The shaggy man asks Dorothy for the road to Butterfield, inadvertently drawing her into a bewildering maze where ordinary Kansas roads dissolve into countless strange paths. Accompanied by her little dog Toto, Dorothy sets out with the shaggy man, who carries a mysterious Love Magnet that compels every living creature to adore him. Along the way they encounter Button-Bright, a little boy lost in the woods whose head has been carelessly transformed into a fox head by King Dox in the wonderful city of Foxville. As they press forward through valleys and rocky plains, they are joined by Polychrome, the Daughter of the Rainbow, who fell from her father's arch during a dance and became stranded on earth.
The travelers face severe perils, notably escaping the clutches of the Scoodlers, two-faced cannibals whose removable heads serve as dangerous projectiles. After crossing the Deadly Desert in a sand-boat constructed by the industrious Johnny Dooit, they finally reach the yellow country of the Winkies in the Land of Oz. Seeking relief from their magical afflictions, the shaggy man and Button-Bright bathe in the Truth Pond, which successfully restores their natural appearances. They are soon joyfully reunited with old friends, including Tik-tok the clockwork man, the Tin Woodman, and the Cowardly Lion.
The journey culminates in the grand Emerald City, where Princess Ozma prepares a magnificent birthday celebration. Guests arrive from distant realms, including Santa Claus, Queen Zixi, and King John Dough, joining an extraordinary gathering of fairy-tale figures. Following days of grand feasts, royal processions, and marvelous magical performances, Dorothy is transported safely back to her Kansas home by Ozma's Magic Belt, bringing a peaceful conclusion to her latest extraordinary adventure.
