Piranhas Don't Eat Bananas (With CD)

The title of the book clearly tells readers that "piranhas don't eat bananas", but at the beginning of the story, Brian, a happy piranha, holds a banana in his mouth and sells to his companions, "Would you like a banana?" Everyone. I think there is something wrong with Brian's brain, because in addition to bananas, Brian also wants everyone to try water chestnuts, peas, plums... "We are piranhas! We eat meat, not vegetables and fruits!" "How do you know if you haven't tried it? What? The fruit is really delicious!" Just like the classic story "Green Eggs and Ham", the piranhas finally tried the fruit platter prepared by Brian. What will be the result after eating Xilihulu? Have the piranhas fallen in love with fruits since then?
