Location: Central Plaza, Cap Kingdom
Phase 1: Topper will spin around, throwing his hats. Dodge the hats. When he stops spinning, he'll be vulnerable. Jump on his head. He'll lose one hat.
Phase 2: He'll add more hats and spin faster. The strategy remains the same: dodge, then jump on his head when he's vulnerable. He'll lose another hat.
Phase 3: Even more hats and faster spins. Continue dodging and jumping on his head. Three hits will defeat him. The key is patience and timing your jumps to avoid his hats and land on his head when it's exposed.
Reward: Multi Moon
