Ariel is the main protagonist of Disney's The Little Mermaid franchise. She is the seventh and youngest daughter of King Triton, ruler of the underwater kingdom of Atlantica. The original 1989 film depicted her as a rebellious teenage mermaid princess with a hobby of collecting human objects and wished to be part of the human world against her father's rule. One night, she spotted a ship belonging to the human prince Eric who was celebrating his birthday and as she watches the celebration, she immediately fell in love with the Prince. After rescuing Eric from drowning during a thunderstorm and swam him to shore, Ariel expressed her desire to be with him. She soon made a deal with the Sea Witch Ursula who grants her three days as a human to get Eric to kiss her before the third sunset and if successful, Ariel will be human forever. If not, she would be turned back to a mermaid and be part of Ursula's Garden of polyps. All Ursula wants as payment is her voice. Unbeknownst to Ariel, the Sea Witch is actually using her as bait for Triton in order to take his kingdom. After Eric defeats Ursula, Triton (having finally realized that not all humans are bad) used his trident to make Ariel permanently human and she and the Prince soon married. She has since made numerous appearances in comic books, Disney parks, House of Mouse, video games including Kingdom Hearts, Once Upon a Time, Sofia the First, and 2018's Ralph Breaks the Internet.
To date, Ariel's only appearance in a holiday themed production was the Father's Day episode of the prequel television series "Trident True". In it, Ariel tried to find the perfect Father's Day gift for Triton and was given a map to Shark Canyon where Glow Shells were found at.
