Strange shadows and the discovery of new evidence
Adding some sort of mystery to the scene, there was Tim, trying to unlock some unknown artifact. He tried for hours and hours, but nothing seemed to work. The thick reinforced walls of the little box would not dent a single millimeter when thrown against the floor, not even when beaten by an enormous hammer. There was something special about his box. It seemed so fragile when they first saw it, lying on top of the brown and reddish pile of rocks. They thought at first it was a jewel box, but later discovered it was something remarkably different and odd. They were enchanted by the mystery of the box and with the unusual figure they saw behind some bushes near the river.
They were uncertain about telling their parents or any other adult. They wouldn’t understand. So they decided to take up the challenge; to uncover and solve this strange chain of events by themselves. And they did.
Dinosaurs suddenly appeared.
