Ariel and her husband, Prince Eric, have a little problem with their daughter, Melody, in the sequel to Disney's landmark The Little Mermaid. Melody is threatened by Morgana, the evil sister of the sea witch Ursula (both voiced by Pat Carroll). Before you can say "Briar Rose," Melody's parents decide to keep their daughter's roots a secret, forbidding her to learn about the ocean while Morgana is around. Now the budding teenager secretly frolics in the sea with Ariel's old friends, Sebastian and Scuttle. When she learns the truth from Morgana, Melody becomes an unknowing pawn in her scheme--and Mom has to take to the sea again to help.
