I see, I think I will get Lava instead Bone
Then I must double my dragon's habitats to get every pair [/QUOTE
My suggestion is to just give it a try! It doesn't hurt anything and you will then know your answer for sure. Just a suggestion also would be to buy a Hibernating Cave to keep some of your dragons in. Not sure if you have this yet or not. Best of luck to you in your Dragonvale game.
