Shaymin

Shaymin is a small, hedgehog-like Pokémon with two distinct forms: Land Forme and Sky Forme. In its Land Forme, it is primarily green and white with a grassy back and pink flowers on each side of its head. In its Sky Forme, Shaymin resembles a small, white reindeer with green fur on its back and a red flower on the side of its head. Known as the Gratitude Pokémon, Shaymin has the ability to purify polluted areas and transform into its Sky Forme when exposed to the Gracidea flower. It is a Mythical Pokémon with a gentle nature and is associated with themes of gratitude and environmental harmony.
