In the wake of losing the DoReMi Magic Shop, Dorie, Reanne and Mirabelle decide to refurbish an old broken-down bus and open a new store called The DoReMi Magic Bus-located directly across the street from Patunia’s re-vamped magic shop, now renamed The Mystery Wind Magic Shop.  But it seems that everyone-the Witchlings' classmates included-prefer Patunia's place! Word has it that Patunia's magical charms grant your wishes right away! When the Witchlings ask Patina why their charms don't work as well as Patunia's, Patina informs them, since Patunia is a full-fledged witch, her powers are greater. But when Patunia's customers suddenly suffer mysterious injuries and ailments, the Witchlings sense something's afoot!
