Heavy Mole is the boss of Yogurt Yard in Kirby's Adventure. It is one of very few robotic Kirby bosses, and also one of few bosses that does not appear in the anime.
King Dedede gave Heavy Mole part of the Star Rod when he tried to stop Nightmare from invading Dream Land. Throughout its battle with Kirby, it launches Dygclops from its body. The only game Heavy Mole appears in other than Kirby's Adventure and its remake is Kirby's Avalanche, where it is the 12th competitor.
