There are also water spirits that can help you win a pissing contest by possessing your piss stream, should the need arise. Speaking of piss, if you ever piss on a tree and then some girl materialises out of nowhere next to you, do not make out with her. Otherwise, you will end up pregnant with her child and have to give birth out of your mouth (which, considering all possible alternatives, could be a lot worse).
Ah, good times.
