The Crumble Horn is one of the rewards for completing the Quest Ram's quest. If the quest is completed, this (along with one of each of the resource blocks) will be given to the player by the Quest Ram.
When the Crumble Horn is used, blocks in the direction of the player will begin to crumble into other blocks. Stone crumbles into Cobblestone, which crumbles into Gravel, which will disappear from the world and will occasionally turn into a resource block of either Dirt or Gravel that the player can pick up. Additionally, Stone Brick and Mazestone will crack when exposed to this effect. The sound of a baaing sheep can also be heard emanating from the Crumble Horn when it is used.
