Location: Forgotten Isle, Lost Kingdom
Phase 1: Knucklotec, a giant stone fist, will slam his fists down, creating shockwaves. Dodge these. When he slams a fist, capture it with Cappy. Use the captured fist to punch his other fist. Repeat until both fists are damaged.
Phase 2: After both fists are damaged, he'll reveal his eye. Capture one of his fists again and punch his eye. He'll then regenerate his fists and become more aggressive, slamming faster and creating more shockwaves.
Phase 3: Continue the pattern: damage both fists, then punch his eye. Three hits to the eye will defeat him. The key is to quickly capture a fist and aim accurately while dodging his powerful attacks.
Reward: Multi Moon
