King Triton, and the other residents from Atlantica are very happy to know that their hero Apollo is returning home. 20 years ago during the Sargasso War, Atlantica was in a battle between the octopans who contained a trident that was more magically powerful than King Triton's trident. Apollo, in the vines, snuck up on them and broke it.
After the story, Apollo appears. He, Ariel, and Flounder go on an adventure to Valhalla, the land of the heroes. Going through several dangerous obstacles, Ariel noticed that he did not speak much, and was inclined to give up. Ariel is courageous and curious, and persuades him to continue. When they got there, with Ursula watching them on the crystal ball, they are captured by the Mervikings, and Apollo tells Ariel that his victory for the Atlanticans was an accident. They only left after the Vikings discovered that he was the Apollo, and the condition was if he defeated the Sea Dragon. Ursula revives the octopans and gives them eight magic tridents; but Apollo defeats them with his new dragon. Afterwards, Apollo is congratulated for being a real hero.
- The Sea Dragon has a similar appearance to Maleficent's dragon form.
