Sliggoo is a gooey purple snail-like Pokemon. The top part of its body is a lighter shade of purple than its underside. Sliggoo has four long feeler-like horns atop its head and pale green spots lining its neck. When evolving from Goomy, Sliggoo's eyes devolved (resembling the green spots that Goomy had on its cheeks), so it is blind and must use its four feeler-like horns as a radar system to sense sounds and smells, as it lacks ears, a nose, and the ability to see. It has tiny stub-like arms on its deep purple underbelly, and a gooey snail-like shell on its back that seems to be part of its gelatinous body.
