Summary Amanda has sent invitations to her birthday celebration on Mount Blocksberg. Unfortunately Barbara Blocksberg has got a bad cold and is unable to attend. Bernard doesn't feel like going although this time as an exception the witches' husbands have been invited, too. Bibi definitely wants to fly there. By chance Carla visits the Blocksbergs and hears about the celebration. A witches' celebration would make a sensational story. But Barbara says she cannot attend because strangers are not permitted. Carla, however, cajoles Bibi into casting a spell on her to make her invisible and then taking her with her. Unfortunately things don't work as planned and Carla is discovered. Fortunately the witches are clement and nobody is punished. But all the photographs that Carla has taken turn white.
