Maususpin

Maususpin is an Electric/Cosmic-type Pokémon introduced in Generation Neo-I.

It is not known to evolve into or from any other Pokémon.

Biology
Maususpin is a small, rodent-like Pokémon that is surrounded by a rotating, Saturn-like ring. Maususpin is a small Pokémon, and as such does not have the strength to command the ring, so it grabs the ring from the inside and hangs there, slumped over the top of the ring. It can, however, maneuver this ring to attack. It is yellow in color, with light pink accents, including the electrical sacs located on its cheeks.

Triva
Maususpin may be based off of an Alabama Beach Mouse and ringed planets, such as Saturn.

Maususpin appears to be directly based off of the Japanese term maususpin, literally meaning "mouse spin". It also sounds like mouse and spin.
