    Sans might be free from Error, but that certainly doesn't mean he's happy. Post-Errortale, Swap!Sans escapes from Error and his timeline goes back to normal, but now Sans has to live with the lifelong trauma Error gave him and readjust himself back into society. It's going to be very hard, especially since he appears to be the only one who remembers the incident. Errortale is by loverofpiggies. Just a one-shot, sorry! I might continue it. Maybe not.

    This is based off of a role play with my best friend, they don't have a Wattpad account but I still want to mention them. Just a silly little story that probably makes no sense to anyone but us.

    [Underswap Papyrus x reader] You have a secret. You are the last of your kind, shapeshifter / Human hybrid. The very culmination of your being constantly pleads for you to be honest about who you are, but your kinds law prevents you from doing so. Will you be honest and open about your powers with your new friends, or will you continue to lie and hide in the dark? (Yes the title is a pun, if you aren't aware bonafide means honest/ trustworthy, yes the title contradicts itself it's supposed to show the struggle between logic and emotion.)

    I'm here with a new book based on Undertale, Underswap, and Storyshift. These three main characters are most commonly known as The Bad Time Trio. This book is mostly about their adventures, hardships, and challenges that they're going to face. Hopefully all of you will enjoy reading this book even if you're not a fan of Undertale or is still a fan of this game. [NOTE] I DO NOT OWN ANY OF THE THREE ABOVE MENTIONED AUS. THEY ALL BELONG TO THEIR RIGHTFUL OWNERS. I ALSO DO NOT OWN ANY OF THE PICTURES THAT I WILL SHOW IN THIS BOOK NOR THE VIDEOS. EVERYTHING HERE BELONGS TO THEIR RIGHTFUL OWNERS.

    A reader/underswap papyrus fanfic! In the eight months since monsters had returned to the surface, a lot had changed for just about everyone. Little did you know that a certain monster would change your life. This continuation of an old story I wrote years ago! It's also titled Charming, and is on the account Mopiwx5 if you're interested in checking out the original, though I plan on making quite a few story changes.

    The title says it all. Sorry this is my first book so it's probably a piece of crap. Will contain mature content. Such as, swearing, abuse, general violence.
