Once upon a time, there was a little boy named Tim. He had a big brother named Sam. Sam was very intelligent. They both loved to play together. One day, they found a big, round rock in their yard. Sam told Tim to rub the rock.
Tim listened to his brother and started to rub the rock. After some time, they heard a strange noise. They were scared, but Sam, being intelligent, knew they should keep rubbing the rock. So, they kept rubbing it together.
Suddenly, a big, friendly dog appeared! It was magical! The dog wagged its tail and licked their faces. The boys were so happy. They played with the dog all day long. The big, round rock had given them a new friend.
