Ariel was born as the seventh and youngest daughter of King Triton and Queen Athena in Atlantica. Her mother died when she was very young, and she grew up usually on her own, under the care of Sebastian, her father's adviser. Ariel became very adventurous and with the hobby of exploring and collecting things, even going so far to get unusual items that she ventures to forbidden and dangerous places, even endangering herself. Travelling all over the sea with her friend, Flounder, she learns about the existence of humans, and develops an infatuation with them. She begins to collect human knick-knacks and eventually even creates a secret cave to hide them all in, because she has so many. Her passion for humans becomes so strong that she even begins to fantasize about becoming one. Her daydreams about humans begins to interfere with her duties as a princess, making her father suspicious. Her father sends Sebastian to follow her and keep her out of trouble. Sebastian discovers Ariel's cave of items, and is shocked. But he cannot stop Ariel when she discovers a ship sailing over her. She spies on the men on the ship and immediately falls in love with a dreamy, young prince named Eric at first sight. A fire begins on the ship, and Eric falls overboard and is almost killed. Ariel saves him and brings him to shore. He is unconscious and she sings to him until he awakens. He hears her beautiful singing voice as he awakens but Ariel vanishes as he wakes up. He falls in love with her too and seeks to find her again. In the mean time, a statue of him fell into the water, which Ariel finds and collects. Sebastian informs Triton of Ariel's collection and contact with humans and the danger of it. In an angry way of protecting her, Triton goes to her cave, where she was swooning over her Eric statue. Ariel accidentally says how she loves him, angering Triton further and he violently destroyed all of her collection, in a failed attempt to keep her away from humans. This infuriates Ariel and she swims away from home. Ursula, a sea-witch who holds a grudge against Triton, spies on Ariel and thinks of a plan to use Ariel and get Triton's triton. Because Ariel was furious with her father, and distraught that all of her knick-knacks were destroyed, Ursula sends her pet eals to bring Ariel to her lair for a chance to become human and win Eric's heart. Ariel almost immediately agrees. At Ursula's lair, Ariel signs a contract that she gets to become human for 3 days, in which the time she must get Eric to fall in love with her and kiss her. In exchange for this, Ursula wants Ariel's voice. If Ariel succeeds in making Eric fall in love with her, then she gets to remain human. If she doesn't, then she becomes a mermaid again. Ariel agrees leaving her mute and is turned human and sent to the shore. Ariel is found by Eric's dog, Max and brought back to the castle. Ariel manages to spend lots of time with Eric, and manages to speak to him with her hands. She almost gets him to kiss her but is interrupted by Ursula's eels who are trying to wreck her chances to win Eric. Ursula then disguises herself as a beautiful young woman named Vanessa using Ariel's voice and casts a spell on Eric, and tries to marry him. On the ship though, with the help of Flounder and Scuttle, Ariel manages to break the locket on Ursula containing Ariel's voice. Ariel's voice is returned to her, and Eric's spell is broken. He realized that Ariel was the girl who sang to him on the beach. However, before they can kiss each other, the sun sets and Ariel returns to her original form. Ursula also transforms into her former self and takes Ariel down into the sea, where she is confronted by Triton. Ursula makes a deal with Triton that she will free Ariel if he gives her the trident. Triton agrees and he is turned into a sea polyp. Angered, Ariel angrily attacks, strangles, and yanks Ursula but is immediately subdued and thrown into a wall. As Ursula threatens her with the trident, Eric angrily throws a harpoon at Ursula's right arm very hard. Ursula tries to shoot him with the trident, but Ariel yanks her hair and she accidentally destroys Flotsam and Jetsam. Enraged, Ursula transforms into a giant version of herself and nearly destroys Ariel with the trident, but is impaled & destroyed by the bow of a ship driven by Eric. Ursula dies from her injuries, and Triton and the other mermaids who were turned into polyps are returned to their normal forms. However, Ariel is sad that she can't see Eric again now that she has returned to a mermaid. Fortunately for her, Triton transforms her into a human again, allowing her to be with Eric. Soon after, the two are married as the mermaids and humans celebrate.
