Slowpoke is a mostly pink Pokémon that doesn't look much like a water type Pokémon at all. It stands on four legs, and has a long tail that is used like a fishing pole. It's mouth is a pale brown color.
Slowpoke can have the abilities Oblivious or Own Tempo. Oblivious prevents Slowpoke from being infatuated. Own Tempo prevents Slowpoke from being confused. Although slow, Slowpoke is skilled at fishing with its tail, and it does not feel pain if its tail is bitten. It is also implied that their tails can grow back if it is cut off or removed (either during battle, fishing, and/or occasionally by human's).
Slowpoke evolves into Slowbro at level 37. Slowpoke evolves into Slowking when traded while it holds King's Rock. In the anime, Slowpoke's evolution is quite different. To become Slowbro a Shellder must latch onto Slowpokes tail. To become Slowking a Slowpoke must put on a King's Rock and have a Shellder clamp onto it.
