...a zase ta Lucie! (1984)

Osvald, stripped of the honor of being the leader of the children's party, prepares a terrible revenge. Lucie will be amazed when he takes possession of her Ferdy and Ferdy plasticine characters and slips her artlessly made imitations, stripped of all magic, in exchange. He's coming for her on her birthday. But everything at home is upside down. The children's comedy is a direct follow-up to Lucie, postrach ulice (1984).
