Drownix burrow underground and dig under the houses of people to consume their dreams while they're sleeping. The rocks on the end of their tail rotate clockwise whenever they consume a dream and counterclockwise when they consume a nightmare.
There is a magnet in its brain that prevents an Drownix from losing direction while tunneling. If your nose becomes itchy while you are sleeping, it's a sure sign that a Drownix is standing above your pillow and trying to eat your dream through your nostrils.
