[Initially, the screen is black, and we hear someone knock on a door.]
Papyrus: SANS, WHAT IS THAT INFERNAL KNOCKING SOUND?!
[The light goes on, revealing the scene to be in Papyrus and Sans' house, as Sans walks through the door. The song "sans." begins playing as we see the following exchange.]
Sans: relax bro, it was just the mail.
Papyrus: IS THERE ANYTHING FOR ME, THE GREAT PAPYRUS?
Papyrus: THEN WHAT'S THAT LETTER FOR, MR POPULAR?
Sans: it's a letter from some guy named "siivagunner"...
he invited me to some tournament.
says i get the chance to be a king or something.
Papyrus: THAT SOUNDS SPECTACULAR!!
BUT WHY WOULD THEY INVITE YOU. . .
TO AN EVENT OF SUCH CALIBER??
Sans: dunno. i'm a lovable guy.
Papyrus: THAT IS HIGHLY DEBATABLE.
[Papyrus begins to pout.]
Papyrus: THIS TOURNAMENT WOULD HAVE BEEN MY DREAM COME TRUE.
MY CHANCE TO BECOME BELOVED BY ALL!
BUT INSTEAD THEY WENT WITH MY LAZY, GOOD FOR NOTHING
[Sans cuts his brother off as the music abruptly stops.]
Sans: i'm not gonna go.
Sans: i don't wanna be a king. too much work.
Papyrus: BUT YOU HAVE A PERFECTLY GOOD INVITATION
AN OPPORTUNITY THAT OTHERS WOULD KILL FOR
AND YOU'RE JUST GOING TO PASS IT UP??
HOW UTTERLY SELFISH OF YOU, BROTHER!
Sans: you can have it if you want.
Papyrus: YOU'RE NOT KIDDING ME THIS TIME?
["Bonetrousle" begins playing as Papyrus starts gleefully spinning in place.]
Papyrus: NYEH HEH HEH HEH HEH HEH HEH HEH HEH HEH HEH HEH
[Papyrus explodes to a stop.]
A CHANCE TO SHOW THE WORLD. . .
WHAT THE GREAT PAPYRUS CAN DO!
THIS WILL SURELY MAKE ME POPULAR. . .
BEYOND MY WILDEST DREAMS!
A DAY ALL ABOUT ME!
Papyrus: I SO DESERVE THIS!
Sans: yep. congrats bro.

Papyrus: HOW TYPICAL OF YOU.
ALWAYS MAKING MY SPECIAL MOMENTS ABOUT YOURSELF.
BUT IF YOU INSIST.
Sans: bear with me bro, it'll be so...
...bonely without you around.
[A rimshot plays as the camera zooms in on Sans facing the viewer, just like in Undertale.]
Papyrus: . . .
I AM TOO EXCITED TO BE ANGRY ABOUT THAT PUN RIGHT NOW.
LOOK OUT SIIVAGUNNER, YOUR FUTURE KING IS HERE!
[Sans faces the viewer again and shrugs.]
