The Ash Dragon is an Lightning/Plant hybrid dragon in the game DragonVale.
The strange expression all ash dragons have was caused by a loud magical boomstick going off near one of their ancestors. It's said the BOOM! was so loud it echoed through time and affected ash dragons throughout the generations. That seems almost as unlikely as the dead rising from their graves!
The Ash Dragon can be bred by using any two dragons, in either order, containing the Plant and Lightning elements.
