They're a breed of dragon. In this case, a "pillow dragon."
You can typically figure out what egg will grow into what dragon by the egg's description - and appearance. Although a few eggs share the same description.
"Electric sparks dance across the surface of this egg." will get you an electric dragon - not to be confused with a thunder.
"This egg has a velvety texture." is a pillow dragon.
"This egg has strange markings on it" could result in an ochredrake, skywing, or horse dragon, best figured out by the appearance of the egg, but if it's from the cave then you won't know until after you pick it up.
It's a Hellfire Wyvern. xD I don't understand what you want to know. o.o
A dragon... doesn't have a BSA... I would say they're a bit uncommon, but not terribly so. Perhaps borderline.
Give him some love and I'll give you some back! xD If this guy ever makes any Thunder egg babies, I'll give it to anyone whom requests it. Though I promised someone else would get the first one.
