Using this VTech Switch & Go Dinos Egg is super easy. First, open the eggshell and take out the up to 15 pieces inside. Then start assembling them to build your Dino. Once it's built, you can switch it into a vehicle in just a few simple steps. And vice versa! When playing, be careful not to lose any small pieces as they are easy to misplace. If the light effects, fun phrases, or sound effects stop working, check the batteries. Make sure to use the right type of batteries as recommended in the product. To keep it in good condition, wipe it with a dry cloth regularly. Keep it away from water and rough handling to avoid damage. Enjoy collecting all 4 different Dinos and have a great time Switch & Go!
