Using this Optimus Prime T - Rex toy is super easy. For kids aged 3 and up, to switch between the two play modes, just push the button on the figure. You can quickly change it from a Tyrannosaurus Rex to a robot and back again. To add some excitement, press the button on the back of the T - Rex. This will make it start chomping with cool lights and sounds. Also, notice the rescue drill on the figure. Press the relevant button, and it will spin in both T - Rex and robot modes. When it comes to safety, keep small parts away from younger kids who might put them in their mouths. To maintain the toy, keep it clean by using a dry cloth. Avoid exposing it to water, as it might damage the electronic components that make the lights and sounds work. And remember, the other toys in the Dinobot Adventures series are sold separately, so you can collect them one by one as they're available.
