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.

Vampirica Algida grew up with no teeth. She was so ashamed that she asked to be frozen. She sits in a corner all day listening to Antsy Pants singing her favourite song:

"I am a vampire

I am a vampire

I am a vampire

I have lost my fangs

So I'm sad and I feel lonely

So I cry and am very angry

And I ate some garlic

So I am no more satanic yeah yeah"

It doesn't actually cheer her up, but she finds it soothing.
