Mine Dragon (DragonVale)

The Mine Dragon is a Cold/Metal hybrid dragon in the game DragonVale.

In-Game Description
''One of the oldest known dragon types, the mine dragon spends much of its time deep underground in the cold Dramoria Mines. Because they are often seen running into walls while moving about, it was once thought that they felt their way around using their beards. We now know that they just have really poor eyesight. ''
