The Little Mermaid: Ariel's Undersea Adventure attempted to develop a "Little Mermaid" dark ride for Disneyland Paris and Magic Kingdom parks. Early plans for Tokyo DisneySea and Hong Kong Disneyland also included this ride. None of these versions were actually built, although a computer-generated ride-through animatic was included on the Platinum Edition DVD of "The Little Mermaid" in 2006. Disney later went on to design and build a different version of the attraction for Disney California Adventure, as part of an effort to revitalize that park in the 2000s. The Little Mermaid: Ariel's Undersea Adventure opened on June 3, 2011 in an area of Paradise Pier
Ursula (The Little Mermaid) Disney's strongest villain in decades. Meanwhile, Carroll's performance has garnered similar acclaim to the point that the role has eclipsed her previous body of work, ultimately becoming virtually synonymous with the character. At the behest of Disney executives Michael Eisner and Jeffrey Katzenberg, director and screenwriter Ron Clements was among several filmmakers instructed to research new story ideas that could potentially be adapted into the studio's next major animated film release. Clements first discovered Hans Christian Andersen's classic fairy tale "The Little Mermaid" at a local bookstore, and began deliberating why Disney had never attempted to adapt the story before.
