Indonesian film Duyung Ajaib (The Magical Mermaid) is a lighthearted comedy where Otong, a struggling sailor, unintentionally encounters a mermaid (Ijah Bomber) while at sea. As per the merfolks' tradition, Otong is to be married to the mermaid who looks, shall we say, like a homely elderly aunt.
Otong brings the mermaid back home and keeps her in a pond. Through the machinations of some local magic, Otong casts a sort-of spell that transforms the mermaid into a beautiful young woman with legs (Nenny Triana), and the pair have a lovey-dovey marriage. At least, until Otong unintentionally breaks one of the conditions of the spell and the mermaid sees the ocean again, which makes her long to return home, which she does.
