Cleffa (Japanese: ピィ Py) is a Fairy-type baby Pokémon, and prior to Generation VI, a Normal-type.

It evolves into Clefairy when leveled up with high friendship, which evolves into Clefable when exposed to a Moon Stone.

Cleffa is a small, pink creature that is vaguely star-shaped in appearance. Its ears are completely brown. It has two small black eyes, a small mouth, and it appears to have a small, permanent blush on its cheeks. It possesses stubby, digitless arms and legs, which come to a point. It has a curl on its forehead and a curled up tail. Cleffa can also gain nutrients by drinking dew water. It has been known to be attracted by meteor showers, and sightings of this Pokémon always increase during meteor showers. When it does show up, it dances the night away. Cleffa lives in mountainous regions.
