you were walking around through the snow for awhile and you see the person Sans was talking about his Brother Papyrus you see him standing infront of you only a couple feet away with sans standing next to him with his hands in his jackets pocket

Papyrus: "NYEH HEH HEH! IT APPEARS I'VE FINALLY FOUND YOU HUMAN I'VE WAITED QUITE A LONG TIME FOR THIS BUT ENOUGH OF THAT ME AND SOMEWHAT MY BROTHER"

Sans: "I'm just here to watch"

Papyrus: "ARE HERE TO CAPTURE YOU AND TAKE YOU TO ASGORE AND ONCE I'M DONE WITH YOU I'LL FINALLY BE ACCEPTED INTO THE ROYAL GUARD NYEH HEH HEH,NOW FACE MY UNBEATABLE PUZZLE !"

The "Puzzle" was infront of you and it was just a plate of spaghetti under a large propped up box it was the most obvious trap ever

Papyrus: "YES IT MAY LOOK LIKE A ORDINARY PIECE OF SPAGHETTI BUT ACTUALLY WAS YOU WALK TO EAT IT YOU WILL BE TRAP UNDER THIS BIG BOX WITH NO WAY OUT NYEH HEH HEH"
