Oshawott is a bipedal sea otter-like Pokémon. It has a spherical white head with small, triangular dark-blue ears on the sides. Oshawott's eyes are dark, and its dark-orange nose is shaped like a horizontal oval. Several freckles cover its cheeks which may be premature whiskers, and two pointed teeth can be seen when it opens its mouth. The light blue fur on its body forms bubble shapes around its neck. Its arms are white and rounded, while its feet are dark blue with three toes each. It also possesses a rudder-like dark blue tail. It carries a pale yellow seashell called a "scalchop" on its belly.

This shell is made of the same material as its claws and is used for both battles and cracking hard berries. Oshawott wields the shell like a knife. It uses the scalchop to block the moves of its enemies before slashing back at them in swift retaliation. Oshawott learned to how maintain its scalchop with riverbed stones by copying the humans it observes using whetstones. If the scalchop is heavily damaged or lost, Oshawott can grow a new one from its navel. It has been recently seen living in the Terarium of Blueberry Academy.
