Dorothy, Toto, the Shaggy Man, Button-Bright, and Polychrome come to the peculiar town of Foxville, where anthropomorphic foxes live.

With prompting from King Dox of Foxville, Dorothy deduces that she and Toto are obviously on another "fairy adventure" that will ultimately lead them to the magical Land of Oz, just in time for Princess Ozma's royal birthday party.

The king takes a particular liking to Button Bright, whom he considers astute and clever due to his tabula rasa-like mind.

Upon reaching the Land of Oz, Dorothy and her companions are warmly welcomed by the mechanical man Tik-Tok and Billina the Yellow Hen.

They proceed in company to come in their travels to the Truth Pond where Button Bright and the Shaggy Man regain their true heads by bathing in its waters.

They meet the Tin Woodman, the Scarecrow, and Jack Pumpkinhead who journey with them to the imperial capital known as the Emerald City for Ozma's grand birthday bash.

As preparations for Ozma's birthday party are made, the guests include Dorothy, Scarecrow, Tin Woodman, Cowardly Lion, the Wizard of Oz, Jack Pumpkinhead, the Sawhorse, Tik-Tok, Billina, Jellia Jamb, Woggle-Bug, Hungry Tiger, the Good Witch of the North, Shaggy Man, Button-Bright, Polychrome, and characters from all over Nonestica such as Santa Claus, a band of Ryls, and a bunch of Knooks from the Forest of Burzee, Queen Zixi of Ix, the Queen of Merryland, four wooden soldiers, and the Candy Man from Merryland, the Braided Man from Boboland's Pyramid Mountain, the Queen of Ev, King Evoldo, and his nine siblings from the Land of Ev, King Bud and Princess Fluff from Noland, and John Dough, Chick the Cherub, and Para Bruin the Rubber Bear from Hiland and Loland.

After everyone has presented their gifts and feasted at a lavish banquet in Ozma's honor, the Wizard of Oz demonstrates a method of using bubbles as transportation by which to send everyone home.
