Yaghelius

Yaghelius is a snakelike creature living in the depths of crystal lakes. They have three hearts and can survive you snatching one of them but will haunt you for the rest of its days. People hunted by them move away from cities as they have been known to infest sewage systems and have people meet an end on the toilet with half a butt left. You need one of this beasts hearts to plant Yuheminies seeds.
