This time it’s an earthquake that sets Dorothy off wandering into mysterious and strange countries. Dorothy, Eureka (her cat), Jim the cab-horse, and Zeb are all shaken up and sent hurtling into the earth, before arriving in the land of the Mangaboos.
There they run into both trouble and the Wizard of Oz. In a hot air balloon, of course.
During their adventures they run into Gargoyles, Dragonettes, the Braided Man, and other, well, weird stuff.
