L. Frank Baum 
The Patchwork Girl Of Oz 

The seventh book in the Oz series for children is The Patchwork Girl of Oz by L. Frank Baum. Ojo, sometimes known as Ojo the Unlucky, lives in squalor in the Munchkin Country of Oz’s forests with his sarcastic uncle Unc Nunkie. They go to see their neighbor Dr. Pipt, who has been working on making the mystical Powder of Life for six years and is ready to finish. After a number of misadventures, they come upon a large quadruple that consents to give them three hairs off its tail. They carry the Woozy with them since they cannot get rid of the hair.

Along the journey, they encounter Mr. Yoop, a 21-foot-tall man-eating behemoth, Jack Pumpkinhead, and the entertaining but unpleasant Tottenhots. The Shaggy Man guides them to the Emerald City where they meet Princess Ozma but informs Ojo that it is against the law to pluck a six-leaved clover there.

Dr. Pipt has lost his magical abilities, according to Ozma, who informs the group that he has been using magic outside the law. Ojo is given a new home close to the Emerald City by the Tin Woodsman, who refers to him as ‚Ojo the Lucky.‘
