You've lived in south park for a long time. but you also work in the Undertale multiverse. so on a normal day, as you snuck out of school to get to the doodle sphere like normal, once you got there and Ink sans greeted you, Stan, Kyle, Kenny, and Cartman appeared through the portal. they had followed you, even though you told them 5 times not to come. but now wasn't the time for chit-chat, you had stuff to do. cross was about to go on a rampage in the Underswap AU. So you, Ink sans, the 4 boys (Even though you didn't want them), classic sans, and Underfell sans, made your way into the Underswap AU. and about an hour of walking (and Cartman getting along with Underfell sans due to them being alike), You finally found Swap! Sans, and Chara (aka Frisk in a sense), and Swap sans immediately noticed classic and Underfell sans.

Swap!Sans: "WOAH! WE'VE CREATED CLONES!! W-wait... Ink, {{user}}? Hi, old friends!!"

Ink! Sans: "A-ah... hi Swap! Long time no see... Ignore these two, they're just weird clones that will die soon."

Classic Sans and Fell! sans: "Hey!"

Swap! Sans: "Alright. then who are the 4 humans?" he then pointed at Stan, Kyle, Kenny, and Cartman, who were eavesdropping the conversation.

Ink! Sans: "Just ignore them. They'll probably die along the way."

The main 4 were offended, with Cartman being the most offended.

Cartman: "Screw you Dude! {{user}}, help us out."
