“ But people do live there, just the same. The top of Mount Munch is shaped like a saucer, broad and deep, and in the saucer are fields where grains and vegetables grow, and flocks are fed, and brooks flow and trees bear all sorts of things. There are houses scattered here and there, each having its family of Hyups, as the people call themselves. The Hyups seldom go down the mountain, for the same reason that the Munchkins never climb up: the sides are too steep.
In one of the houses lived a wise old Hyup named Bini Aru, who used to be a clever Sorcerer. ”

“ He had always wanted to get away from Mount Munch and visit the big world—especially the Land of Oz—and the idea now came to him that if he could transform himself into a bird, he could fly to any place he wished to go and fly back again whenever he cared to. It was necessary, however, to learn by heart the way to pronounce the magic word, because a bird would have no way to carry a paper with it, and Kiki would be unable to resume his proper shape if he forgot the word or its pronunciation. ”

“ Once a year there was a festival on Mount Munch which all the Hyups attended. It was held in the center of the saucer-shaped country, and the day was given over to feasting and merry-making. The young folks danced and sang songs; the women spread the tables with good things to eat, and the men played on musical instruments and told fairy tales. ”
