Using this T - Rex is super easy! First, let your imagination run wild and start creating your own Jurassic World adventures. When you want to make the T - Rex get angry, just slide the button on it. This will change its eyes from calm to an angry look. To make the T - Rex thrash its head, move the tail from side to side. Moving the tail up and down will change the dino's position. And when you press the trigger on the tail, it will do a cool chomping action. As for maintenance, keep it away from sharp objects to avoid scratches. If it gets dirty, you can use a damp cloth to gently clean it. Also, since it's for kids aged 3 - 8, adult supervision is recommended during play to ensure safety.
