I love that idea of Oswald being the lord of a realm of forgotten rides and cartoons. I'm especially looking forward to seeing what "forgotten rides" end up in the game.
Man... Figment needs to be in it...
He can be the guy that joined Oswald's crew and then was invited back into the main fold later... but it never felt quite the same for him so he swings between allegiances throughout the game!
The Carousel of Progress should also been one of those (incredibly under-appreciated) "forgotten" Disney rides they use in the game for similar reasons.
The talking purple dragon Figment, Maxi, comes from the Journey Into Imagination ride at EPCOT in Disney World. His ride was replaced by an incredibly
bad ride called "Journey Into
Your Imagination" after several years. People complained about him being gone so he was put back into the existing ride, which still sucks. He's basically just "there" and serves no other purpose.
As for other pre-Mickey Disney characters, they mostly just consist of throw-away generic characters from the Alice shorts and Disney's really early cartoon work. Nothing anyone would really recognize outside of Oswald.
