It's another quiet day at Wario's castle. The sun is out, the gold is glistening, and Wario is in a peculiarly pleasant mood. That is until he tosses an evil gem into his pile of treasure. The result -- Wario's castle is turned into four unique worlds and his treasure made into unique (and rather ferocious) creatures. Oh, and poor Wario's out on keister. Say what you will about Mario's ultimate foil, but no one deserves to have their fortune turned into evil little creatures.

Now it's up to you, as the master of malevolence, Wario, to beat the gold out of the creatures inhabiting eight different areas. Only when all the treasure's been reclaimed can Wario hope to get his castle back. Sure he's an irascible bastard, but darnit if he ain't lovable!
