Pottaishi

ポッタイシ

Prinplup is a blue, penguin-like Pokémon. Its body is primarily dark blue, featuring light blue markings on its face, wing tips, and lower torso. It has blue eyes and a short yellow beak with a small point situated above it. Two large yellow ridges run from its beak over the back of its head, meeting just above the nape of its neck. Four large white spots, resembling buttons, are located on its body. Rather than arms, it possesses long, sturdy, flipper-like wings strong enough to knock over and snap trees. It stands on short legs with yellow, three-toed feet.
Prinplup possesses a strong sense of self-pride, which keeps it from forming groups with others of its kind. This Pokémon inhabits icy waters, where it hunts for prey. It swims gracefully in cold seas. Its singing voice has been likened to a roaring tide.
