Part of the floor will disappear, leaving three platforms above water. Avoid touching the drilling machine in the water or you will take damage. As for the boss, he will make a wave coming, and you shall jump on the wave and slam the cat idol on his head. Whenever he draws back, he will send out some purple spikey enemies, which will cause Balloon Wario on contact and result in time loss. After losing half of HP, the cat idol will be destroyed. Continue the same sequence, except you shall now stomp his bald head, and he will send red enemies dealing direct damage. Also the waves will move faster.
