Ojo is a character from the fictional Oz book series by L. Frank Baum. He first appeared in The Patchwork Girl of Oz. Ojo is a Munchkin who lived with his uncle, Unc Nunkie in the Blue Forest, a remote location in the north of the Munchkin Country. During a trip with his uncle to visit his uncle's friend Dr. Pipt, Ojo learns from Pipt's wife, Dame Margolotte, that he is known to others as "Ojo the Unlucky." Ojo discovers rationalizations for this, including the fact that he was born on Friday the 13th, is left-handed, and has a wart under his arm, and he begins to believe that bad luck follows him wherever he goes. However, the Scarecrow officially deems him Ojo the Lucky after hearing these reasons because he believes Ojo's bad luck is due to a self-fulfilling prophecy.
