They become jealous of their younger sister. When the tsar goes off to war, the tsaritsa gives birth to a son, Prince Gvidon (Gvidón.) The older sisters arrange to have the tsaritsa and the child sealed in a barrel and thrown into the sea. The sea takes pity on them and casts them on the shore of a remote island, Buyan. The son, having quickly grown while in the barrel, goes hunting. He ends up saving an enchanted swan from a kite bird. The swan creates a city for Prince Gvidon to rule, but he is homesick, so the swan turns him into a mosquito to help him. In this guise, he visits Tsar Saltan's court, where he stings his aunt in the eye and escapes. Back in his realm, the swan gives Gvidon a magical squirrel. But he continues to pine for home, so the swan transforms him again, this time into a fly.
