In this chapter, we learn that the song is about a little girl named hidagiyu, who is a popular character in the town. The song's lyrics are a mixture of nursery rhymes, nursery rhymes about little girls, and a nursery rhyme about a bird named "Turtle." The song is based on the song "Turtle," which is sung by a kindergarten teacher named "Cobra." The teacher tells the students that the bird "really likes you," and the students respond by praising the bird.
