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
The Little Mermaid year apart. When a mermaid turns fifteen, she is permitted to swim to the surface for the first time to glimpse the world above, and when the sisters become old enough, each of them visits the upper world one at a time every year. As each returns, the Little Mermaid listens longingly to their various descriptions of the world inhabited by human beings. When the Little Mermaid's turn comes, she rises up to the surface, watches a birthday celebration being held on a ship in honor of a handsome prince, and falls in love with him from a safe distance.
