Using this Hot Wheels City Ultimate T - Rex Transporter is super easy. In hauler mode, grab the handle and pull it along. Any 1:64 scale cars in its way will be gobbled up. When you want to transform it, simply lower the tail. You'll then see it turn into a Robo T - Rex with cool lights and sounds. To have some racing fun, put the cars on the two - lane race track on its back or launch them from its mouth. As for maintenance, keep it away from sharp objects to avoid scratches. If it gets dirty, you can use a soft, damp cloth to clean it. Just make sure it's completely dry before storing it. And remember, since the colors and decorations may vary, each toy is unique!
