Mania and Amanda are visiting Barbara. Bibi rushes clanking through the window right into the middle of the cake. Unfairly, she gives Kartoffelbrei (her witches' broom) the fault for the miserable landing. Her father Bernhard forbids Bibi to work magic and shuts in the broom. Then it disappears. No trace of the broom! Aunt Amanda guesses that Kartoffelbrei might be flown away.
