Undertale:Secrets
Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great.

Undertale - Fighting To Stay [Frans] [Book 3]
So, monsters and humans have been living together on the surface for quite a few years now... That's an accomplishment! No resets, no new timeline. Just a future continuing forward like everyone could have possibly hoped for. However, not everything is hopeful. You can't expect to live a life where everything is sunshine and rainbows. Even with no longer having the threat of someone like Chara, things can still happen when you least expect them to. You can't always have your "Happy Ending".Complete

Sans X Reader // You're Too Punny
Smol thing I guess. I don't own Undertale (obviously), but I do own all of the art in this book (as the first A/N states). This is my first fic. I update as often as I can, especially on most weekends. Don't be afraid to comment if you have something to say.Complete
He's Mine (COMPLETED)(Yandere Papyrus)
(UnderTale rightfully belongs to the amazing Toby Fox, I am not creative enough to make that masterpiece. There is a person named symphysins who drew some work of Yandere UT! Papyrus for Sans, and I really liked the idea of a creepy UT! Papyrus and decided to write a short story on it. Also, Frisk can't reset, she never had that ability. The cover is my own art.) "Why is everyone I date dying?" Sans asked, covering his eye sockets. "Am I cursed or something?" "I'm sure you're not cursed, Brother!" Papyrus said, patting his back. "T-There might b-be a Yandere on t-the l-lose!" Alphys piped up. "A Yandere?" Sans asked, tilting his head. "What's a Yandere?" ~~~~~~ Sans felt like something was wrong. Everyone he tried to date ended up dusted, and he couldn't figure out why. So, when Alphys explains to him what a Yandere is, he realizes he might be someone's Senpai. Determined to stop this endless cycle, he teams up with his friends to try and find this psychopath. If only they knew he was closer than expected.Complete

Undertale: Tales from the Dreemurr Family
Join Frisk, Chara, Asriel, and their younger sister, Aria, as they share many happy moments together! 11 months after Frisk's most recent True Pacifist Run, they, Chara, and of course Goatbro himself (AKA Asriel Dreemurr) receive a wonderful surprise in their new sister, Aria. Eight years have passed since then, and the four children are having all sorts of fun with each other! Comment if you like the story, or if you have an idea of what you'd like to see the Dreemurr family get into! Disclaimer: I do not own the game "Undertale," or the characters that appear in the game. Aria is my OC, and is not an actual game character. Note: Updates may be irregular, due to the fact that I have no set schedule. Also, I may edit chapters that have already been published, so you aren't alarmed when a chapter changes.

Undertale X Reader
You woke up on bed of golden flowers without having anything to remember. Going to an adventure where you met with many monsters to go home. Easy, right? Not really, actually but anyways! - I do not own any characters from undertale -i did this only for fun, don't judge me -this story is abit (alot) angsty so be prepared~ -Chara is evil(sorry i just had to-)Complete![(Dancetale) Better Dancing Together - Sans X Reader [DISCONTINUED]](https://img.wattpad.com/cover/75664096-256-k467287.jpg)
(Dancetale) Better Dancing Together - Sans X Reader [DISCONTINUED]
[16/08/17] Edit- Okay. Warning. This was written carelessly? The grammar isn't too bad, but it isn't too great either. This is also discontinued. Go to @Lilliyona to see the continuation. Bad jokes were also made cause I didn't know how to do jokes. So there's a lot of cringe, probably. It isn't as bad as my older books, but it's still bad in my opinion. That's all. Goodbye. Heyo, too lazy to explain anything! So yeah, all I can say is just, this will be in High School so meaning teen Sans and everyone are teens except for Toriel and Asgore! And yes it's Dancetale like what it says in the title! Chapter one might wouldn't sound like it would be Dancetale, but trust me, I have plans! And I know that, it also may sound like another cliche type of Highschool crap, but I promise things won't be like that! Hope you enjoy~ I do not own Undertale nor Dancetale. I do not own the art for the cover. (Edit- Warning: One New Chapter Every Week Or Two. Might Contain A Few Swearing Here And There. Cringe At The First Few Chapters-in my opinion now that I've grown up a bit-.)Complete
