Mickey's Steamroller is the Projector Screen that connects OsTown to the first part of Mickeyjunk Mountain. It is based on the 1934 Mickey Mouse cartoon of the same name.
In the level you can either ride the steamroller or run ahead to try and get items.
- This was the first cartoon to feature Mickey's nephews, Morty and Ferdie Fieldmouse.
- The music for this level is included in the soundtrack as a part of the song "Transition Games 2".
- Later in the game, Oswald reroutes this level so that, instead of taking you to The Piles, it goes directly to his Sanctuary.
