a very hard one to call as he had hair all over... just because he is called a dragon doesn't necessarily make him one, think of night tigers for example, they aren't tigers are they. to be honest i have no idea what id call him.
Its just like the question wether a griffon is a mammal or a bird lol.
for some more useless imaginary animal facts, did you know taun taun from star wars is suppose to be a reptile apparently! lol
