Väinämöinen, Ilmarinen and Lemminkäinen continue in their boat journey to Pohjola, however the boat runs aground on the back of a giant pike.Väinämöinen instructs Lemminkäinen to kill the pike but he fails, Ilmarinen mocks Lemminkäinen but he himself fails and his sword is broken to pieces. Lemminkäinen and Ilmarinen plead to Väinämöinen for his magical assistance and with his mighty sword cleaves the pike to pieces and scatters its bones and flesh over the landscape. Väinämöinen orders the pike's front portion be cooked and the bones be made useful, however nobody can find a use for fish bones so Väinämöinen endeavors to make a magnificent harp. After the harps construction is complete Väinämöinen summons a worthy player, many try to play but none can do the magnificent instrument justice. Väinämöinen himself sits down to play the harp, he calls to all peoples of Northland to listen and revel in his music. On hearing Väinämöinen's playing all of the creatures of the world—be they from air, earth or water—come to hear the beautiful music. Väinämöinen's music is so beautiful even the gods themselves come to hear it. All of Väinämöinen's audience begin weeping for the music, and soon Väinämöinen himself is weeping, his giant tears fall and flow to the water where they become magnificent blue pearls, more wonderful then anything on earth. Väinämöinen calls to a duck who is able to gather the pearls for Väinämöinen. The heroes land at Pohjola and are met by the hostess Louhi who asks them why they are there, Väinämöinen tells her that the people of Kalevala wish to have the Sampo. She responds by saying that it cannot be shared among all the heroes and as it brings great prosperity to Pohjola it will not be surrendered. Väinämöinen then says they will take it forcefully which angers Louhi and she summons soldiers to vanquish Väinämöinen and his people. Väinämöinen plays his harp which pacifies the people of Pohjola and causes them to fall into a deep sleep. Väinämöinen's heroes then go to find the Sampo, they reach the copper mountain and Ilmarinen anoints the hinges and bolts of the chamber and the bolts unlatch and the doors fly open. Lemminkäinen then enters the chamber and with swelling ego praises himself until he sees the beauteous Sampo, he tries with all his might to move it but the roots of the mountain have firmly secured its place. Lemminkäinen then captures and harnesses a great ox, he uses it to plough the roots and free the Sampo. Väinämöinen and the heroes carry the Sampo back to their boat and proceed to leave Pohjola and return home. Lemminkäinen longs for a song but Väinämöinen warns him that singing will prolong the journey home. Lemminkäinen nevertheless sings but his singing is so foul that a crane flies away in pain, flies over Pohjola and wakes the people of the Northland with its crying. Louhi wakes and checks her domain frantically and finding nothing awry she then checks the copper mountain and finds the Sampo missing. She calls to the sea-fog to cover the waters and to Iku-Turso (a sea serpent) to devour the heroes of Kalevala and return the Sampo. Finally she calls to Ukko to raise a giant storm and blow the heroes off course. Väinämöinen and the heroes are caught in the thick fog for days until Väinämöinen in desperation cleaves the sea with his magic sword releasing them from their captivity. Suddenly Iku-Turso comes toward them in great anger. Ilmarinen and Lemminkäinen are both filled with dread but Väinämöinen seizes the monster and asks him why he approaches in anger, he refuses to answer so Väinämöinen asks him again. Iku-Turso tells Väinämöinen of Louhi’s instructions and promises to leave if he is released. A short time passes and Ukko raises a great wind against the heroes causing the sea to fume with white wave and causes Väinämöinen to lose his pike harp which Väinämöinen laments heavily. Ilmarinen weeps and believes all is lost, however Väinämöinen recovers his composure and warns against weeping over the past, he commands the gods to stop the waves and calm the sea. With the work of the men and Väinämöinen's magic, the ship is repaired and saved.
