This is a baby toy. I used it for about six months. The remote control and mayonnaise are removable, so I think your child will enjoy it. The mayonnaise has a small stain on the back, as shown in the photo. The batteries are included, so both the main unit and the remote control are ready to use immediately. Please consider it. #Peaple #Yaritaihoudai (Play All You Want) #Toy
