Make up a fairy tale of 250 words.

Once upon a time, there were two kinds of bacteria, one called Qingqing and the other called Honghong.

A comfortable home, but also the illusion of getting something for nothing. So, these two bacteria were hidden in an unpackaged snack. The owner of this package of snacks is a little boy named Lele. When he began to pour snacks into his mouth, Qing Qing and Hong Hong took the opportunity to blend in. Diary diary 100 words

Two bacteria began to eat two holes in Lele's front teeth, because the holes were small and Lele didn't feel anything.

I didn't brush my teeth after eating, so I left some snacks between my teeth. This makes Qing Qing and Hong Hong very happy. They were full, and the hole couldn't hold them any more, so they doubled the hole.

Finally, one day, Lele's teeth suddenly and violently hurt. Suddenly, he found a vertical toothbrush and a tooth on the countertop in the bathroom.

"Please let me help you get rid of the pain!" Said the toothbrush, comforting him in a gentle voice. Then the toothbrush rolls up and down with the body, brushing out rich foam with toothpaste, and then rinsing with clear water. At this time, bacteria can't resist the impact of water flow and are washed away by toothpaste foam. After brushing her teeth for a few days, Lele's teeth stopped hurting.

Lele learned his lesson and fell in love with the good habit of brushing his teeth in the future.
