Motion is achieved by bouncing on its spring-like tail. The bouncing has a vital function, in that it keeps its heart beating. Even while it is sleeping, it continues to bounce. It wears a pearl produced by Clamperl on top of its head, which amplifies its psychic powers. Spoink will be weakened without a pearl, and always searches for bigger pearls. In the anime it was shown to easily mistake other round objects as its pearl. It lives in mountainous areas. It likes to eat mushrooms that grow underground.
Spoink is a gray, pig-like Pokémon. It has dark, circular eyes, a large gray nose, and small ears. It has stubby arms and possesses no hind legs.
Spoink can be obtained by owning a level 25 Skitty. Its shiny form can be unlocked by reaching level 100 on Spoink.
