By the shore of Buyan, the merchant ships have left, and Gvidon laments having being separated from his father ("Veter po moryu gulyayet" = "The wind blows over the sea").
The Swan-Bird will help him by changing him into a bumblebee.
He will be able to fly over the sea, as a stowaway on Saltan's ship, to visit him (incognito) in Tmutarakan.

Interlude — Flight of the Bumblebee
Scene 2
The sailors arrive at Tmutarakan from their visit to Buyan.
 The sailors tell Tsar Saltan of the wonders of Gvidon's island (the magically appearing city itself, a magic squirrel, and the thirty-three bogatyrs from the sea).
The two older sisters are concerned that the Tsar will become interested in visiting the island, and they try to dissuade him.
In retaliation the bumble-bee Gvidon stings each of them in the brow.
Babarikha then tries to trump the sailors, by speaking of a fabulous Princess on the sea, at which point Gvidon stings her in the eye and blinds her.
Saltan decides to visit the island, but, in view of the havoc caused by the bumblebee, forbids that breed of insect from ever entering the palace again.
