Fiona and Frieda's Girls United Troop 895 is on a mission to clean up the Forest Street Subway station. After they stray from the group, they find themselves totally, completely, hopelessly lost, just like Hansel and Gretel. They have to use their magic rhyming powers and enter the realm of fairy tales, as it's the only way to help Hansel and Gretel get home--even if the witchiest witch ever locks them in a cage, or worse!
