Another idea. Kula World X Tekken
During the match you get teleported to a Tekken ball match. xD (Paul Vs. Mokujin)
I like that and the Map hazard as the kula world ball, get hit by it would make you lose AP.
The ball should also be the one from the box art that says Kula World on its side. Oh and for the stage itself, I figured that the Kula World part could be in the psychedelic bonus room. That would be so much fun and extremely trippy. (Tekken or Jumping Flash, both would work well with this stage)
