The plumbbob mobile has 3 channels, located in kids/misc. just like the sims 3 mobile. The neat thing about sims 3 that you can't do in sims 2 unless you want to recolor it, is the create a style tool, so you don't neccisarly have to go with the colors I have here, you can choose your own. I didn't change anything from the sims 2 plumbbob mobile, not even the textures. It's all the same. Ony thing I changed was channels, because of course you need those in 3.
So here it is:

Boys:
