One day Mombi visited a Crooked Magician called Dr. Nikidik, and purchased the Powder of Life from him, which she used to bring Jack Pumpkinhead to life. Tip created Jack to scare her, so as punishment Mombi brewed a potion that would turn Tip into a marble statue. That night, Tip ran away and took Jack with him. When General Jinjur's Army of Revolt conquered the Emerald City, Jinjur feared that the deposed Scarecrow would return with the Tin Woodman to take back the throne of the kingdom. Jinjur asked Mombi for help and she agreed, hoping to recapture Tip, who had joined the Scarecrow.
