Jamano
Jamano is the ghost pirate boss who faces Wario in Wario Land 3. He fights Wario in The Stagnant Swamp. Upon entering his arena, four skull appear out of nowhere, and will sperate across the rooms corners. The room will turn pitch black, and all that will be visible will be Jamano, the skulls, and Wario himself. After the player moves Wario to the skull on the lower right, the ghost pirate will appear and begin chasing Wario. Wario must hit the lower skull, then jump up and hit the higher one. Wario must then go left and bash the left-most skull, then the right-most skull. Wario must repeat the process until Jamano is neutralized. If at any time Wario is caught by the boss, Wario will be hauled outside. Furthermore, the longer Wario waits after hitting a skull, the more likely it will return.
