Continuity or not?

As a person who believes that a dragon is a fantasy creature, I have never really worried about my Baby Dragons having two tails, or four back legs, trying to show children that imperfections are not a problem in any world. After all Ray Harry Housen had two headed Dragons and many other fantastical creatures in his films.

It’s just a thought but providing it’s not supposed to be the same dragon, I don’t see why a fantasy dragon can’t have one or two tails, or four back legs.

Isn’t that teaching children that we are all a part of the same universe, I would find the whole writing fantasy a bit of a farce if we had to show everything as perfect.
