Once upon a time, in a faraway land, there was a big green Dinosaur named Rex. Rex loved exploring the jungle and was always looking for new friends. One day, while he was wandering through the tall trees, he spotted a little baby elephant named Ella. Ella had big floppy ears and a long trunk. She was lost and scared.

Rex approached Ella and asked, 'Are you okay? Do you need help finding your family?' Ella sniffled and said, 'I got separated from my mama. I'm all alone and don't know where to go.' Rex smiled kindly and said, 'Don't worry, little one. I'll help you find your way back.'

So, Rex and Ella set off on a grand adventure together. They crossed rivers, climbed hills, and even faced a mighty lion. But they weren't scared because they had each other. They laughed, played, and protected one another like best friends do.

After many days of trekking through the jungle, they finally found Ella's family. Mama elephant was overjoyed to see her little baby safe and sound. Ella hugged Rex tightly and said, 'Thank you for being my friend and helping me find my way back. I'll never forget you.' Rex smiled and said, 'You're always welcome, Ella. I'm glad we became friends.'

From that day on, Rex and Ella remained friends forever. They visited each other often and had many more adventures together. And in their hearts, they knew that true friendship is the greatest treasure of all.
