Prinplup/Pottaishi is the evolution of Piplup. Prinplup resembles a blue penguin. It has yellow three-toed feet. Its body is mostly light-blue. There are four button-like spots on its stomach. Its wings are dark-blue with light-blue tips. It apparently has claws hidden in the flesh of its wings because it can learn the moves Metal Claw and Shadow Claw. Prinplup's wings deliver wicked blows that snap even the thickest of trees. It has an owl-like face and two yellow crests running across the top of its head. It searches for prey in icy seas. It lives alone, away from others, because every Prinplup considers itself to be the most important, so they can never form a group.
