Aww... It's a cute baby dragon. It enjoys swimming in a nearby pond.
And look! Its fins and tail have gotten bigger, and you've moved it to a larger body of water to swim in. 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.
