I haven't noticed Wario move frame-by-frame, and if he does, that's really stupid.
I'd think this would be one of those special stages like the Mushroom Kingdom or the Underground Maze in SSBM. Y'know, it's more linear: Play a bunch of microgames, then a boss one, and then you win (though I suppose it could loop... there'll be more microgames, no doubt; otherwise that'd get really boring...
