Ok so we have this guy called Ivory Dragon. Something just popped into my head- Why ivory? What does ivory have to do with dragons? Let's look at the possible explanations, shall we?
1, It's obviously a dead dragon. We know that ivory comes from elephants. So Ivory Dragon is actually a dead.... errm... elephant dragon? All hail inter-species breeding!
2, It's not named after what it was while living, but after the bones it is made of. So an Ivory Dragon is a bone dragon that is assembled from the bones of dead elephants, right? That said, it could be very possible to build a bone dragon from the bones of every kind of animals, right? Like, a mighty dead badger-hedgehog-bone dragon, right? Right?
3, Maybe the name has nothing to do with the origins, but it's all about where it lives(you know, lives, like a dead dragon usually does). For example, Leaf Dragon is clearly associated with the forest and the leaves of trees. So, our Ivory Dragon likes to chill... in an elephant graveyard?
Discuss.
(And don't even ask me about Light Dragon.)
