Item Request: Kid's Toy Plushie

Hi there! I'm introducing the game to my kid, and she's very upset that the Sim version of her can't have her favorite plushie, which is a clownfish. I tried making one myself in Blender, and got it into S4S, but couldn't figure out how to get it from there into my game. I'm sure someone with more experience will make it look better than I did anyway. There are a couple of pics below. 

I'd be extremely appreciative (and I know my daughter would be too) if anyone is willing to help me out.
