This hatchling appears to be... dead?

Perhaps not. It seems to be active during the night.

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.

Her name is actually Supercalifragilisticexpialidocious.

Unfortunately Sprclfrglstcxpldcs's owner couldn't find the room on her scroll to write down Sprclfrglstcxpldcs's true name, and had to take out all the vowels in Supercalifragilisticexpialidocious to fit it. Because of this, strangers often have trouble pronouncing Sprclfrglstcxpldcs correctly. Just insert the correct vowels and it's clear as day.

No one actually takes the time to decipher Sprclfrglstcxpldcs's personality. She doesn't really give them a chance to either, always yelling at them to "REMEMBER MY NAME AND PRONOUNCE IT CORRECTLY!" Just judging from this, it's easy to guess that this dragon is not pleasant to be around. And that's all anyone knows about her, to be honest--she's a jerk.
