Your first step is to grab yourself a rake and pickaxe, then flatten out your area you want to dig.



You'll eventually be unable to lower anymore, thats where the pick comes in. Grab that badboy and just Rip and Tear that ground.

The rake should allows you to dig lower down now. You may need to add a few more potholes. Protip, you can change the distance of the rake using scroll wheel.



The same effect can be used to dig sideways, into the earth, just be aware that the roof can be finicky and you may have trouble with the RED SQUARE.

After a bit of fun, you can now destroy your plot to your desire.
