Oshawott is a bipedal sea otter-like Pokémon and is primarily light blue, dark blue, and white in coloration. Oshawott has a spherical white head with small, triangular dark-blue ears on the sides. Oshawott's eyes are large, dark, and ovoid in shape; its dark-orange nose is shaped like a horizontal oval. Oshawott also has freckles on the sides of its face, most likely intended to be a stylistic implication of short whiskers. Its body forms light blue bubble shapes around the neck area, composing a sort of "collar". Oshawott's torso is light blue, and decorated with a pale yellow seashell in the center. Made out of keratin, this appendage, called a "scalchop", can be removed and used in various ways, but mainly as a weapon. Its small, digit-less and somewhat rounded arms are white in coloration, while its feet, unlike its forearms, have discernible digits; they are colored dark blue. Oshawott also has a rudder-shaped dark blue tail and a pair of fangs that are unseen until it opens its mouth.
Oshawott uses its scalchop to open hard berries. Oshawott mainly live in water but may occasionally come to land to find food. If Oshawott is attacked, it will fight back using its scalchop without any hesitation. When eating, Oshawott uses its forepaws to move food to its mouth, rather than going down on all fours to eat it.
It can fight skillfully by detaching the scalchop on its belly. The scalchop can be used for a variety of different purposes, such as a sword, shield, and boomerang. It also uses it to break open hard berries. The scalchop grows from its bellybutton. [Source: Bulbapedia]
