Here's some Info about Him:

Everyone calls him Paps instead of Papyrus

He doesn't smoke unlike normal Swap Papyrus.

His favorite condiment is mustard.

He owes Muffet (who is swapped with Grillby if you didn't know) 461 dollars worth of mustard and soda.

He and Asgore tell each other knock knock jokes every week.

He tends to say Nyeh heh heh rather than laughing.

He has 3 Attack but cannot take away invincibility frames.

He has 20 Defense and 680 health but Chara still one-shots him.

He uses a broken bone to block attacks rather than dodging them.
