Oshawott

Oshawott is a water-type Pokémon who appears in Mystery Dungeon Gates to Infinity Animated Trailers, part 1 and part 2.

Oshawott is a bipedal, mammalian sea otter-like Pokémon. It has furs covering its entire body, with white fur on its face and arms, light-blue fur on its chubby torso and a dark blue tail, feet and ears. It also has a tan-colored scallop shell attached to its stomach called a "scalchop," which is made of keratin (the same substance as human hair and fingernails). If broken, its scalchop can regrow.

Oshawott are mostly mischievous and slightly aggressive. When they feel bored, they will play with their Scalchop, making a "pound" sound.

Oshawott's scalchop can be removed from its belly and used as a sword for specific attacks, such as Razor Shell, and can also be used to deflect attacks.

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 battle and cracking hard berries. If heavily damaged or lost, Oshawott can grow new ones from its body, though it can take weeks.
