Shellos

Shellos is a slug-like Pokémon whose appearance changes drastically depending on where it is found. However, both forms have a shell-like back and an amorphous lower body. Both forms also have yellow lining around their eyes, mouth, and back.
In the West Sea form, the underside is white and its shell is pink. The shell has several small spike-like protrusions on it. On its head is a ring of pink fleshy knobs resembling flower petals that spike up.
In the East Sea form, the underside is green and its shell is blue. The shell has two flap-like protrusions. These flaps are lined in yellow. On its head are two white-tipped knobs resembling horns that extend away from its face.
Shellos and its evolution Gastrodon are examples of allopatric speciation, though the two forms are still able to interbreed (the child takes the mother's form or the father's if bred with a Ditto). If it is pushed or squeezed, a mysterious purple fluid will ooze out of its body. In the anime, West Sea Shellos can extend their necks to incredible lengths. It is unknown if the East Sea form can do this as well. Shellos live along the sea shore.
