Penkoon

Penkoons are bulky, part-penguin, part-raccoon soldiers that patrol areas in Wario Land: Super Mario Land 3. When Wario comes too close to them, they'll make the spiked ball in their stomachs pop out. Despite their horned helmets, Wario can jump on them; however, they should not be charged head on because of their stomach-mounted maces.
