On her way down the yellow brick road, Dorothy attends a banquet held by a Munchkin named Boq. The next day, she frees a Scarecrow from the pole on which he is hanging, applies oil from a can to the rusted joints of a Tin Woodman, and meets a Cowardly Lion. The Scarecrow wants a brain, the Tin Woodman wants a heart, and the Lion wants courage, so Dorothy encourages them to journey with her and Toto to the Emerald City to ask for help from the Wizard. After several adventures, the travelers arrive at the Emerald City and meet the Guardian of the Gates, who asks them to wear green tinted spectacles to keep their eyes from being blinded by the city's brilliance. Each one is called to see the Wizard. He appears to Dorothy as a giant head, to the Scarecrow as a lovely lady, to the Tin Woodman as a terrible beast, and to the Lion as a ball of fire. He agrees to help them all if they kill the Wicked Witch of the West, who rules over Winkie Country. The Guardian warns them that no one has ever managed to defeat the witch.
