This hatchling appears to be... dead?

Perhaps not. It seems to be active during the night.

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.

This hatchling was forced out of its egg prematurely.

BBBBBLLLLLOOOODDDD is a special dragon. She was born with strange markings on her<br/>eggs, and when it hatched all the dragons thought she was dead. So they just let her rot in the corner of the cave. BBBBBLLLLLOOOODDDD isn't really dead. She's just only active at night. When the dragons are asleep she drinks their blood so she can live forever. The other dragons still don't know a thing.
