Flotsam and Jetsam

Flotsam and Jetsam are two moray eels who serve Ursula, the sea witch. They first appeared in Disney's The Little Mermaid, and have appeared in all Kingdom Hearts games. They are two of Disney's most famous evil lackeys. They were both voiced by the late Paddi Edwards in the movie and by Corey Burton in the games.

Description
Not much is known about the two eels, only that they have served Ursula for some time. They serve as both pets (or children) and minions to Ursula, and they are usually used as spies in her evil plans. Like an evil twin symbol, they each have one glowing yellow eye (Jetsam's on the right, Flotsam's on the left) that they use to see things others can't. The true powers our origin of their eyes is unknown, but, as seen in a scene in The Little Mermaid, they may be used as viewing portals by Ursula, meaning she can see what they see.

The Little Mermaid
In the film, Ursula uses Flotsam and Jetsam to manipulate Ariel into visiting Ursula. They use their sly and cunning ways to convince her into thinking she will live forever with her love, Prince Eric. They are both killed when one of Ursula's wayward shots of the King Triton's trident hit the pair of eels.

Kingdom Hearts
The two play a similar role in the game as the movie. They taunt Ariel into thinking that Ursula will let her venture to other worlds if she trades the trident for her dream to come reality. Ursula sends Flotsam and Jetsam off to search Triton's palace for the keyhole, but they are unable to find it. They later fight Sora and co. in Ursula's grotto. After the fight, they curl up and die in a mist of ink.

In the Kingdom Hearts II, Flotsam and Jetsam have been reborn. They only briefly appear in the song-battle 'Ursula's Revenge'. During the song, the eels are defeated by Sora, Donald and Goofy.
