Emerald City of OZ

The Nome King plots his revenge against the Oz people, who narrowly defeated him in "Ozma of Oz." Working with the help of Guph, an invasion specialist, the Nome King and his troops tunnel under the Deadly Desert with the aim of enslaving the people of the Emerald City. Dorothy, the Tin Woodsman, the Scarecrow and their friends fear the worst, as Princess Ozma insists on finding a non-violent solution.
