Aww... It’s a cute baby dragon. It is clearly a water animal.

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 typically 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.

I BITE YOU often wonders why he's the only frozen hatchling in Nadat's cave. Everyone else seems to grow and age, and he stays young. He refuses to believe what Jiraiya the paper dragon says, that he stays so small because he spends all his time chasing the tails of other dragons and trying to bite them. After all, while a smaller size makes sneaking and nipping easier, surely, he thinks, his mindset can't be what's keeping him small.
