Enter a world where the ocean floor is full of fish and Ariel longs to stroll and dance with humans. Sing along with colorful puppets, spirited live performers, wondrous special effects and enchanting film clips. Sebastian the crab and his hot crustacean band make a splash with “Under the Sea.” Ariel yearns to trade her tail for legs in “Part of Your World.” When Ursula the Sea Witch grants her wish, Ariel gets more than she bargained for—before discovering her own happily-ever-after at the grand fin-ale.
