Tip builds a pumpkinheaded man as a joke. But the joke's on Tip when a mean old witch brings Jack Pumpkinhead to life!

Soon Jack and Tip-and their friend, the Sawhorse-are on the road to Oz. There they join forces with the Scarecrow and the Tin Woodman against the rebel army of General Jinjur, who has conquered the Emerald City.

If Tip and his friends defeat Jinjur, they can restore the throne to the rightful ruler-Princess Ozma. There's just one slight problem-they've got to find the princess first.
