Aww... It's a cute baby dragon. It occasionally shoots small puffs of smoke from its nose, like it's trying to breathe fire.
And look! It's grown its wings! It must be close to maturing.

Young dragons are relatively defenseless. Their scales don't grow in until right before they mature, and they have almost no strength. Once a hatchling's wings grow in, it marks the beginning of maturation. At this point they are usually left alone by their mother and begin to hunt and survive on their own.

Elop is a harmless dragon. He was frozen by an evil wizard, so he will never age, thus looking like a hatchling forever.
