SHELL CHALLENGE! The rules are very simple: turn this weird box into a real build! It can be a house, a park, a gym, or whatever else you want! The only rule is to NOT TOUCH MY WALLS. The shell has to stay the same. You can add interior walls, windows, etc. and change the wall height, but DO NOT TOUCH MY EXISTING WALLS. Literally do anything you want except touch my walls. Thank you. Post to the Gallery with #simsieshell4 #lilsimsie #BG #BASEGAME #BaseGameOnly
