Heavy Mole is a boss that debuts in Kirby's Adventure. It is a large, golden machine with a single eye, a missile launcher on its backside, and two extendable, mechanical arms with red spiked attachments on the end of each which allow it to dig through the ground with ease. On its back are two spinning turbines and a pair of smoking tailpipes. The missiles it launches are also cycloptic. Heavy Mole's battle strategy is to dig a tunnel using its arms while firing missiles behind itself.
