It's the day before the farewell party for the teachers, and the girls are worried that they won't have enough time to prepare for it. They're also worried that there's no piano in the hall, so they're going to have to play the piano behind the curtain. The girls are all excited about the piano, but they don't really know what to do with it. The piano is the only thing they've got, so the girls decide to have a dance to celebrate the end of the school year.
