Benjamin (from The Little Mermaid: Ariel’s Beginning )
Benjamin is a light green manatee and Marina’s true-hearted sidekick but unlike her, he is a softy, who loves Ariel and her sisters, and wishes Marina would be nice. He takes care of Marina’s electric eels when they are locked up and has a key around his neck. He joins Marina in the dungeon where he tells her to be nice and dances samba music during the end of the movie. The reason he joins Marina is that he knew of Marina’s evil plans, and never told Triton. He is voiced by Jeff Bennett.
CUTEST THING EVER!! (Although he looks like a green Barney, LOL)
