In a certain kingdom, in a certain state, there lived Tsar Anton. And he decided to marry his son, Ivan Tsarevich. But Ivan did not like any of the brides, and then the tsar got angry, ordered to blindfold the prince and give him a bow and arrows. The arrow sent by the prince hit the swamp hummock where the frog was sitting. Ivan handed her an engagement ring — and then a miracle happened: the frog turned into a beautiful girl, Elena the Wise.
