Wailmer (Japanese: ホエルコ Hoeruko) is a Water-type Pokémon introduced in Generation III.
It evolves into Wailord starting at level 40.
Wailmer, along with Azurill and Kecleon, was one of the first Generation III Pokémon revealed, in early March 2001.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
