Sea Otter Pokémon
Oshawott is a Water-type Pokémon, No. 501 in the National Pokédex, introduced in Generation 5 (Unova region).
« This Pokémon from the Unova region uses the shell on its belly as a weapon to cut down its foes. Thus, I've conferred upon this shell the name ”scalchop”. »
Oshawott is a small biped like a young sea otter, with a white head and turquoise fur. It carries a pale-yellow shell, the scalchop, on its belly.
It uses the shell like a knife to fight, crack berries, and strike back. It evolves into Dewott, then Samurott.
In "In The Shadow of Zekrom!", Ash's Oshawott leaves Professor Juniper's lab, saves them from Team Rocket, and joins the team.
Yusuke Ohmura designed it last: the line follows a samurai and Japanese culture. Oshawott may blend ocean, shell, water, wash, and otter.
