In another Russian variant, "Иванъ царевичъ и Марья Маревна" ("Ivan Tsarevich and Marya Marevna"), collected by Ivan Khudyakov (ru), the young Ivan Tsarevich takes his sisters for a walk in the garden, when, suddenly, three whirlwinds capture the ladies. Three years later, the Tsarevich intends to court princess Marya Morevna, when, in his travels, he finds three old men, who reveal themselves as the whirlwinds and assume an avian form (the first a raven, the second an eagle and the third a falcon). After a series of adventures, Ivan Tsarevich and Marya Moreva marry and she gives his a silver key and warns him never to open its respective door. He does so and finds a giant snake chained to the wall.
