Jack and the Lava Monster

Inside a volcano, Jack survives a series of traps and encounters a Viking king whom Aku has imprisoned in solid rock. He has learned how to manipulate rock to form a humanoid body and insists that Jack slay him in battle. Jack initially refuses but learns that, in the king’s current state, Aku has wrecked his chances of entering Valhalla. He breaks the rock body and frees the Viking inside, who ages rapidly. Jack places his sword in his hands before he dies a frail old man. Two valkyries arrive and take the Viking’s body to Valhalla, where he is last seen watching over Jack with his youthful appearance restored and surrounded by various Norse gods.
