Piplup

Piplup (ポッチャマ, Potchama, Pochama) is a fictional creature in the Pokémon media franchise.

Creature description
Piplup is a small blue penguin. According to the Pokédex, it lives along shores in northern countries. Its thick down guards it from the cold in such climates. It is a skilled swimmer and is able to dive for over 10 minutes at a time to hunt. It is naturally proud and prideful, and as such hates accepting food from people even when domesticated.

Piplup is one of the three starter Pokémon that a trainer can recieve from Professor Rowan in Pokémon Diamond & Pearl. Piplup resembles a small blue bipedal penguin. Piplup's second evolution is Prinplup, who eventually evolves into Empoleon. In the anime, Dawn chose Piplup as her starter Pokémon after she rescued it from a group of giant Ariados. Piplup had trouble accepting Dawn as its trainer, but eventually began to trust her. Dawn uses Piplup to fight in both battles and in contests.

As a Poké Ball Pokémon
Piplup makes an appearance in Brawl. Piplup uses its surf attack to glide across the stage. Any character that gets caught in Piplup's surf will get washed away with it. The simpler the stage's terrain is, the greater the affect of Piplup's glide will be. Piplup's attack is used basically the same way as Marill's attack.

As A Trophy
Piplup also appears as a collectable Trophy in Brawl.
