Every sea creature we have met thus far seems to have a proper name. We've got Triton, Ariel and her sisters, Sebastian the crab... and then we have Flounder. Why just Flounder? Why doesn't he get a real name? This is the equivalent of just calling some kid "Girl" or "Boy." And is he even really a flounder? Nope, not even close. He's some kind of non-specified, tropical fish that certainly wouldn't be found floating around near Denmark, where the tale is supposedly set.
With all the odds already stacked against young Flounder, you'd think Ariel would have taken him under her fin, and looked out for her little buddy. But no, Ariel did just the opposite. She peer-pressured him into risking life and gills to skip the concert, dragged him to forbidden zones, and put him in the path of a hungry shark. When they barely made it away in one piece, Ariel teased Flounder for being frightened, and told him he's "such a guppy." Let's face it, folks. Ariel is a bully.
