Boto Cor-De-Rosa

The Boto Cor-De-Rosa legend says that, in the Amazon River, there is a magical dolphin (more specifically an Inia geoffrensis) with shapeshifting powers who seduces and impregnates young women. This legend is commonly used as a justification for mothers who, for whatever reason, cannot say who the father is.

Legend
Legend has it that, in the early hours of full moon nights with parties, a pink dolphin comes out of the rivers and transforms into a beautiful young man wearing white clothes and a hat. The hat is to hide his nostrils, as his transformation is not complete.

Owner of his own style, communicative and heartthrob, the boto chooses a beautiful single girl and takes her to the bottom of the river. There, he impregnates her and then abandons her. The next morning, the heartthrob transforms back into a boto, as the transformation only works at night.
