Love it!! We didn't have batteries needed for the fox, so I can't say what song it plays. But that's not a big deal. The set up was easy only took me 3 minutes to get it up and have my baby playing underneath. He seemed to have fun swinging his hands at the colorful toys and looking at the mirror, cooing. When playtime was over we just picked it up folded it in half and tucked it between the couch and wall so it is out of the way.We went to our local walmart and for a similar mat like this one it was $60 so I was so happy to find this one for so cheap on here!All in all, I am loving watching my baby learn and play on this so money well spent.
