She weakens her enough to make her lose her voice, right before the school musical auditions. Meanwhile, Cameron creates his own club called "The End Hunger Today Club" as an excuse to eat hot wings all for himself, but when Fletcher catches him in the act and threatens to tell the teachers about his fake club, Cameron is forced to let Fletcher join. When Cameron has to earn money to keep the "The End Hunger Today Club" alive, Fletcher makes flyers stating that Oprah supports their cause.

Olive then moves into Chyna's locker in order to avoid the ghost, but ends up annoying Chyna (by rearranging her lunches and making up stuff like meat-rollups, putting balls in her locker, and revealing her crush on a boy to the boy) to the point where she devises a scheme to make Olive face her fears.
