Action Puzzle title in which you must guide Mario (or Yoshi, or Princess) under the spell of Wario (and wearing a bucket on his head for good measure) through the dangerous hazards of the level. This is peformed by manipulating the environment as in Lemmings, but later levels give you a scan of the situation and then you have to frantically work out a plan in advance of the bewitched Mario. Devious, but fair as you'd expect from the big N.
