The Road to Oz: In Which Is Related How Dorothy Gale of Kansas, The Shaggy Man, Button Bright, and Polychrome the Rainbow’s Daughter Met on an Enchanted Road and Followed it All the Way to the Marvelous Land of Oz. is the fifth of L. Frank Baum’s Land of Oz books. It was originally published on July 10, 1909 and documents the adventures of Dorothy Gale’s fourth visit to the Land of Oz.
While Dorothy Gale is at home in Kansas one day, she and her pet dog Toto meet the Shaggy Man who comes walking past the Gale farm. He is a friendly, yet slightly senile hobo with an optimistic, care free mentality. He politely asks Dorothy for directions to Butterfield, which is the nearest town on the prairie. The girl agrees to show him the way, bringing her dog with her. Further on, the road splits into seven paths. They take the seventh one and soon find themselves lost in what appears to be another dimension. The trio meets Button-Bright, a cute and wealthy little boy in a sailor’s outfit who is always getting lost. Later, the companions encounter Polychrome, the beautiful and ethereal Daughter of the Rainbow who is stranded on earth. Polychrome explains that she accidentally fell off her father’s bow while dancing on it. The bow ascended into the atmosphere and back into the clouds before she was able to climb her way back on it, thus being left behind.
Dorothy, Toto, the Shaggy Man, Button-Bright, and Polychrome eventually 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 magical Land of Oz, just in time for Princess Ozma’s royal birthday party, (which is now acknowledged as August 21 by Oz fans, even though the book only refers to the 21st of the month), Dorothy having mentioned that the current month is August in another passage. The king takes a particular liking to Button Bright, whom he considers astute and clever due to his tabula rasa-like mind. Believing that the human face does not suit one so clever, Dox gives him a fox’s head. A similar event subsequently happens to the Shaggy Man, when King Kik-a-Bray of Dunkiton confers a donkey’s head upon him — also in reward for cleverness, even though it’s implied that Foxville and Dunkiton exist at odds with one another.
