Asriel x Chara II The siblings II

That comedian

As we stepped out from behind the lamps we saw sans was facing towards the path. We saw huge footprints in the direction of the angry footsteps we heard. "Hey sans?" We asked. "Who was that? They didn't sound too friendly." He just shrugged and kept grinning. "Oh that's just my bro, Papyrus." He put his hood up. "You might wanna keep going in case he comes back. You wouldn't want to hear more of my amazing jokes." He winked, as we nodded, walking off in the direction of the footprints. We were walking when we reached sans talking to somebody that was taller than him, as sans turned to us, giving us away even though we knew that they would see us sooner or later. "Oh heya." Papyrus turned towards us, staring at us with dark eyes like sans, but with a little bigger pupils. "SANS..." His voice was extremely loud, like he was constantly yelling so people could hear him. "ARE THOSE HUMANS?!" Ahead of us we're some rocks, which we just stared at. "Nah. I think those are just rocks."
Papyrus looked down to the ground with sadness, but then looked back up. "WHAT'S THAT BEHIND THE ROCKS?"
"Oh, those are humans."
"OH MY GOD. I HAVE TO WORK ON MY PUZZLES!! STAY HERE  HUMANS!"
Sans shrugged, as Papyrus ran off into the other direction, away from us. Sans chuckled, facing towards us with those dark, empty eyes. "If I'm be honest, My brother ain't nothing but harmless." He tilted his head slightly down. "You hurt him, I hurt you."

We all shuddered at the thought of being hurt by sans. After all we didn't know what he was capable of. When we were done looking at each other we looked back at sans, who had disappeared suddenly.

"Woah, that's unfair. How'd he do it?" Yellow said, looking around for sans.

"Monster magic, most likely." Said Purple as they pushed up their glasses.

"Whatever! We'll find him!" Orange said, punching the air in front of them.

"The best thing to do is to continue down the trail." Dark said, practicing some dance moves with ballet shoes and tutu.

"I think we should wait until we find him to ask..." Light said, readjusting their bow.

"Maybe we should find him... But let's ask him nicely!" Green said, tying their apron and picking up their pan.

"We have to stay determined!" Frisk shouted, putting her hand in the circle they had formed. Soon, everybody had put their hand in the center. They all threw their hands in the air. "DETERMINATION!" They shouted, and a Sparkling diamond like object appeared, and they touched it. "Your file had been saved!" Rang in their head, but they couldn't see anybody say it. They shrugged and decided they continue down the path, only to see Papyrus across a patch of snow. What kind of puzzle is this?
