This gives you a mining turtle to spawn in your world. Place him down and he will dig a 5x5 tunnel and put all the items in a chest he will create. This has a really cool animation, as the arms on the turtle seem to really mine and the items roll across the floor to the chest! To sum it all up, the chest he puts it all in is a double chest, with 81 item slots and 2 of these double chests!
