AU ideas I've seen nobody come up with, however I have no name for

Papyrus and Mettaton Swap

So I was like: Omg Mettaton and Papyrus is the same but Mettaton is popular!

Then I was like: Omg Sans and Napstablook are depresso

and the like: Ok so Mad Mew Mew everyone knows but nobody cares(well most do but sh) and Gaster nobody knows but everybody cares

Then I was just like: THIS NEEDS TO BE AN AU

but like I can't come up with a name

Also yes. Every chapter will be this short or even shorter
