TINY SHELL CHALLENGE! The rules are simple: DO NOT TOUCH MY WALLS. You can change this shell into anything you want, including tiny houses, tiny gyms, etc. Just keep the shell the same! Do not add any exterior walls or tiles. You can add walls inside to make floorplans, just keep the shell the same on the outside. It is a shell challenge! I'll tour them on Twitch on Monday! Use #simsietinyshell for me to see :) #jodelsuomi
