Scoria Dragon (DragonVale)

The Scoria Dragon is an Earth/Metal hybrid dragon in the game DragonVale.

In-Game Description
''Near the Mines of Dramoria, the Bessemer Wastes are home to the often overlooked scoria dragons. They are so overlooked, in fact, that our wizards accidentally classified them as the wrong type of dragon. Ooops. In their later years, scoria dragons grow rocklike scales on their back, but don't let their appearance fool you; they're still fast as can be when racing other dragons. ''
