I'm TELLIN yall Deltarune is a prequel and Sans can travel universes. This might be a bit far fetched but I have a theory that Deltarune is and isn't a prequel of Undertale. HEAR ME OUT. So, we know that Sans' door and the door in the Dark World have the same kind of lighting. It could be that Sans originated from Deltarune, we know he's super smart and connected to gaster, and one day he found a way to travel to different places and/or dimensions, now keep in mind in Deltarune, Papyrus MIGHT be of Kris' age, because at the end of Chapter 1, Sans asks Kris to come over sometime to play and hang out with Papyrus. So, I think that sometime after Susie gave Sans the drawing, he travelled to UNDERTALE, where he continued to live with his brother Papyrus, and he put Susie's drawing in the drawers with a note, saying "Dont forget," which is probably a reminder to Sans to not forget about Susie and the others, OR about the dimension travel overall. And we know that the residents of Snowdin said that the Skeleton brothers showed up randomly one day, so it could be that they came from Deltarune, making Deltarune a parallel universe from Undertale, but also a prequel to it. That's my theory.
