Papyrus is not that energic like from normal Undertale, but he still likes to play and making everyone happy or just smile. He' is not doing puzzles...well...not yet.

He thinks that humans have purpose for every pain they have made.

He's about 13 years old.

(serious) That's not true! And you know it.

(happy/excited) Sans! Sans! Wake uuup! You wouldn't bealive this!

He is something between child and teen xdd.
