Here is the MARCH Shell Challenge by zefrine! I created a gym!! Here are the rules: Put these pieces together to make a building! Any lot size can be used. You can rotate, but do not change the size or shape! No other buildings allowed. You can change existing walls to half walls or fences, but do NOT delete walls when rooms are joined. Wall height CAN be changed. Decks can be added. No Cc. #ZefBroken
