Having kids with Patchy.

I watched on of the game changer videos and while I hadn't tried; the video said it is possible because you try to take patch into CAS and change him, he will just appear as a bald sim at first. Plus you can unlock the outfit. I think that is why it is possible.

Mine hadn't came to life yet, so my sim just tried telling jokes and he would acknowledge them; but he hadn't left his post. I think he only comes alive during harvestfest. Not too sure.
