Kabumpo in Oz
Ruth Plumly Thompson
 During Prince Pompadore of Pumperdink's eighteenth birthday celebration, his birthday cake explodes, revealing a magic scroll, a magic mirror, and a doorknob. The scroll warns the prince that if the he doesn't wed a "proper princess" within seven days, his entire kingdom will disappear. The prince, along with the kingdom's wise elephant Kabumpo, set off on an adventure to the Emerald City so Pompa can marry Princess Ozma, the only "proper princess" the Elegant Elephant can think of as worthy of his prince. Meanwhile, Ruggedo the Gnome King (Thompson "corrected" Baum's spelling of "Nome") finds Glegg's Box of Mixed Magic while tunnelling under the Emerald City. After he brings a wooden doll, Peg Amy, to life, and makes Wag the rabbit the size of a man, Ruggedo turns himself into a giant. This means that Ozma's palace gets stuck on his head, and in a panic he runs off to Ev with it. After many adventures in the strange lands of Rith Metic, the Illumi Nation, and the Soup Sea, Pompadore and Kabumpo arrive in the Emerald City to find Ozma missing. They set off to find her and eventually meet up with Wag and Peg Amy. The group reaches the edge of the Deadly Desert and is hijacked by the Runaway Country, a piece of land that has feet. It carries them over the desert to Ev. Eventually, Peg Amy is revealed to be a princess, and Pompadore marries her.
