Quarry (Works!) by gamemachine32

A simple quarry system that digs blocks underneath it. Steps: 1: Copy The Command into A command block block and run it. 2: take a spider spawnegg and an anvil out of your inventory. 3: name the spawnegg 'quarry' on the anvil  4: spawn the egg. it should create a hopper. then place a block of coal on top of the hopper (remember to set CommandBlockOutPut to false. or else there will be lots of text spamming the screen!) then wait about 12 seconds. after that it should have shot out a lot of dirt and stone blocks. dig underneath the surface and see that the quarry has dug a square underground!
