SCENE 2 - FIRST EGG: The boy picks up the red egg and carefully opens it with both hands. Inside is a small cute animated yellow toy car. The toy car suddenly comes to life, its wheels move, its headlights blink and it drives slowly in a small circle around the children. The children laugh and react with excitement. SCENE 3 - SECOND EGG: The girl picks up the blue egg and opens it. Inside is a cute little animated dinosaur toy.
