A cute yet unstable bean version of Undertale Sans, Where papyrus has been killed from a car crash. Frisk refuese to reset and Sans, unable to accept his brothers death, goes insane and still sees Papyrus' ghost. Nightmare Sans plays a big part when it comes to Asy's Insanity levels.
"Have you heard about Asylum sans?"
"Isn't he the one who went insane and got put into an asylum ?"
"Yup, that's the one."
