Also, I don't know if that is a thing already or not, but an AU where Frisk is looking for the bathroom, because you know, after a while they really have to go, and the ocassional scary stuff doesn't help either.

I can totally imagine Frisk asking for directions which Whimsalot interprets as prayer, and Final Froggit as something mysterious. Then there's the chance of pleading Undyne, asking Alphys about using what is marked to be a bathroom, but is in fact the True Lab, and following Papyrus when he excuses himself by going to the bathroom.

There are even more, but I think you get the feeling.
