It’s an undead baby dragon, produced by a failed magical spell. It probably would be cute if it weren’t partially decayed.

Young dragons are relatively defenseless. They are born with relatively soft scales, which are shed and replaced with harder ones as the hatchling matures. Once a hatchling’s wings grow in, it typically marks the beginning of maturation. At this point they are often capable of hunting on their own and are usually left alone by their mother.

Zombonedraco, the hatchling that once decided to clean Emeraldvinedraco's tombstone. Bad decision. The only thing he wishes in life is that he HAD A FOURTH FOOT! Until he gets wings, he isn't able to move much, and that depresses him.

Strangely, he is the only one who seems to understand Psydraco's drawings, and is very worried about them, and Psydraco doesn't want to draw them, but something possesses her when she draws them, and Zombonedraco is the only one to see that.
