Forbidden love, the serpent Mboi's fury, and the rainbow born when the two meet
The indigenous legend says the serpent-god Mboi tore the earth and created the Falls to separate Naipi and Tarobá. When they meet in the waters, a rainbow is born.

Direct answer: The legend of Iguazu Falls says the serpent-god Mboi, out of jealousy, tore the earth and created the falls to separate the young lovers Naipi and Tarobá. She became a rock at the base of the waters; he, a palm tree leaning over the abyss. Whenever the two meet, a rainbow is born.
Long ago, the indigenous peoples who lived along the Iguaçu River believed the world was ruled by Mboi, a serpent-shaped god, son of Tupã. The chief Igobi had a daughter, Naipi, so beautiful that the river's waters would stop to watch her. Because of that beauty, Naipi was to be consecrated to the god Mboi, to live only for his worship.
But among the people was a young warrior, Tarobá, who fell in love the moment he saw Naipi. On the day of the consecration feast, while the chiefs drank cauim and the warriors danced, the two fled downriver in a canoe.
When Mboi discovered the escape, he was enraged. He drove into the depths of the earth and twisted his body, opening a huge chasm that formed the Iguazu Falls. Naipi became one of the central rocks, forever lashed by the raging waters. Tarobá became a palm tree leaning at the edge of the abyss.
And they say that, whenever the two meet in the waters, a rainbow appears.
