Behold, at one time many fish began to be lacking, so as not to be necessary the Indians made a deal with the giant snake, M’boi: each year one of the most beautiful Indians would be given to him as a payment for him to always give fish. and freshwater to the indigenous. M’boi accepted the offer, and it was a pride for the natives to be chosen to be the gift of the God of the waters.

Preparations for the delivery party began, they were all happy and the chief very proud of M’boi’s choice.
However the warrior Tarobá was enchanted by Naipi, and from there born a great love. They both knew it would be forbidden love because if M’boi found out all the agreement and respect for the ancestors would be broken, but they left everything behind for that very night to escape together.
When the day of the big party came, the village was adorned, prepared very “kaguiju” – typical fermented drink. Everyone drank a lot and at that moment Tarobá and Naipi saw the opportunity to escape. They took a small canoe and rowed down the river.
The movement of the waters awoke M’boi that realizing that his betrothed was running away with another man was seized by rage swam towards the two, who were almost to the Paraná River, where the water god was not allowed to go.
With fury, he lifted his huge body and dived violently downstream. Then a huge gap was opened where the fugitives disappear and the waters formed the Iguazu Falls.
