Once upon a time there was a cat named Sue. She lived in the forest. Her garden was pine trees. the day she moved in she had a dream. In them she had a lamb to play with. It was white and cuddly.
One day the lamb fell off the tree. It was mad at his mom to let go up the tree.
In the end it was not really mad. It was just a dream.
Sue woke up and realized she needed a lamb. So she got one.
