Lisbet, the little witch, has a visit from witch child Trixi. For her visit, Lisbet conjures up a flying carpet, declares Trixi a witch princess, and flies with her into the full moon night. Faster than any witch's broom, they zoom over mountains and valleys. At some point, Trixi gets hungry and needs to pee, but that's no problem for Lisbet. It's only when the moon hides behind the clouds that Lisbet is at a loss for the first time.
