Our beloved Monsters live at the surface for almost a year now. As Christmas time begins, they are all overwhelmed by the festivity and happiness this time of the year brings to everyone. And monsters realize: it's been a long time since they celebrated a family festival under the stars. This is basically a small collection of one-shots that play in the same universe. It will work like an Advent calendar, which means there will (hopefully) be one chapter per day , until it's Christmas eve. Please understand that I am not a native English speaker, so if you find any grammatical errors or typos just point them out to me. I will gladly correct them and learn for the future.

THIRD TIME IS THE CHARM! [Highest ranking #98 in fanfic] NO IMAGES R MINE

Sans x Reader One-Shot Booklet by ZanaBSparrows

This is just a collection of Undertale-themed one-shots that go along with the plot of my Sans x Reader fanfic, "When Two Souls Meet." It's a community project, and will have several entries from the winners of my one-shot contest, as well as some chapters written by yours truly. This can be read as a stand-alone group of one-shots, or connected directly to WTSM, as it is technically a direct continuation.

Life in a forest ( Au sanses x reader x au papyruses ) by Tr33Hollows

An au sanses x MONSTER reader x au papyruses? Papyri? A fanfiction, it is not self-indulgent. So if your just lookin for some fanfiction to put yourself in, here it is. :)

Art cover and other art isn't mine! I'll be doing oneshots. I'll do anything but r@pe, !nc3st, and things related. Note: AFTER "THE RUNAWAY", THERE WILL BE NO MORE FEMALE BLUE. EXTRA NOTE: If you ever come on here just to ask why I won't make female Blue, you're getting blocked. I have my reasons for my decisions, and I refuse to change his gender. Also, please no longer ask for part 2's. It's called a ONE shot book for a reason 🥀. #1 in Bluemare on 9/10/25 #4 in Nightberry on 9/20/25 #5 in Sanscest on 9/18/25 #6 in Underswap on 7/12/25 #8 in Bluemoon on 9/10/25 #9 in Dreamtale on 8/28/25 #11 in Nightmare on 9/10/25

"What is happening?" I asked. Sans looked at me and I could tell he had an answer but he wouldn't tell me. "look, Leah-" "What is happening..?" I asked again.
