~ Flotsam and Jetsam, Ursula's pets.

Flotsam and Jetsam were a duo of moray eels and the secondary villains from Disney's The Little Mermaid. They were the loyal minions of Ursula the Sea Witch. Contrary of the fact that Disney henchmen in some films are depicted as incompotent and abused, Flotsam and Jetsam are very competent in their work for Ursula, who treats them lovingly as pets, despite ordering them so much. They were ordered by Ursula to persuade miserable and desperate merpeople to visit the Sea Witch and ask her to help them for a price.

When Ursula learned of the disobedient princess of the merpeople kingdom, Ariel, she sent Flotsam and Jetsam to watch over Ariel as she became more desperate to become a human. When Ariel's father, King Triton, destroyed her collection of human items, including a statue of the human prince Eric, Flotsam and Jetsam arrived to talk to her. At first, Ariel did not trust the eels, but when Flotsam and Jetsam reminded the princess of her love for Eric, she accepted their invitation to Ursula's home in the belly of a deceased Leviathan. Ursula was able to turn Ariel into a human, at the cost of her voice. The deal was that if Ariel could get Eric to kiss her within 3 days, she could remain human forever. If she couldn't, she'd turn back into a mermaid and by bound to Ursula forever. When Ariel's friends, Sebastian and Flounder, attempted to stop her, Flotsam and Jetsam wrapped themselves around them to keep them quiet. However, they let them go after Ariel is finally turned into a human, allowing both Sebastian and Flounder to take her up to the surface.

After Ariel had become human with some of Ursula's dark magic, the now-human princess met Prince Eric in person, and they fell in love. While the two were in a swamp, they attempted to kiss. Ursula, attempting to keep the two from kissing, sent Flotsam and Jetsam to sabotage the couple's time together by tipping their boat. They succeed in doing do, to which Ursula praises for.

Durring the climax of the film, Flotsam and Jetsam attempted to kill Prince Eric by dragging him underwater. When Ursula attempted to kill Eric by shooting him with Triton's magic trident, Ariel pulled the Sea Witch's hair back, causing her to kill the eel duo by accident instead. Before they died, both Flotsam and Jetsam are known to succeed in the tasks Ursula has given to them, and because of that, Ursula is completely shocked that she killed her eels by accident, and mourns for them out of remorse before turning her rage on Eric and Ariel.
