Piplup is a Water-type Pokémon introduced in Generation IV.
It evolves into Prinplup starting at level 16, which evolves into Empoleon starting at level 36.
Along with Turtwig and Chimchar, Piplup is one of three starter Pokémon of Sinnoh available at the beginning of Pokémon Diamond, Pearl, and Platinum.
Piplup has a strong sense of self-pride. Because of its pride, it has a hard time accepting food from humans and bonding with its caretakers. It will even puff out its chest after it falls down, which it often does due to its poor walking abilities. However, it is a skilled swimmer that can dive for over ten minutes in order to hunt. It has also been shown to fly short distances in the anime. It lives along the seashore in colder climates.
