You know what?
It's weird that Donald duck and/or Ducktales has inspired more ttrpg than Mickey.
Because I'd have 3 nickels.
I know that Europe has a deep love for the duck family, thank you italian comics.
So Europe gave us Feathered Adventures, a game inspired by the latest season of Ducktales, and Dragonbane, a game in which Donald Duck is a playable race (irascible duck persons) (also don't tell me that illustration of a cloaked duck with two blades doesn't remind you of Darkwing Duck)
There is a Mork Borg version of Ducktales that recently joined my shelves (though I already had the pdf from the crowdfunding, like I said Europeans love that duck) called Dukk Borg. Though only 4 classes (5 with the cursed vigilante). That's not enough to satiate my hunger for Ducktales references.
Meanwhile I know of 2 games that are inspired by Disneyland (the happiest apocalypse on earth and You must sneak human remains into Disney world) but I know of none that have an inspiration directly from Mickey. (They are right though, Donald is a superior character to Mickey)
