After the marriage with Prince Eric, Ariel heard that her father King Triton had been feeling lonely for missing her.

- Bloom, Stella, Flora, Musa, Tecna, Layla, Simba, Timon, Pumbaa, Sora, Mickey Mouse, Donald Duck, Goofy, SpongeBob SquarePants, Patrick Star, and Genie will guest star in this film.
- Even though Mickey Mouse, Donald Duck, and Goofy made live appearances with Minne Mouse, Pluto, Chip, and Dale during the real show, their roles will be extended in this film.
