Once upon a time, there was a mighty and helpful dinosaur called Trexi in the Cretaceous era. 

Trexi used to live near a huge volcano. He liked to help other dinosaurs if they were in trouble. And that's why all dinosaurs liked him and were kind to him.

There were all types of dinosaurs but the Pterodactyls were the meanest of all. They often stole the dinosaur eggs and gobbled them up!

Nobody could ever catch them as they were the only dinosaurs that could fly.

One sunny morning, a mama Stegosaurus was looking at her egg and was waiting impatiently for it to hatch. 

Then suddenly the Pterodactyl came and was almost going to steal it away. Trexi was passing by and saw the Pterodactyl snatching the egg. Trexi quickly grabbed his neck.
