King Ka-Thunk is a large, spiky boss that rotates around a central pillar. Your goal is to hit the 'X' on his back. Wait for him to expose his back as he rotates, then run and jump to stomp on the 'X'. After each hit, he'll speed up and sometimes summon smaller Ka-Thunks. The Cat Suit can be useful for quickly climbing the pillar if you miss a jump. Three hits are required to defeat him.
