Exactly what the title says... Undertale one-shots! Cute ships, silly scenes, anything I feel like writing. Literally me just chucking ideas against a wall like a bowl of spaghetti, hoping something sticks so I can lick it off the wall... [written 2017]

Sans Aus x Reader Oneshots (DISCONTINUED) by XxStormassxX

My first oneshot fanfic. This book is discontinued.

Error's book of angst and fluff (finished) by Leffee

Please for goodness heavens, don't comment if you're really young, I had to delete enough of cringy comments. Also please don't leave any suggestive comments, there's a reason why this book doesn't have lemons (aka I'm sex repulsed). Just some one-shots about Error!Sans. Mostly fluff and some angst. Basically me throwing here whatever comes to my mind. Error is short, not because I said so, but because it's canon. In some chapters ships are directly shown, while in others they're not. If that's the case then they're probably friends, but there's nothing stopping you from seeing them as a ship. (Cover belongs to yufy01 on tumblr)

A Book Of UnderTale Oneshots But It's mostly Sans suffering by JDStudios

~Discontinued until further notice (Sorry :< )~ angst, fluff, ships, xreaders, (but mostly angst because haha Sans suffering go brrr) I'll do it all! Except Fontcest, I don't really ship that. And Lemons, limes, or smut. Sorry, I'm not a sinner :/ But this book is basically me just putting down random oneshots that come to mind! Lot's are inspired, others are my ideas! Anything inspired I will put credit to the person I was inspired by! There will also be oneshots that I've already written thrown on here! (Avalanche, Stop or suffer, etc.) If anyone actually reads this and has a request, just comment it below. Alrighty, let's start! (btw none of the art in the stories are by me, unless I say so.)

A bouquet of oneshots, by me, for the lovely reader who took their time to read this! Requests are gladly accepted, but be warned, I procrastinate a lot and I'm a very busy person, so they will take a long while. Slow updates! Like very slow
