nearly ''every single Apple Family member'' from the first three seasons. There are even a few ponies at the reunion that weren't previously connected with the Apple family, such as recurring background ponies Cherry Berry, Golden Harvest, and Cloudchaser, as well as Hayseed Turnip Truck from "[[Recap/MyLittlePonyFriendshipIsMagicS2E9SweetAndElite Sweet and Elite]]".
** The episode "[[Recap/MyLittlePonyFriendshipIsMagicS3E13MagicalMysteryCure Magical Mystery Cure]]" features Princess Celestia showing Twilight how far she's come with floating clips from just about every previous episode. Also, when the members of the Mane Six are [[spoiler:changed back to their true destinies,]] clips of them doing their jobs fly in rapid succession through their eyes.

** "[[Recap/MyLittlePonyFriendshipIsMagicS5E13DoPrincessesDreamOfMagicSheep Do Princesses Dream of Magic Sheep?]]" is an onslaught of callbacks to gags and plot points from previous episodes during the final dream sequence, from major ones like Flutterbat and the Power Ponies to incredibly minor ones like Beefcake Spike from his imagine spot from "[[Recap/MyLittlePonyFriendshipIsMagicS1E19ADogAndPonyShow A Dog and Pony Show]]" and even the classy lamp brought to life by Discord's sneeze in "[[Recap/MyLittlePonyFriendshipIsMagicS4E11ThreesACrowd Three's A Crowd]]".

* In the ''WesternAnimation/{{Archer}}'' Season 5 premiere "White Elephant", after the characters in the main cast are all arrested for treason by the FBI, all of them--with the exception of Lana and Archer--immediately start blabbing to their interrogators in hopes of escaping prison time. Cue a long montage of everyone recounting past missions from about twenty previous episodes, to a gaggle of increasingly perplexed FBI agents.
* Inverted in ''WesternAnimation/BatmanTheAnimatedSeries''; the Batcave is full of nods to trophies that appear in its counterpart in the comics, and some episodes of this and other DCAU shows (such as the Two-Face segment on "Almost Got Him" and Superman fighting a robotic T-Rex in the pilot to ''WesternAnimation/SupermanTheAnimatedSeries'') retroactively explain how they got there. Played straighter in ''WesternAnimation/BatmanBeyond'', where the Batcave will often display trophies from [=B:TAS=] such as Mr. Freeze' freeze gun or the uniforms of Bats' various sidekicks.
* ''WesternAnimation/ScoobyDooMysteryIncorporated'' does this in the Season 2 episode "Wrath of the Krampus", where [[TheReveal the ending]] reveals that the entire episode's MonsterOfTheWeek plot was actually a scam that the gang pulled off with the help of several of their previous adversaries to steal the three pieces of the Planespheric Disc from Mr. E's vault. The Krampus turns out to be Charlie the Robot (from the [[WesternAnimation/ScoobyDooWhereAreYou original series]] episode "Foul Play in Funland") remotely controlled by Jason Wyatt (from "Howl of the Fright-Hound"), who pretends to pursue Mary Anne Gleardan (from "The Song of Mystery") to distract Mr. E and his allies while Marcy "Hot Dog Water" Fleach (a {{recurring character}} who was the MonsterOfTheWeek in "Menace of the Manticore" and "Night on Haunted Mountain") burgles the vault (using the knowledge of Mr. E's headquarters that she obtained while serving as his operative in "House of the Nightmare Witch"), with the now-incarcerated Mayor Jones (not seen since "All Fear the Freak") safe-guarding the gang's Planespheric Disc pieces while they switch them out with a set of fake pieces. For bonus points: Grady and Greta Gator (from "The Creeping Creatures"), Alice May (from "The Legend of Alice May" and "Pawn of Shadows"), Grandma Moonbeam (from "When the Cicada Calls"), Dan Fluunk (from "Night Terrors") and Ernesto (from "The Shrieking Madness" and "The Siren's Song") can all be seen in the prison cafeteria, and the Green Ghosts (from the original series episode "A Night of Fright is No Delight") show up as enemies in an arcade game.
* In ''WesternAnimation/EdEddNEddysBigPictureShow'', at the joke factory, Eddy pranks Ed by offering him a stick of electric gum. When Ed gets shocked, he flashes between several of the forms and outfits that he's had over the course of the series.
** In the episode "The Good Ol' Ed", the Eds decide to create a time capsule and bring multiple objects from past scams and episodes.

* ''WesternAnimation/TheAmazingWorldOfGumball'': The song "Nobody's a Nobody", from "The Compilation", references many past episodes.

The Tillermans skating with Glorious Gary, while Owen still struggles, and they're doing the "Side Slide" from "[[Recap/CentralParkS1E2SkatersCircle Skater's Park]]".
