Gastrodon (East Sea)

Gastrodon appeared in 2006 video game called Pokémon Diamond & Pearl. Gastrodon is a Sea Slug Pokémon. Color variations between a Gastrodon from different habitats have intrigued scientists for some time. Research is under way to find out what happens when a blue East Sea Gastrodon is moved to western seas.

In its West Sea form, the flower-like crest it had as a Shellos has now turned into horns adorning the side of its head, which point directly upwards in a crescent moon shape. Its underside up to the bottom of its mouth is pink, its back and the top of its head is completely brown, and it has two small protrusions on its back with several pink spots dotted around them. It also has two small protrusions on its neck underneath the horns, and it has a yellow border running down its body from its head, separating the brown and the pink coloration.
