Dungeon

Dungeons are rooms found underground. They can be recognized by mossy cobblestone flooring and cobblestone walls. Dungeons have mob spawners in them, which can make them dangerous to enter. Fortunately, they may have chests in them as well, which can contain items (though a chest also has a chance of being empty). The items in these chests can be as useless as cobblestone or as valuable as diamonds. The chest may have some cookies or cocoa beans, which can't be planted and can be found only in dungeon chests.
