Once upon a time, there was a little monster. The monster was light green and had big eyes. He lived in a dark forest with his family. The monster's name was Tim.
One day, Tim's mom told him to behave when they went out to play. Tim was a good monster, so he listened to his mom. He played with his friends, but he did not make too much noise or scare the other animals.
At the end of the day, Tim's mom was very happy. She said, "You behaved very well today, Tim!" Tim was proud of himself. He had a big smile on his face. From that day on, Tim always tried to behave, and he was a very good little monster.
