just a concept for now, but i could (or someone could) turn this into a mod. lore: it's sprunki but everything is bland and dull. nobody has any fun. they're just...there. the color had been sucked out of them, eliminating their personalities too. only jevin is unaffected, and he has to try and save them.
more info: gray, durple, and simon are the killers of horror mode. the reason jevin is unaffected is because he wasn't there at the time when the "infection" came around. black isn't in this mod. they're basically just like walking zombies and the only word you'll usually hear from them is "meh."
