Oshawott - Unova

Oshawott is a Water-type Pokémon.
It evolves into Futachimaru starting at level 17, which evolves into Daikenki starting at level 36.

Oshawott is a bipedal sea otter-like Pokémon, primarily light blue, dark blue, and white in coloration. Oshawott has a rounded, spherical white head, with small, triangular dark-blue ears to the sides. Oshawott's eyes are large, dark, and ovoid in shape; its dark-orange nose is shaped like an oval on its side. Oshawott also possesses speckles to the sides of its face, most likely meant to be a stylistic implication of short whiskers in the common manner of cartoon canines, and light blue bubble-esque features composing a "collar" around its neck. Oshawott's torso is light blue, and decorated with a pale yellow seashell feature in the center. Made out of keratin, this appendage can be removed and used in various ways; mainly, as a weapon. Its small, digit-less and somewhat rounded arms are white in coloration, with its feet—having, unlike its forearms, discernible digits—colored dark blue. Oshawott also possesses a slightly plank-shaped dark blue tail and a pair of fangs unseen until it opens its mouth.
It can fight skillfully by detaching the seashell-shaped appendage on its belly. This shell can be used for a variety of different things, such as a acting like a weapon, shield, and boomerang.
If Oshawott is attacked, it will fight back using its shell attachment without any hesitation.
