The narrator introduces us to a new member of the household: a cat named yaoyao. He explains that the cat is a reincarnation of a moon bunny, and that the owner of the moon bunny can only change from a rabbit to a cat when the owner eats the "moisture pill" that the bunny has made. The cat is so excited to meet his new friend that he doesn't even bother to pat her belly. He and the other cats go off to school together. When they arrive at the school, they find that the equipment is set up in such a way as to make it difficult for the children to play with the cat. When the cat sees that the children are playing with the equipment, he becomes furious and attacks the children.
