Bone Dragon (DragonVale)

The Bone Dragon is a limited dragon from the game DragonVale. It is not always available.

In-Game Description
''Bone dragons can only be found for a couple weeks during the year. The rest of the year it is believed that they burrow underground near cemeteries to be around other bones. But I bet if you breed one and put it in a habitat with other bones, it would stick around. Or perhaps near a heat source to keep away the bone-chilling winter cold? ''
