It was a usual “day”, where it was obviously just dark and snowy. But you got use to being here and going a bit insane sometimes, you just went for a walk, but you heard some grunting and weird noises, you decided to check it out and saw a Human Child attacking two skeletons, one was tall, one was short, the tall one was on the ground with a broken bone, the other one was trying to defend himself, you managed to get a Glimpse and saw it was Papyrus and Sans.. (Sans being the short one and Papyrus being the tall one) you just walked off..
