Fionna Adventur used to have a good life. But, it all changed. When she needs cheering up, someone keeps leaving notes at her doorstep. It should be the perfect romance, but somehow it doesn't work.

Fiona has a Journal that no one, not even Cake or Beemo could see it, so what was written inside? Well, Adventure time Characters DO ship them selves ;) Marshal Lee X Fiona the Human (The first few chapters are very lighthearted and kinda more humor than not, but they will get much more hurt/comfort once Ashley is involved. I promise)

One day Fionna leaves in the middle of the night to strangle pixies unaware of the person she woke up. But that person decides to do something bad to meet her, and when he does. He meets her other guy friends too, and becomes jealous.

After a bad accident finn begins judging himself and questioning if he really is a hero. So he sets off to try and find a way to redeem himself, and prove he is a real hero. Please review.

Born and bred in the Nightosphere, she's always wondered what the world was like, the world beyond what she knew . She longed to visit the place that her childhood friends, Marshall Lee and Marceline, had disappeared to so long ago. She'd never seen the surface, until now.

The fic where Monochromicorn is an awkward guy and Cake is a sassy gal, and they have a happy beginning.

Just a little side-story to my main works. Set after the Great Mushroom War. Stars my misc. OCs; made them with other people... Don't like; I'm sorry. Will not feature any "true" AT characters...yet. Preview: My name is Hauritori Uzamaki, queen of the Maeni Queendom. I will protect my queendom at all costs; no matter the threat. At least, I hope I will...

Fionna's been seeing a person that everyone claims doesn't exist. Until she gets living proof, and it escalates from there.

Is it a nightmare? Or worse? Is this really what Adventure Time is all about? Who knows. Maybe...

Yes, Marceline and Bubblegum were back together. Yes, Marceline was cool with people knowing. No, she wasn't okay with the fact that a certain lumpy princess was the one informing people about their relationship. *Bubbline*

sapphire was lonly so she wished for some friends but will her wish be changed youll have to find out

Finn and the Ice Queen go bowling.

Some drabble taking place after "Another Five More Short Graybles", where Cinnamon Bun sets the Candy Kingdom on fire. Marceline comes to visit Pb helping recover the kingdom afterwards. Marceline x Princess Bubblegum, Bubbline/Sugarless gum. I swear I'm not trying to shoehorn Bubbline into everything, I just haven't written a fic in awhile and got this idea!
