Switzerland tells

A man lives with his daughter Wassilissa, two daughters-in-law and his second wife (in an old cabin/outside in the forest). The stepmother and her daughters are jealous of Wassilissa. She is subjected to harsh tests by her half-sisters, jealous of her beauty and her diligence at work. Facing adversity, a little doll helps him, made by his late mother. Someday, Wassilissa is sent into the forest with the formidable Baba Jaga to look for fire. Baba Jaga promises her on condition that she honors a few tasks. The doll advises her and helps her fulfill her duty, so that nothing is blamed on him. Help fulfill your mission., and Baba Jaga gives him a glowing skull in exchange . Once back home, she is first welcomed with joy, since fire and light were lacking since his departure. The skull with glittering eye sockets pursues mother-in-law and sisters-in-law and burns them to ashes. Wassilissa becomes, using her doll, an excellent weaver. Shortly, even the tsar entrusted her with the making of his shirts and went so far as to fall in love with her. They lived happily as tsars until the end of their days.
