so in Ponytale, there are these two girls named Asphalt and nightlight who are insane cosplayers of Sans and Papyrus, they refer to each other as Sans and Papyrus and act like the skeletal brothers 24/7, even at home when no one can see them. Nightlight even drinks ketchup like Sans does, no one know’s they’re real names due to them never telling ANYONE. so as of now you and I are the only ones who know that “Papyrus” is Asphalt, and “Sans” is Nightlight.
