Aww... It's a cute baby dragon... except for the tangle of dangerous-looking vines surrounding it...
Now there are even more vines. Perhaps something is happening?

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.

Tundra Vine somehow ended up in the far north, in the frozen tundras. Trying to burrow into the frozen ground, this dragon managed to survive, but became frozen in the process.
