About The Little Mermaid: Ariel's Beginning
King Triton and his wife, Queen Athena, rule over the underwater kingdom of Atlantica, which is filled with music and laughter. They have seven young daughters, the youngest of whom is Ariel. The merfolk are shown relaxing in a lagoon above water, and Triton gives Athena a music box. Suddenly, a pirate ship approaches. Everyone escapes except Athena, who is crushed by the ship when she tries to save the music box. Devastated by Athena's death, Triton throws the music box into the ocean and bans music from the kingdom.
Ten years later, Ariel and her six older sisters live under a strict routine maintained by their governess, Marina Del Rey and her assistant, Benjamin. Marina hates being the girls' governess and longs to be Triton's attaché, a job currently filled by Sebastian the crab. Ariel is frustrated by their current lifestyle, which brings her into conflict with her father. One day, Ariel encounters Flounder, a young fish whom she later follows to an underground music club. She is overjoyed by the presence of music, and is shocked when she sees Sebastian performing there. When her presence is revealed, the entire band stops playing and hides, believing Ariel will tell her father about them. Ariel sings a song explaining her love of music and the remembrance of her mother and she joins the club with an oath.
