Quox is a dragon from the other side of the world, and a descendant of the original dragon. Although Quox is young, by dragon standards, he is very large. At the time of his encounter with Betsy Bobbin and company, he was a mere three thousand fifty-five years old. His body is a lovely sky-blue color and thickly set with glittering silver scales, each as big as a serving tray. His head and face are not especially ugly for a dragon, but his eyes are so large that it takes a long time to wink. Whenever he smiles, he shows sharp, terrible teeth. His nostrils are large and wide, and his breath smells of brimstone. His voice is a little gruff, but not unpleasant. An electric light is attached to the end of his tail.
