How to Spawn Imaginary Friend?

I don't know if there's a way to do it with MC, but this mod allows you to buy the Imaginary Friend from the toy section in Buy mode.

Edit: I think the sell function doesn't work on IFs that were already in your game. You need to use MC if you want to get rid of them.

@wendyyi1 sorry for the late response, had no wifi for a couple days. I will try that mod, hopefully I can get them to bond with my sims! I had a thing where I used MC to reset ownership of one of the dolls, but even when I set someone as the owner, it wouldn't come to life no matter how much she played with it. Thanks!

Late but with MC you can force a doll to be alive. If you still want I can try to look for the option path again!
