Gastrodon (West Sea)

Gastrodon appeared in 2006 video game called Pokémon Diamond & Pearl. Gastrodon is a Sea Slug Pokémon. If West Sea Gastrodon loses a part of its squishy pink body, it can regenerate. It sometimes comes forth from the seas to wander on land, and no one really knows why.

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.
