If there was a wink animation, maybe if the character leaned their head or moved their neck slightly forward as the blinked, it would be more obvious they did so.
Not sure how a "pee" animation would be useful in the game though. Either I'm completely missing the point here or eet was just added to the list for funsies?
Not because I rp that much, but how many actually pee in their roleplays? If you mean marking territory it would probably look different. I just think that if it was put in the game, it would be used in a bad or wrong way. It's not something that would be good for the game exactly.
Nothing against the other ideas though.
