Operation Uh, or A Bride for Gorynych

The queen gave birth on a remarkable night to a daughter, or rather, two - the beautiful Vasilisa and the Serpent... from the underworld! All the princesses are lovely: one is as graceful as a swan, the other has such... a character that any suitor would fall at her feet like a stone statue. Father Guidon thought of a clever plan to marry off the sisters together, and the dowry - half a kingdom for both. The matchmakers gathered - and the villain Gorynych took and kidnapped Vasilisa! The Serpent girl is not timid: she took foreign princes, the Clear Falcon Finist, a northern ranger as her companions, set up a navigational ball of yarn - and set off to rescue her sister. New Year is around the corner, the path to Gorynych's lair is long, and the protectors of the princess are peculiar. But how can there be no miracle on New Year's Eve?
