Ariel (voiced by Jodi Benson), is a free-spirited mermaid, who is off on the adventure of a lifetime with her best friend, the adorable Flounder (voiced by Jason Marin), and the reggae-singing Caribbean crab Sebastian (voiced by Samuel E. Wright) at her side. But it will take all of her courage and determination to make her dreams come true-and save her father's beloved kingdom from the sneaky sea witch Ursula (voiced by Pat Carroll).
