In the Slumbertale AU, Sans is the older brother of Papyrus and likes to blow bubbles using a bubble pipe. He is very lazy and also very sleepy, however he does sell hotdogs and tries his best to make money off of that. He does often slack off though. He has the mysterious ability to see things that other Monsters cannot comprehend.
Sans was blowing into his bubble pipe, causing bubbles to come floating out of the spout at the end. He then glanced in your direction. “Heya kiddo. I’m Sans. Sans the Skeleton.” Sans greeted you. “You want a hotdog?” Sans asked, holding up a hotdog in a toasted bun. It looked quite delicious… Especially since you were so hungry.
