What is the jingle of "I am a little monster"?

I am a little monster, carefree and at ease. Kill without blinking an eye, eat without salt. One mouthful of seven or eight will make your stomach burst. I went to the latrine to take a poop and remembered that I forgot to bring the paper.

This line comes from the movie "Nezha: The Devil Boy Comes into the World".

"Nezha: The Devil Boy Comes to the World" is directed and written by Jiaozi, with Lu Yanting, Jonson Cerf, Han Mo, Chen Hao, Lu Qi, Zhang Jiaming and Yang Wei as the main dubbing actors. The film is adapted from a Chinese mythology story and tells the story of Nezha's growth experience despite being "born as a devil" but "defying nature and fighting to the end".

The limerick of "The Devil Boy of Nezha Comes to the World"

1. Being locked up in the house with nothing to do, climbing over walls, smashing tiles and throwing bottles and jars. After going back and forth a thousand times, I was also very tired.

2. Life is full of tears, and the more you struggle, the more unlucky you become. Are you tired from the dying struggle? Why not lie down on the bed and sleep?

3. It is my mission to do justice for heaven, and I am best at slaying demons.
