@Underfellx I liked the lore of Alphys making everyone's outfits which included giving everyone those same red boots lmfao. I imagine she still has them in a closet somewhere and didn't have the heart to return them.

There is no correct way to Underfell, AUs are so cool because it’s just your own version. If it’s super edgy thats awesome. If it’s super goofy that’s awesome. Life’s a party, enjoy it !

UF doesn’t have a Gen,pacifist , or neutral route. It’s called Betrayal, Closure , and Trust route. Frisk doesn’t kill in this AU. the player still exists, but every time the player tries to land a blow I’d imagine it’d say something like “ They don’t want to do that”

@Ish_bruhh HELLO I made the AU, I can safely say that @bonezonejpg ‘s UF document wraps up what the unanimous canon version is of the AU. Otherwise UF at its core is a design based AU made up of edgy monsters, anyone can write their own version for.

OK FELL'Y ODD PARENTS!!!!! UF Peri, He lets the whole being a famous,young, and powerful fairy get to his head. Becomes a fairy actor and commits to being a famous celebrity. Confident, obnoxious, and gaudy. Only uses the voice he was first introduced with.
