Titre original : Cleanup!
While clearing their personal belongings out of the club room, the girls find an old guitar that used to belong to Sawako. Since it had aged a bit, Sawako allows the girls to sell it and add the money to the club's budget. After visiting a home superstore to buy a storage shelf, they take the guitar to the music store where they are surprised to find it valued at ¥500,000. When Sawako inquires about the sale, Ritsu tries lying about its value, but it backfires when Sawako asks for a receipt and the club end up getting considerably less money. However, she allows the girls to buy one thing with the money. Noticing that Azusa looks a bit concerned about not having any freshmen to look after, the girls decide to get her a pet turtle named Ton.
