Granted, I am from São Paulo, but it's not like I don't know stuff like Boto (which funny enough Jontron mentioned in one of Sonic 06 episodes)

And for those who don't know it; Boto is a type of pink river dolphin (pic related) and legend says that he'd transphorm at night into a beautiful dude, seduce girls, especially virgins, and get them pregnant (sometimes killed? I don't remember)

The reality of it is actually way grimier; it was a way of uncles and dad to toss around the fact that they raped their daughters/nieces. Awful, awful shit.
