Pengi (often mispelled Pengy) are a regular enemy in the Kirby games. Pengi is a fierce penguin. It has large eyes and bushy, spiky eyebrows. Its bill is sharp and small on top but the bottom half extends down over most of its front. Its underbelly is light while its back is darkly colored. A pair of flippers hang at its side with little bird feet beneath it.
Pengi slides around short distances on its belly as it waits for Kirby to get near. When he does, it opens its large mouth and blasts him with a cool breath to freeze him solid. Pengi is the only enemy that gives the Ice ability.
Pengi appears in other games. In each one, it exhibits the same behavior as it did in Adventure and grants the Ice power.
