The Bratz diamonds rollin runway is a big Red truck that has Bratz on the side and opens up to make it a runway. It lights up and is supposed to play a bunch of songs although it only plays one and you can plug it into your stereo to play music for your show. I don't understand what the difference would be then just having the stereo playing in the background and ours never worked anyways. As soon as my daughter opened this I had concerns with how it was going to hold up and I should have taken it right back. The doors constantly fall off and once we opened the truck it would never shut again and also the top 2 pieces that are supposed to latch keep falling off. My daughter can not play with this at all because it just keeps falling apart so basically the sides of the doors and whole top is off so it is just half a truck with wheels. I finally put it in the trash last week it was the worst $90.00 I have evver spent I have seen toys at the dollar store that are built better.
