OK so after a lot of annoying research to clear out the stages completely...this is the best I've gotten so far. It has a floor, walls, and corners. Most of the stage is stripped; however, the wall blast items remain and the big destructive building in the background. Based on my tests, animation has no direct interaction with the characters and shouldn't have any impact on gameplay.

I'm taking a break to work on other stuff for now so please enjoy and check out the other potato stages in version 2.
