Bird Man Skeleton is one of the many skeletons that could be found in the Vault of Bones. He was gotten inside of what seemed to be a chest, but it turned out to be a coffin. One it was opened by Flame Princess, he began screaming "Take my place! Take my place!," but was then shoved back into the coffin and burnt to ashes.
Bird Man Skeleton appeared to have a body made out of bones. His body was in the shaped of a large bird. He had a long, curved neck that led up to his humanoid skull.
- It could be assumed that he was forced into the box when he found it in his living form, because he wanted Flame Princess to take his place.
