Oshodani is a sea otter who appears as a supporting character in the anime Papuwa. He is one of the namamono, the community of strange talking animal creatures who live alongside the human characters on Papuwa Island and take part in the island's everyday life.

His personality centers on drumming. Oshodani is searching for the perfect drum, and he is driven by an obsession with beating on anything he can find. Because of this, he always carries a pair of drumsticks with him and treats virtually any surface or object as a potential instrument. He enters the story as a wandering drummer sea otter, and his free-spirited, single-minded fixation shapes nearly everything he does.

His main motivation is the quest for the perfect drum. This goal defines his behavior, and his constant drumming reflects both his dedication to that search and his impulsive nature. As a performer, he is able to produce rhythms from whatever is available to him. When a situation becomes hostile, he uses his drumsticks as weapons, attacking by throwing them at his opponents.

Within the story, Oshodani is one of the many eccentric residents who make up the island's absurd community. His appearances place him among the namamono who come into contact with the central characters, and his drumming habit tends to create noise, distraction, and comedy in the scenes he shares with them. He is a familiar presence rather than a central figure in any of the main conflicts.

Oshodani receives little in the way of personal development over the course of the series. His role stays consistent: he remains the drum-obsessed sea otter whose search for the perfect drum and habit of striking anything within reach give him a clear and unchanging identity in the cast.
