And look! It has grown wings! It must be close to maturing.
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 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 refuses to go to sleep when his parents tell him to. Instead he comes up with every excuse imaginable for why he needs to stay up. Someday he'll realize that his parents tell him to go to sleep because they need their rest, but for now he is just stubborn.
