Catbat
Catbat is the fifth boss in the Game Boy Advance game Wario Land 4 and also the guardian of the Sapphire Passage. Catbat resembles a large purple cat with no legs and a bat sticking out of its head. Since this monster has the features and wings of a bat, Catbat can fly in the air.
Catbat's battle area has a pool of water in the floor. In order to defeat the monster, Wario must ride on the waves Catbat creates when it crashes into the pool; all the while Wario must avoid the spiked objects that Catbat spits out. If Wario touches one, he will become Puffy Wario and float up costing precious time. When Catbat is low on health, the bat head disappears and the spiked objects become red. This time, they will hurt Wario (instead of transforming him). When on the newly undulating wave, Wario must jump off and stomp Catbat's head. After enough hits, Catbat is defeated and Wario is rewarded with the creature's bracelets.
