A human explorer known in the episode as the author of The Little Mermaid story, Hans Christian Andersen, boards a primitive submarine to explore the undersea realm, and crosses paths with Ariel when his submarine is damaged and starts to leak.
- Ariel's implied role in the creation of the original story (published in 1837) in this episode strongly implies that the franchise takes place during the early-to-mid-19th century. The original tale was first published in 1837, so it is likely that the franchise took place around that time.
- Ariel's pose in the final scene is a reference to The Little Mermaid Statue in Copenhagen, Denmark.
