Ok there has to be a Pullblox level in Smash Wii U now
Fighting on the changing platforms as little Mallo is reshaping the level and going about his business. Maybe you can interact with him, maybe not. Maybe you can use the Ladders in the level as well to move from top of the stage to the bottom, but if any point you hit Mallo you get Smashed Out.
The level could rewind at some point, meaning the platforms move really quickly, and then Mallo will start again, this time moving the platforms differently.
