Joyce Kilmer Middle School is holding a fundraising carnival, and Jenny and her rival Addie make a bet that each girl will raise more money than the other. The loser will have to wear her pajamas to school! The competition gets even hotter with the arrival of a stylish new girl. Will she join Addie's group, the Pops, or will she help Jenny and her friends? Someone's going to be wearing bunny slippers to school; will it be Jenny?
