It’s an undead baby dragon, produced by a failed magical spell. It probably would be cute if it weren’t partially decayed.

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.

The Boy Who Wouldn't Grow Up never had a chance. He was the victim of a deliberate sacrifice of a large cohort of hatchlings for the express purpose of attempting the dark magic required to turn a dragon into the dreadful abomination known as a Zombie. Boy was an extremely intelligent youth, and worked out what was going on before the end. But being only a hatchling, he was powerless to stop it. His bitter anger at the situation is the only emotion that really carried across into his afterlife, and he channels it into creating elaborate plans to take down the leaders in the cave. Luckily, he has so far not succeeded.
