Once upon a time, there was a big bull. He lived on a farm with his new friend, a little bird. They liked to play together all day long.
One day, they saw a big rock near the farm. The bull and the bird had an idea. They decided to play a new game with the rock.
The bull would rock the big rock with his strong head, and the little bird would fly and sit on top of it. They played this game all day long and had lots of fun. The bull and the bird were very happy to have each other as friends.
