Heavy Mole

Heavy Mole is the boss of Yogurt Yard in Kirby's Adventure.

Heavy Mole digs through a large sea of dirt and will fire missiles that Kirby can inhale (the orange ones give Hammer, which can destroy the dirt in this game. The red ones give Sleep). In the fight against Heavy Mole, the camera focuses on him- so if Kirby gets off-screen, he loses a life.

Heavy Mole also appears in the game's remake.
