History WhatHappenedToTheMouse / AnimatedFilms

* In the third ''Animation/PleasantGoatAndBigBigWolf'' movie, ''Animation/MoonCastleTheSpaceAdventure'', [[spoiler:Wolnie's new babies]] are involved in a movie-wide arc about [[spoiler:Wolnie's being pregnant with them; they only physically appear at the end of the film after being born]]. They are referenced exactly once in ''Animation/MissionIncredibleAdventuresOnTheDragonsTrail'', which succeeds ''Moon Castle'', and never actually appear in it or any of the later films.

* In ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'', it's never explained what happened to [[spoiler:Karen after the time machine was destroyed, although it's safe to say that Plankton rebuilt her after the events of the movie]].

* In ''WesternAnimation/MortalKombatLegendsScorpionsRevenge'' Kitana makes a couple appearances in the tournament hall, she later appears to fight Liu Kang but decides that their fight is pointless and leaves, she never shows up again, not even during the final battle.

* At the end of ''{{WesternAnimation/Balto}}'', [[BigBad the evil dog]] [[GloryHound Steele]] is never seen, heard, or mentioned again after Balto safely arrives in Nome with the diphteria medicine, thus exposing all of Steele's crimes in front of everyone, and immediately causing them all to turn against Steele and start branding him as an outcast like with Balto was at the very beginning of the movie. Steele also noticeably doesn't even return in any of the sequels, nor do they ever mention him again afterwards. Although [[WhatCouldHaveBeen there were originally plans during development of the third movie where Steele was actually going to return and]] [[HeelFaceTurn potentially be redeemed at some point.]]

** Monsieur D'Arque doesn't show up for the mob song, and nothing is known about what happened to him afterwards.

* Semi-literal example from ''WesternAnimation/TheMagicVoyage'': Throughout the movie a trio of rats become Pico's unwilling companions aboard Columbus' ship. Near the end they crash onto an island while the rats decide to escape by manning a lifeboat; during the crash they collide with the boat causing it to wash up on an island. When the rats are recovered from the wreckage the leader is nowhere to be seen and remains missing for the rest of the film; it can be assumed that he died in the wreck and his absence goes unmentioned by the rest of the characters.

** The bimbettes. They constantly accompany [[BigBad Gaston]] during the first half of the film, but for some reason are completely absent during the last half of the film where the villagers are raiding the Beast's castle. The musical adaptation has them included among the villagers who go to attack the castle. Presumably they are scared away along with everyone else, in the ensuing fight. We never see [=LeFou=]'s, the bimbettes' or other villagers' reactions to Gaston's death either.

* ''WesternAnimation/ACharlieBrownThanksgiving'' opens with the classic "Lucy & The Football" gag. However, after this opening scene, Lucy is never seen again in the entire special!

* The first half of ''WesternAnimation/TheSimpsonsMovie'' focuses on Homer getting a pig, Plopper. But after the family is driven out of town, he is completely absent for the rest of the movie. He briefly appears in one of the alternate ending sequences on the DVD, but the final cut implies he died when the Simpsons' house was destroyed. He eventually reappears in the CouchGag of the first episode to air after the movie, "He Loves to Fly and He D'ohs", in which he is described by Homer as his "summer love".

* In WesternAnimation/HappilyNeverAfter the two ugly stepsisters accompany their mother Frieda for the first third of the movie, they are last seen at the ball attempting to seduce Prince Humperdink, after Frieda takes over the kingdom using the wizard’s staff they just disappear and are never seen again, being her daughters and all you’d think they would’ve been by her side during her rule.

* Likewise in ''WesternAnimation/{{Pinocchio}}'' no second thought is apparently given to save the boys on Pleasure Island or asking the fairy to restore their humanity. This may be because in the original story Pinocchio doesn't try to help these boys [[spoiler:even after he meets one of the donkeys that used to be a boy after leaving Pleasure Island.]]

** What really happened to the Duloc Tournament Knights when Farquad dies by getting eaten by Dragon near the end?
** The movie mentions that Fionna was cursed by a witch to turn into an ogress. We never find out what happened to this witch or why she cursed Fionna in the first place. However, it is implied that Fairy Godmother was the one who cursed her.

* The first half of ''WesternAnimation/TheSimpsonsMovie'' focuses on Homer getting a pig, Plopper. But halfway through, the pig disappears and never returns in the second half (though he briefly appears in one of the alternate ending sequences on the DVD). He eventually appears in a later television series episode, in which he is described by Homer as his "summer love".

* In ''WesternAnimation/TheSpongebobMovieSpongeOutOfWater'', it's never explained what happened to [[spoiler:Karen after the time machine was destroyed, although it's safe to say that Plankton rebuilt her after the events of the movie]].

** Al first rubs the lamp because he thinks he sees writing on it but can't make it out. He's understandably too distracted by an elaborate song-and-dance number directly afterward to double-check, but was there really writing there, and if so, what does it say?

* ''WesternAnimation/TheIncredibles'':

* ''WesternAnimation/{{Shrek}}'': What really happened to the Duloc Tournament Knights when Farquad dies by getting eaten by Dragon near the end?

** For that matter, it's never mentioned what happens to the Kingdom of Duloc after it's left without a ruler. It does appear in the halloween short WesternAnimation/ScaredShrekless, but no residents are to be seen.

** Earlier on in the film, Bill the Lizard is never seen again for the rest of the film after being blasted out of the White Rabbit's chimney and up into the sky while trying to extract the giant Alice from the Rabbit's house(Ironically, in the novel, he appears in the trial as a member of the jury).

* ''WesternAnimation/TheLittleMermaid'': King Triton's seahorse herald disappears from the movie midway through the second act, with no word on if he found Ariel.

* In the third ''Animation/PleasantGoatAndBigBigWolf'' movie, ''Moon Castle: The Space Adventure'', [[spoiler:Wolnie's new babies]] are involved in a movie-wide arc about [[spoiler:Wolnie's being pregnant with them; they only physically appear at the end of the film after being born]]. They are referenced exactly once in the fourth film and never actually appear in it or any of the later films.

* Throughout all five ''WesternAnimation/DespicableMe'' movies, Bob and Otto(and that minion-chick whatchamacallit) only ever appear in the ''Minions'' duology, and are never seen or spoken of in the ''Despicable Me'' trilogy.

* In ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'', it's never explained what happened to [[spoiler:Karen after the time machine was destroyed, although it's safe to say that Plankton rebuilt her after the events of the movie]].
