One night, two big tooth worms walked into the little monkey's teeth and prepared to settle down here. One tooth worm said to another tooth worm, "Let's settle down here! Another tooth worm said, "Good! Then, they picked up their tools and jingled. Soon, they made several holes.
One day, the tooth worm shouted happily and woke up the little monkey. The little monkey said softly, "Who are you?" ! Toothworm said, "we are toothworms, we are in your mouth!" The little monkey quickly said, "How did you get into my mouth?" Toothworm said, "who told you to eat a lot before going to bed and not brush your teeth?" So you brought us here. As he spoke, he jingled between the little monkey's teeth, and the little monkey jumped up in pain and kept barking. Mother monkey said to the little monkey, "It's all because you don't brush your teeth."
From then on, the little monkey never dared not brush his teeth again.
