After a tornado in Kansas causes a loose gate to knock Dorothy Gale unconscious, she re-appears in the Land of Oz with Toto (Oz), and encounters a talking Signpost (voiced by Jack E. Leonard), whose three signs point in different directions, all marked "Emerald City". They later meet Jack Pumpkinhead (voiced by Paul Lynde), the unwilling servant of antagonist Mombi - cousin of the deceased Wicked Witch of the West. Toto chases a cat to a small cottage where Dorothy is captured by Mombi's pet crow (voiced by Mel Blanc) and Mombi (voiced by Ethel Merman) herself. Pumpkinhead sneaks into the house in Mombi's absence, and discovers her creation of green elephants, to use as her army to conquer the Emerald City. Pumpkinhead frees Dorothy, and they flee. After finding Dorothy gone, Mombi threatens that their warning the Scarecrow (Oz) will not help when her green elephants "come crashing through the gate".
