The second tier of Ground Zapper allows you to completely change the founding building blocks of the first world.
Not only can you now remove Soil blocks, but Moonstone - the Baserock - is now no longer a problem to shift either. This allows you to build even higher, by digging deep so you can start a tower (for example) as low as possible.
Sandstone can also be removed from the Canyon.
