Thumper

Thumper is used in the recipe for the Soniclocator. The Soniclocator builds up energy in the goop that is in these thumpers, which was collected from the Enderslime mob. Using the power of the Enderman teleportation without the hassle of the creature itself to transpose the item you want with a piece of gravel (since this takes the least amount of energy in our tests to move!)
