Mob Spawners are at the heart of Dungeons. They spawn Mobs inside the Dungeon. Mob Spawners can be destroyed by the player but they can not be picked up. Traps can be placed around the Mob Spawner to kill Mobs that are spawned (Such as drowning them) so that what they drop can be harvested.

Skeletons, Spiders and Zombies can be spawned from Mob Spawners found naturaly in the world. A Mob Spawner can only spawn one type of Mob.
