The girls are in the middle of a swimming lesson, and one of the girls slips her swimsuit. The other girl is shocked, because she's just seen two other girls leave the room. The two girls try to figure out what's going on, but they can't figure out who's gone. The girls decide to start by stretching, and the other girl presses the other one to do the same. The girl tries to get the other to stop, but the girl presses on her anyway, and she starts to get twitchy. She tells the other girls to stop and get away from her, and they run off to get help.
