Shaymin

Shaymin is a small, white hedgehog-like Pokémon. In Land Forme, it has green grass-like fur on its back and a pink flower with two leaves on each side of its head, which resembles the Gracidea flower. Several Gracidea-like flowers also appear on its back whenever it feels comfortable, but when it senses an impending danger, it rapidly hides it back. Its legs are short and its underside is plump. Shaymin is the smallest Mythical Pokémon to date.

In Sky Forme, it has a slender, canine appearance like that of a small reindeer. The fur on its back becomes a mohawk, and it has a red flower petal on the left side of its neck, resembling a scarf or cape. It has flat, white ears resembling wings, a small tuft of fur on the front of its neck, and a stumpy tail. Shaymin will change into Sky Forme and back if it touches a Gracidea. It reverts to Land Forme at night or if it is frozen. Shaymin can instantly purify any polluted area of all impurities in the air and transform it into a lush field of flowers. It takes in the polluted air, purifies it inside its body, breaks it down into water and light, and releases the purified substance in a violent, explosive burst. Its power varies based on the type of pollution absorbed. Shaymin can also communicate with telepathy and sense the gratitude of others.

Each season, Shaymin gathers with others in a flower field somewhere and migrates from there. This behavior is called Flower Carrying because a new field of flowers grow where it lands. Shaymin is also attracted to areas where there is a lot of gratitude. Its personality is almost opposite with each form: in Land Forme, it is shy and easily scared, while in Sky Forme, it is courageous and playful. If wet, it shakes itself to dry itself off, and exhibits the behavior of scratching itself with a hind leg. Shaymin lives in fields of flowers. Since it camouflages by curling itself up, it can easily escape people's notice. It has been seen liking sweet food. Shaymin is the only known Pokémon to know Seed Flare.
