Flounder is the secondary tritagonist from The Little Mermaid. He is Ariel's best friend and despite his name, he is not a flounder, he is a tropical fish.
He was voiced by Jason Marin in the 1989 film, both Edan Gross and Bradley Pierce in the television series, Parker Goris in the prequel and Kingdom Hearts II, and Cam Clarke, as an adult in the sequel.
Personality
Flounder scares easily, and is prone to panicking under stressful situations, but when Ariel is in trouble, he comes through for her without hesitation. As seen in Ariel's Beginning, Flounder was not always jittery and nervous, in fact, Flounder was just as adventurous as Ariel. However, it can be concluded that after the first few adventures with Ariel, Flounder began to suffer from anxiety.
As mentioned above, despite his fear, Flounder will eventually come through for Ariel when needed, to the point where he's not only her closest friend, but her most loyal one, at that. Because of this, the two are nearly inseparable, and the bond is incredibly strong throughout the franchise, especially during episodes within the television series. Like Sebastian, though, even Flounder, at times, tires of Ariel's reckless behavior and expresses so when a dangerous adventure is at hand, but he willingly puts up with it not only to watch out for her, but because he truly loves her, much to Ariel's relief and joy. Because of this, Ariel is rather protective of Flounder, and when in peril, she always puts his safety before her own, making her he's always the first to make it out safe, once again showing the connection between the two to be powerful, to say the least.
Appearances
The Little Mermaid
In the film, he is the only character to give unconditional support for Ariel's fascination with human things, and at one point gives Ariel a statue of Eric as a gift. He is first seen after the performance, Daughters of Triton with Ariel after sneaking away. When Ariel confesses she is in love with Eric, she strikes a deal with an evil sea witch. Flounder joins Ariel in Eric's Kingdom as she tries to win his heart.
Because he can't survive above water, he is forced to only be able to get news from Scuttle or Sebastien nearby water. He was persistent in asking if they were kissing, showing how dearly he wanted Ariel to get her happy ending and how supportive he was.
Flounder joins Sebastian, Scuttle and other fish in the song Kiss the Girl. Later, Flounder helps Ariel defeat Ursula who is planning to capture Ariel by battling Flotsam and Jetsam. When Ursula is killed, Flounder attends the wedding and gets a big good-bye kiss from Ariel as she and Eric enjoy their marriage. He is voiced by Jason Marin in the 1989 film and the album called Sebastian From The Little Mermaid.
The Little Mermaid: The Series
Flounder appears in all the episodes of the prequel television series, sharing constant adventures with Ariel. In the series, he is voiced by Edan Gross and Bradley Pierce. He generally tries to serve as a voice of reason in comparison to Ariel's more adventurous nature, but usually goes along with her anyway. He is often seen giving rides to Sebastian, who cannot swim as fast as Flounder or Ariel. According to the television series, Flounder's real name is Guppy Number 35. In the episode "Land of the Dinosaurs", when he has been found frozen in an ice cube, Ariel thaws him with King Triton's trident and he gets a cold resulting in his sneezing.
The episode "The Evil Manta" shows that Flounder and Ariel met as young children, though Flounder initially mistook Ariel for a large fish that intended to eat him. The same episode shows Flounder outsmarting Evil Manta, who had been trying to spread prejudice throughout Atlantica. Flounder simply fakes believing Manta's words then works with Ariel to fix the problems Manta caused. The episode "The Beast Within" has Flounder being bitten by a dangerous Howling Hairfish; he then begins to transform into one himself. However, Ariel is able to cure him with the assistance of silverfish.
The Little Mermaid II: Return to the Sea
Flounder has a small role in The Little Mermaid II: Return to the Sea, where he is voiced by Cam Clarke. He is first seen at the celebration of Melody's birth and isn't happy about Ariel's decision to keep Melody away from the sea and insists she should explain everything to Melody, which she doesn't. He is later seen 12 years later where he is reunited with Ariel and takes part in the search for Melody. He is shown as an adult and became a father himself, having five children of his own. He is also shown as braver than he was in the first movie.
As the search continues, Flounder and Ariel spot the two stingray pets of Morgana (the antagonist of the film) in the grounds of the palace. The duo follow them to the sea witch's lair, where they believe Melody is being held captive. Whilst Scuttle heads off to warn Eric, Flounder and Ariel enter the icy fortress, only to find themselves captured, along with Melody. Whilst Ariel falls under a hostage situation at the hands of Morgana, Flounder is imprisoned alongside Melody, only to be freed by the princess' companions, Tip and Dash. After a battle ensues and Morgana meets her defeat, however, peace is restored and both the land and sea are free to coincide in harmony as they did years before.
The Little Mermaid III: Ariel's Beginning
He has a larger role in The Little Mermaid: Ariel's Beginning, in which he first meets Ariel (contradicting the TV series) and later unknowingly leads her to the Catfish Club, where he works as a waiter, but dreams of being a part of the the Catfish Club Band. His characterization is notably different in this movie; he doesn't scare as easily and is much more carefree and high-spirited. It is possible that he became more worrisome after the first few adventures with Ariel. He's obsessed with music, constantly humming and beatboxing even at inappropriate moments, which, given that music is forbidden in Atlantica, lands him into trouble on more than one occasion, but which also helps others keep their spirits up, most notably when his beatboxing kicks off the reprise of "Jump In The Line (Shake, Senora)" when he, Ariel, Sebastian and the Catfish Club Band are on the run from Atlantica. In this film, he is voiced by Parker Goris.
