''Mickey Mousecapade'', or ''Mickey Mouse: Adventures in Wonderland'' as it was originally titled in Japan, is the earliest known Creator/{{Disney}}-based video game to be released on the UsefulNotes/NintendoEntertainmentSystem, and one of the few not developed by Creator/{{Capcom}} (although they did publish its American release, it was developed by Creator/HudsonSoft). The game follows [[WesternAnimation/MickeyMouse Mickey]] and WesternAnimation/MinnieMouse as they venture through Wonderland to find their mystery friend, who is being held captive by the evil [[strike:Queen of Hearts]] Maleficent. Along the way, though, a lot of the creatures they encounter have decided for no apparent reason that the mice need to be exterminated, so Mickey and Minnie have to fight these creatures off as they look for their friend.

In gameplay terms, the game is a fairly standard side-scrolling platformer, with Mickey and Minnie navigating jumping puzzles, collecting keys to unlock doors and shooting nondescript "stars" at enemies. This might have been a surprise to any parents who were hoping for something less violence-intensive than, say, ''SuperMarioBros'' Minnie lagged slightly behind Mickey, much like the second Ice Climber in ''[[VideoGame/SuperSmashBros Super Smash Bros. Melee]]'', and could occasionally be kidnapped by a random bird, forcing Mickey to get her back.

A ROM hack that replaces the characters with the cast of ''WesternAnimation/PhineasAndFerb'' was released in 2016. In that version, Doofenshmirtz had kidnapped Candace. Phineas, Ferb, Isabella, Buford, Perry and Pinky team up to save Candace.

* BigBad: Maleficent in the US version, Queen of Hearts in the Japanese version.
* ClimaxBoss: Pete (US version) and Captain Hook (Japanese version), being the fourth out of five bosses and appearing in the shortest level in the game. The former even appears on the US box art.
* CoOpMultiplayer: Predating ''VideoGame/SonicTheHedgehog2'' by a few years, plugging a controller into player 2 will allow another player to play Minnie, selective invulnerability and all.
* CulturalTranslation: Capcom changed most of the items and enemies in the American version.
* BearsAreBadNews: The bear enemies in the Woods level (the Fall and Winter sections), in the American release only. They take away a large chunk of your health bar and can easily and instantly kill you if your health is low enough.
* DolledUpInstallment: A variation: The game itself was already a Mickey game, but many changes were made for the localization, most notably in the enemies. Both versions make use of Disney villains for bosses but not one of them is present in both versions. For example, the Cheshire Cat from ''Disney/AliceInWonderland'' is the first boss in the Japanese version, but in the US version he was replaced by [[AdaptationalVillainy Witch Hazel]]. Many Disney characters who appear as regular foes in the Japanese version were also replaced in the U.S. version by other Disney baddies. The Japanese version was based, first and foremost, on ''Alice in Wonderland'' and most references about Disney on this version derive from the same movie, although some references to ''Disney/PeterPan'' are also made, such as having Captain Hook as the fourth boss in the game, in which the level is themed to a pirate ship. The U.S. localization used a more varied formula, with enemies coming from such Disney films as ''Disney/TheJungleBook'' (the boss of the third level is Kaa) and ''Disney/SleepingBeauty'' (the final boss is Maleficent). Also, in the U.S., the boss of the pirate ship level is a pirate version of {{WesternAnimation/Pete}}.
* FourSeasonsLevel: The maze-like Woods level has seasonal variations, where walking through a doorway in a tree would change from spring to summer, fall, and winter, or backwards.
* GameplayAllyImmortality: Minnie can't get hurt by the normal enemies or the bosses' projectiles, so if you gather her stars at the beginning, she becomes a GameBreaker against [[strike:the Cheshire Cat]] Witch Hazel and [[strike:Captain Hook]] Pete. This said, if she falls down a pitfall and Mickey doesn't, it's still a loss of a life.
* GangplankGalleon: The fourth level, themed to a pirate ship.
* GuideDangIt: The Winter section of the Woods. The hidden door to the final section is in the tree right at the start, but won't open until you go all the way through and loop back to the start, so many players would think there is no door there at all and eventually admit defeat and consult the helpline after shooting every other tree to no avail.

* OneHitKill: All the bosses do this to you.
* RespawningEnemies: This gets especially cruel on levels where you have to backtrack. Even the instant-death-on-contact minibosses respawned, which meant that you could get stuck in an {{Unwinnable}} situation if you missed the key in the castle.
