Tititi-Hoochoo the Great Jinjin, also known as the Private Citizen, is an enormously powerful immortal who dwells on the other side of the world from the Land of Oz.
He has a majestic and commanding appearance that excels the stately kings and queens who make up his court. His facial features are beautiful and dignified, his manner composed. His eyes are black, with sparks of red fire in their centers. He dresses in a white robe with a dragon emblem on his chest.
He can appear and disappear at will. His powers are poorly understood, but clearly immense. He rules a court a fairy kings and queens, who (like the Queen of Light) have responsibility for various aspects of human experience. The Great Jinjin alone does not have such a responsibility; he is qualified for his role of overlordship because he is, in this sense, a "private citizen."
The Great Jinjin has no heart, but instead possesses a high degree of reason and justice. Although he is merciless he never punishes without reason. (Tik-Tok of Oz)
The country ruled by the Great Jinjin is a lovely place. There is an immense castle surrounded by vistas of trees and shrubbery. The Hollow Tube has one end there, near a great marble fountain, and is tended by Tubekins.
L. Frank Baum may have derived the name Tititi-Hoochoo from Hiti-Hiti, who was king of Tahiti at the time of the H.M.S. Bounty mission at the end of the eighteenth century. (Both are rulers on the other side of the world.) Baum could adapt a name for a fantasy character from an exotic name in real life. In his story "The Pea-Green Poodle," one of the Animal Fairy Tales, the canine hero is called Pippo-Tib, a name that plainly derives from Tippu-Tib, an East-African ruler of the late nineteenth century.
Also, in reference to Tititi-Hoochoo, compare the name Titicontoo in "The Tiger's Eye."
