Three Cheers for... Who?

When Katie takes an interest in cheerleading, Suzanne becomes jealous and starts her own squad, but just for the girls from class 4B. Katie isn't the only one annoyed. The 4B boys are so sick of the girls making up cheers, it looks like a full-fledged spirit war is about to break out. Then the magic wind strikes at the worst possible time, turning Katie into who else?-a cheerleader at the top of a pyramid.
