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. More flowers appear on its back whenever it feels comfortable, but when it senses danger, it rapidly hides them again. Its legs are short and its underside is plump. Shaymin is one of the shortest Grass-type Pokémon. 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 wherever it lands. Shaymin is also attracted to areas where there is a lot of gratitude. Land Forme Shaymin has a shy personality and is easily scared. It also exhibits the behavior of scratching itself with its 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 observed to like sweet food. Forms Shaymin has two forms it can change between: Land Forme and Sky Forme. In Sky Forme, it has a slender, canine-like appearance. 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. The blooming of Gracidea flowers confers the power of flight upon Shaymin, transforming it into its Sky Forme. It reverts to Land Forme at night or if it is frozen. Sky Forme Shaymin has a courageous, energetic, and playful personality. It spreads feelings of gratitude when it takes flight. Sky Forme Shaymin has a deeper voice than Land Forme.
