To celebrate 85 years of the wonderful Wizard of Oz, John Henson is in the lab's atmospheric chamber measuring the velocity of tornado desserts so that the bakers can honor Dorothy's rough trip to Oz. Then, the bakers visit the acid pit, where the spirits have been melting things. Inspired by those who have melted before, especially the Wicked Witch of the West, the bakers make melted witch desserts to appease the spirits, as well as judges Carla Hall, Zac Young and Stephanie Boswell.
