Thank you for your comment, I'm so so glad you like the game!! :)
As for those sprites, you can't trigger them in the game, sorry. I drew them mostly for fun because I'm really into piss but I did have an idea for a "piss mode" you could turn on but I didn't end up doing that. But they do all exist in the files, so you can look at them as much as you want to. 😉
