After Harvey arrives to help her with a class project but they spend the day goofing off instead, Sabrina's aunt lecture her on procrastination, so she tries to whip up a recipe for magical jumping jelly beans as a quick substitute for motivation. Unfortunately, she cuts corners on the recipe and produces a giant beanstalk in the back yard. When Harvey eats one of the beans, he is whisked to the top of the beanstalk where the Wicked Witch proceeds to fatten him up for her gourmet meal of the week. Sabrina attempts to rescue him, only to find that her powers don't work atop the beanstalk; and Hilda and Zelda, going to the emergency ward in the Other Realm for help, find themselves in an interminable waiting line. So it's up to Salem to conquer his fear of heights and help save Sabrina and Harvey from winding up on a platter.
