Vullaby resembles a baby vulture. It has a plump, stout body, tiny wings, and stumpy feet. Its neck is short and supports a round head devoid of any feathers except for an enormous crest on the top. It seems to be wearing a broken skull as a diaper-like undergarment, hence its species name.
Vullaby is a female-only species. Rufflet is regarded as a male counterpart, but is a separate species that cannot produce Vullaby Eggs.
Vullaby are uncommonly skilled at finding skeletons and using them as armor.
It has the tendency to use broken skeleton pieces, most likely skulls, as diaper-like clothing to protect its rump. It will chase after weaker creatures.
The Vullaby can be seen lurking by caves and grasslands.
