Mega Sponge

This mod adds a single block, THE MEGA SPONGE, in case you're tired of emptying large oceans and lava lakes with sand, flying machines, and the like. This block is responsible for emptying a large space; it can easily empty a monument. This sponge empties 31 blocks downwards and 31 blocks away to all sides except upwards, the following image shows how to use it correctly

You put the block, right click and empty it
