Carracosta resembles a bipedal, blue-colored sea turtle of some sort. Black, rocky structures encrust its face, back, and the sides of its chest, forming prongs on the "mask" and back, and somewhat pocket-like forms on the chest. Its flippers are long, with black fingers or fingerlike structures at the tips. Carracosta has rounded thighs, short legs, and two short black toes on each foot.
