With this All-Out Attack Tyrannosaurus Rex, the most iconic of all species gets a stomp attack and is ready for battle. The stomp attack of this action figure consists of a dramatic up and down movement of the head, accompanied by a biting movement and roaring noises. The faster the button is pressed, the stronger the roar and bite. This T-Rex is also "ready to fight" with teeth that almost double in size. Scan the hidden track code in the free Jurassic World Play app on a compatible smart device (Android or iOS, not included) to activate a digital version of the dinosaur and gain access to cool games. Subject to variations in colour and design.
