4 boxes to use however you wish. You may stack them inside or on top of each other, or cross them. Once you've decided the layout, the boxes stay put. NO CHANGING BOX SIZE. After that, you may add walls inside them, or delete any inside walls you may have created by crossing the boxes, and half walls and fences outside them. NO CC please so it doesn't yeet out when we tour. You may add foundations and change the wall height! #SaurusBoxShell #shellchallenge
