Spoink is a gray-colored, piglike Pokémon with dark, circular eyes, stubby arms, a large grey nose, and small ears. Spoink is most notable in that it leads an unusually fragile existence. It possesses no hind legs and motion is achieved by bouncing on its spring like tail. However, the bouncing serves a far more vital function in that it keeps its heart beating; if it's stopped from bouncing, it'll go into cardiac arrest and die. It also wears a pearl produced by a Clamperl on top of its head to amplify its psychic powers. However, if it loses the pearl, it begins to weaken, so Spoink is in constant danger from either ceasing to bounce or losing its pearl.
