Because her mother is ill and resting in the country, Xiaoyue and Xiaomei live in the country with her father and visit her mother. One day, when Xiaomei was playing in the yard looking for acorns, she accidentally saw the little totoro. The little totoro wants to get rid of Xiaomei, but she leads Xiaomei to the sleeping big totoro, which makes both Xiaoyue and Xiaomei excited. One rainy night, when Xiaoyue's sisters were waiting for the bus at the station where Dad came back from work, my totoro appeared. Abortion lent it an umbrella, but it was considered a very interesting toy. My neighbor totoro gave abortion and Xiaomei acorns, which made abortion and Xiaomei very happy. Abortion, they also saw the cat bus that my neighbor totoro took.

At the end of summer, abortion and Xiaomei received a telegram from the hospital. Their mother is not feeling well, and the two sisters are very worried about her illness. Xiaomei complains that her sister doesn't care about herself, and her sister blames Xiaomei for not being sensible. Xiaomei cried and called her sister an idiot and ran away. Abortion hurriedly looked around for Xiaomei.

It was getting late, and Abortion thought of asking my neighbor totoro for help. My neighbor totoro called the cat to have an abortion by bus, and finally found the lost Xiaomei. After that, the cat bus took the two sisters to the mother's ward window. Seeing that everything is safe from afar, the two sisters don't know how happy they are. Xiaomei gave the corn to her mother, hoping that she would recover soon.
