First of all, this feature will be only seen by people who want to use it and anyone beside the person using it won't see any of the emotes or hear any sounds that the user will when using toilets so chill the fuck out before worrying about preferences 'cuz I got that. You won't walk by the bathrooms and hear shitting and flushing because that would just be cruel.
Now that I got that outta the way...
Wouldn't it be nice if you had a way to reset your belly size without taking lipozene? Well now you'll have that ability. I want to code a thing where you go up to a toilet, open it, stand over it, right-click an option on it, and you get a nice gratuitous scatty noise followed by a flush sent to you to enjoy.
It will be possible to trigger if your nutriment level is high enough to make you fat. Using this will reset your nutriment level to just below that number so you stop appearing fat.
And the best part is, if you don't like scat, you don't even have to know the feature exists! Unless you spend a lot of time in bathrooms right-clicking on toilets because that's your fetish or something.
