On the day of the departure of the school's field trip, Yeonhong asks Yonhap to buy him some food ingredients for making new chocolate. He also wants to make new fig powder and barbary fig paste for the festival. Yonhap agrees to buy the ingredients. He tells Yonhap that he wants to console his mother, who is upset that he has to go on the field trip with the robot. He says that she had planned to tag along with him on the trip, but she was caught by Yonhap's mother taking a walk in the morning. The robot is sent to school, and Yonhap tells his mother that he is required to report on the situation. He then tells her that there is a message from the vice president, saying that he will be sure to find out the secret of his vice president during the school trip. He asks where he can go during his free time, and he is told to take route 7 and wonang falls. He is also told that there are souvenir stores in the city, and that he should buy some citrus chocolate instead of buying a souvenir. He wants to buy a large rock statue of a rabbit, which is made of real stone. He notices that the head of the statue is shaped like a sitting rabbit's head, which he will buy on the day before the trip.
