 Just like the earlier parts of "Splash", Diana was naked when she came to land and became human.Unlike Madison, Diana steals the clothes from one of the surfers that advances on her.The subplot involving Earl and his mermaid wife Betty seems to be derived from the story of "The Mermaid of Gollerus" also known as "The enchanted cap", a famous Irish tale in which a man named Dick Fitzgerald finds a mermaid's red cap and marries the green-haired mermaid it belongs to.
