My proposal for the A project is my idea of the One Man's Dream concept about the history of Disney theme parks, mainly Disneyland. I was thinking of putting it in the Main Street Cinema, since they have a screen there anyway.
Also...
For a name, how about Mickey's Magical Adventure? Sorry, it's the best I could do on short notice. Also, instead of Mickey himself dropping the magic bag, maybe there could also be Goofy as his assistant, and he drops the bag. In a way, it would not only be the spiritual successor to Mr. Toad, but also to Mickey's PhilharMagic.
One question: how would chaos be spread in this ride?
