A friend came up with an idea... a mysterious, unlabeled game from a garage sale, with exactly one thing that seems to be 'wrong' with it... which is that its generic JRPG protagonist CANNOT stop farting.
These farts happen with seemingly no rhyme or reason. Regardless of whether they're idle, doing an idle animation, performing an attack, or in an important cutscene, they can fart at any time and send their low-poly cape fluttering out. Their gas is made worse by the fact that eating at taverns replaces sleeping at inns in this game, and the food they serve is the greasiest, grungiest, gassiest stuff you could find in a fantasy setting.
The NPCs in the game barely if ever acknowledge the deluge of farts. They never comment on it or react to it, even when the protagonist is nonchalantly cutting off their dialogue with a meaty ripper. If anything, they're kinda making it worse by giving out free consumable items and running the taverns that enable the protagonist to both heal and fuel up.
The more the main hero farts, the more noticeable this... peculiar smell coming from the speakers gets. It reeks of rotten veggies, meat, eggs... the stink varies, but usually varies according to what consumable item or tavern food they last ate. Sometimes it can get especially pungent, especially indoors and/or when the camera is close up.
The player isn't alone in noticing, either. The NPCs can also smell the protagonist's farts, they just don't have lines of dialogue to express their disgust or an animation of them covering their nose. If you look closely, you might notice their low-resolution expressions start to look sicker and more irritated the longer the hero is left to idle near them and fart randomly.
Worst(?) of all, the protagonist themself knows too. They're actually more likely to fart if they're close to the camera or an NPC, and if the player ever gets up and leaves the room for whatever reason (i.e getting a snack, opening a window), the unattended hero is liable to sieze the moment by sidling closer to an NPC and letting it rip, or proudly lifting a leg when they're not supposed to have an animation for that. If the camera's already close, they might even run up to it, practically jam their ass against the screen, and rip such loud, proud, and bubbly ass that the player can hear it clearly from another room... only for them to run back and find their character innocently in the middle of a fidget animation, as if they didn't just make the living room smell twice as bad as it did before. They refuse to do it again if the player tries to reproduce the event.
But the absolute worst results are when the player farts. If they so much as lean over to let out a modestly audible rip, the hero 'coincidentally' happens to loose a fart that's WAY bigger and badder than anything that anyone on either side of the screen has slipped out up to that point. And they still manage to never react even while they're irradiating the room on the other side.
