Ozma wants to whip up a snack but has never baked. Dorothy shows her how to make cookies. But Dorothy accidentally grabs the Potion of Life instead of the vanilla and pours it into the mixing bowl! The hand-mixer spins to life, magically mixing things together as it whizzes around the room -- half Scarecrow, half Tin Man. Oh my! The mixer spins out of the palace, mixing everything in its path! Half piggy, half munchkin! Dorothy and Ozma realize the only way to reverse the mix-up is to reverse the spell. They must use the mirror to change the Potion of Life into the Liquid of Petrification.
