The Dunwiddle Magic School is intended for children whose magic is "upside-down" like Dory (who turns into a combination of a kitten and dragon) and Pepper (whose uncontrollable "fiercing" terrifies everyone around her)--so the Show Off, where fifth grade students are supposed to showcase their skills, does not really seem like a good idea.

Abby, her two friends Robin and Frankie, and the annoying Penny, are in their treehouse arguing about what to do for their special school project when a tornado appears out of nowhere, scoops up the treehouse, and transports them all to the land of Oz, where they are soon confronted by Wicked Witch of the East (who is very much alive, and rather angry), and must save a story that is going completely sideways--all because of the evil Gluck.
