Chiyo, in her capacity as class president, asks the class what they want to do for the upcoming cultural festival. Yukari says that conventional and orthodox ways mark the death of intellect, and Chiyo comes up with a suggestion box. A stuffed animal exhibition is drawn from the suggestion box. Kimura attempts to give his own suggestion but is silenced by Tomo. Chiyo introduces her dog, Mr. Tadakichi, to Sakaki, who becomes content when she pets him and is awed to see that Chiyo can ride him. On the day of the arrival of the cultural festival, Tomo wears a cat suit and runs around the school in it to advertise the exhibition. Throughout the day, Sakaki helps students buy stuffed toys from the exhibition. After the cultural festival, Yukari's class celebrate on their huge success.
