Griffin

A winged mythical creature that Mombi transforms into to attempt escape from Glinda.

First named in The Marvelous Land of Oz, ch. 22

Fortunately, the ground where the tent had been pitched, being Just before the city gates, was hard and smooth; and while the Ant still crawled about, Glinda discovered it and ran quickly forward to effect its capture But, Just as her hand was descending, the Witch, now fairly frantic with fear, made her last transformation, and in the form of a huge Griffin sprang through the wall of the tent—tearing the silk asunder in her rush—and in a moment had darted away with the speed of a whirlwind.
