Summary
A contribution of oneshots for an Undertale Yellow AU from UTY Sub-Reddit called "Mamadillo" made by u/CandidCriticism1730
To put it simply, at one point Dina (The Wild East's Saloon Owner) adopts Clover. That's it, and I love it to the bottom of my heart.
And here I am, making a chapter whenever I can to contribute more fluffiness, or angstfest :V

Summary
I died.
But I soon found out that I'd been transported to a post-pacifist Undertale timeline.
Now as Zen, a goat-like monster. I'll do my best to ensure this world lives on!
....
.....
.............
.................Wrong, something is truly wrong. Terrorist keep attacking. There's something up with Frisk. The most renowned human prophet has gone mad, saying that the world is doomed. The Dreemurs have adopted a new human child named Kris and some of my memories have been erased by a completely unknown being.
I needed time to think, so I went for a walk. But then I saw it, a melting black shadow eerily smiling at me only to disappear right after.
Seriously, what the f*ck? -

Summary
Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
And now, that reason knows about Chara too.Series

Summary
My version of Flowerfell. Frisk, Chara, and Flowey are the main focus because I think this friendship has a (skele) ton of potential that's sometimes overlooked.
I will not be shipping Frisk, Chara, or Flowey with anybody, including each other. In this story, Frisk is seven, Chara is thirteen, and Asriel/Flowey is twelve. I will include a few scenes of Sans x Grillby, and I may include Papyrus x Mettaton, but I'm not sure.
There will be angst, and a closer look at how Frisk's health would be affected by buttercups growing out of their skin. If you don't know what that would entail, please do research before reading. Saying that it isn't pretty would be an understatement.
There will be fluff and fun and shenanigans, it isn't JUST angst.
Edit: I decided to add in an original character. Boom. -
