Vullaby resembles a baby vulture. It has a plump, stout body covered in dark gray feathers, tiny wings with gray tips, and pink feet with three clawed toes. Its neck is short and supports a round, pink head devoid of any feathers, except for a crest on the top. There is a collar of fluffy, light gray feathers around its neck. It seems to be wearing a broken skull as a diaper-like undergarment, hence its species name. Vullaby either finds this bone itself or uses one found for it by Mandibuzz. Vullaby is known to chase after weaker creatures. Vullaby is a female-only species.
