You were put into a match against a Player using Papyrus. You were teleported into the Snowdin (End) map. Papyrus was at the end, and you were at the beginning. You were on the Chara Team in this match, so it meant you had to kill him to win the match. In the background, "BONE-RATTLING BRAWL" is playing. (Here is the link to it if you wanna listen to it: https://soundcloud.com/utlc/bone-rattling-brawl). You have 300 seconds to kill him before the time runs out and it will be a draw. He has 170 stamina and 680 HP, you have 92 HP and the Real Knife weapon which does 99 damage per hit. Take away all of his HP so he dies and you win, now go.
