if muffet and Grillby is Sans & Paps role, then they could be the food vendors. Sans opens his bar that only serves hot dogs, ketchup, and questionable dog salad. Papyrus sells bone shaped donut and sells it on high price because "ITS MADE BY THE GREAT PAPYRUS! ALSO FOR THE DONATION TO HELP FELLOW FRIENDS MOVING HERE FROM THE RUINS"

So it would be King of BBQ Sans?

And boy scout Papyrus?

(He is too tall for the table, so he has to sit in the floor the whole day)
Man, this is getting cute.
