Clefairy

Clefairy is a Fairy-type Pokémon.

It evolves from Cleffa when leveled up with at least 220 happiness and evolves into Clefable when exposed to a Moon Stone.

Biology
Clefairy is a bipedal, pink Pokémon with a chubby, vaguely star-shaped body. A small, pointed tooth protrudes from the upper left corner of its mouth. It has wrinkles beside its black, oval eyes, a single dark pink oval marking on each cheek, and large, pointed ears with brown tips. A tuft of fur curls over its forehead, much like its large, upward-curling tail. Each stocky arm has two small claws and a thumb on each hand and both feet have a single toenail. There is a pair of tiny, butterfly-shaped wings on its back. Though incapable of flight, Clefairy's wings can store moonlight and allow it to float.

Clefairy is very shy and rarely shows itself to humans. On the rare occasions it does come down from its mountain home, it can be seen dancing under the light of the full moon. The area surrounding their dance in enveloped in a magnetic field. Once the sun starts to rise, it returns home where it sleeps nestled with other Clefairy. The anime has shown that Clefairy is actually an extraterrestrial Pokémon.
