Input: Passage: The concept of the movie is explained in a voiceover intro by G. W. Bailey, who wonders what it would be like if one of the 1930s/1940s Rex O'Herlihan movies were to be made today. At that point, in a scene reminiscent of The Wizard of Oz, the cinematography shifts from black and white to color and the soundtrack changes from mono to surround sound.
As a consequence of this paradigm shift, Rex O'Herlihan, a "singing cowboy", is the only character aware of the plot outline. He explains that he "knows the future" inasmuch as "these Western towns are all the same" and that it's his "karma" to "ride into a town, help the good guys, who are usually poor for some reason, against the bad guys, who are usually rich for some reason, and ride out again". Rex's knowledge is also connected to the unspecified "root" vegetables he digs up and eats.
On his high-stepping horse Wildfire, Rex rides into the town of Oakwood Estates, walks into a saloon and meets Peter, the Town Drunk. In exchange for a free drink, Peter explains the background: the town, and especially the sheep herders ("nice enough, but they smell God-awful"), are being terrorized by the cattle ranchers, headed by Colonel Ticonderoga. Also there is Miss Tracy, the traditional Prostitute with a Heart of Gold. A local sheriff is "a corrupt old coward who takes his orders from the Colonel". 
Question: What does the only character who knows the plot outline ride to get around?

his high-stepping horse Wildfire.
