In this story the god Rama enlisted Hanuman to help rescue his wife, Sita, from the demon Ravana, king of the island nation of Lanka. In order to reach the island, Hanuman instructed his monkey warriors to construct a bridge from the mainland with stones. But as they dropped their stones they would vanish. It became apparent that these stones were disappearing because fishes, guided by the mermaid Sovann Macha, removed them.
