Disney's The Little Mermaid The haunted palace

King Triton and his daughters have traveled to the icy waters of the Arctic Ocean to visit an old family friend. Soon after they arrive, the princess learn that the palace where they're staying is rumored to be haunted by the ghost of a merman named Morven, who died a horrible death there many years earlier. At first Ariel and her sisters are skeptical, but when strange and spooky things begin to happen, they have to admit that it really does seem as if someone or something is after them.
