Catbat

Catbat is the fifth boss in the Game Boy Advance video game Wario Land 4. Catbat is also the guardian of the Sapphire Passage. A strange-looking creature, Catbat resembles a large purple cat with a bat sticking out of its head. Since this monster has the features of a bat, Catbat can fly in the air.

Catbat's lair has a pool of water in the floor. In order to defeat Catbat, Wario must ride on the waves Catbat creates when the strange creature crashes into the pool, meanwhile avoiding the spiked objects that Catbat spits out. Should Wario touch one, he will become Puffy Wario and float up, which will cost time. Whan Catbat is low on health, the bat head disappears and the spiked objects become red. This time, they will hurt Wario. When on the wave, Wario must jump off and stomp Catbat's head. After enough hits, Catbat is defeated.
