If Dorie, Reanne and Mirabelle pass The Wandawhirl Test, their combined powers used in Perfect Harmony, will equal that of a full-fledged witch! And that means, they could defeat Patunia and reverse the power of her magically monstrous pendants! But there’s only one problem! The girls have to take their exam in the Lunaverse-and they can only get to the Lunaverse through the back door of Patunia's Mystery Wind Magic Shop! After a series of absurd attempts to break into the shop, the girls finally make it-only to arrive in the Lunaverse too late for the test! The Witchlings return defeated and find Patunia's pendants causing epidemic injury and illness.  It's up to the girls to work their magic before it's too late!
