Aww... It's a cute baby dragon. Ever since it hatched, the sky has been full of very dark clouds.
And look! It's grown its wings! It must be close to maturing. It's learned to use its new wings quickly and you now have a hard time keeping it on the ground.

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.

As Thor is a very young dragon, he can only create small thunderclaps. His tiny lightning bolts deliver painful, but harmless, shocks. He loves to zoom around the cave at high speeds, although, as he's still learning to use his wings, he occasionally hits a wall.
