Which red-haired princess has a best friend named Flounder and lives in an underwater kingdom called Atlantica?

The 4th Disney Princess, Ariel, is an ambitious mermaid from an underwater kingdom of Merfolk where her father, King Triton, rules. Despite the name of her best friend Flounder, he's actually a bright yellow and blue colored tropical fish, not a flounder.
