In the mushroom kingdom, King Borovik XVI had a daughter Belyanka, who was in love with Gruzd. But the King does not agree to marry her and sends herald Dozhdevik to declare a decree about the search for the groom. The mushrooms are going to the palace: the handsome Flyfinch, the smart Valuy and the rich Dubovik. Borovik has an enemy - a warlike Tsar Pea. Tsar's Adjutant Pod arrives with a message: either Borovik will give Belyanka as wife for Pea, or he will ruin the whole mushroom kingdom and all the mushrooms will be pickled, dried and marinated.
