Polly wants to throw the ultimate pool party but soon learns that family is more important than looking cool in front of your friends when her attempts to be in two places at once turns disastrous for both the pool party and her Dad's pitch.

After Shani mistakenly blames Polly for using the locket's power to get an unfair advantage in the science fair, Shani impulsively throws her own project into the trash - and now the girls must retrieve it while staying one step ahead of Griselle.
