Problems have arisen regarding Finn's health, and it is up to Marceline fix things. But it might take much longer than she is expecting...

My name is Bree. I live in a secluded forest in the land of Ooo. I live with my best friend/sister named Blue. One day we decide to go to the Candy Kingdom and see all of the beautiful things in civilization.But then, danger strikes out and 2 well-known heroes are needed, Finn and Jake. Blue and I might also need to fight. Who knows what trouble we'll get into...

Marceline has never went to the same school for more then a year because of her fathers job. But there is something different about this school.

Set after the events of 'what was missing'. Princess Bubblegum is just settling into bed when she begins to hear soft music floating through her window produced by the Vampire Queen herself. The unexpected lyrics give her no choice but to invite the vampire in. Possibly will become a longer story. Please let me know what you think, honestly. Rated K due to mild suggestive context.

Princess Bubblegum is worrying about her mortality. Immortal Marceline comes to stop her worries. I own nothing.

You find yourself in the Land of Ooo, in your favorite TV show "Adventure Time". Weren't you in Chemistry class before? Now you have to get back to the real world. Or should you stay?

This is going to be a compilation of any one-shot prompts I receive from people or any one-shots I think should be thrown into this set. Some may be AU, some may not be. PB x Marceline Rated T because some people have issues with lady lovin'

Gumball says something to Marshall that he regrets. Oneshot.

Marceline, overcome with boredom, decides to pay Princess bubblegum a visit. little does she know, she'll find out something about the pricess she never expected! rated M for smut and cursing in almost every chapter. you have been warned. please review, and be honest!

A sequel to A.T The Movie. Things were going pretty fine between our favorite couple, Finn and Flame Princess, until Flame King found out about their relationship! Heartbroken, Finn came back to Aaa only to find out that Fionna is dating someone else! What will our poor hero do? Mostly FinnxFionna/ Bunny Bears. Rated T for many things. FINISHED!

Marceline has left for another of her weekend getaways, however Princess Bubblegum is missing her way too much. If Marcy returns, will the Princess be brave enough to tell her how she truly feels?

Finn has been hurt by Bubblegum for the last time. After deciding to leave things people and feelings change. people await his return but no one knows when he will return but when he does, everyone is shocked.

Fionna is a regular high school student at Yandcy Modgink Academdy. She had it all planned out for her school year.What if we add a little sugar and spice to Fionna's life?

Summary: It was true, wasn't it? She was a good person… Right? But if she was... Why had she done all these things? Princess Bubblegum's thoughts when she was turning off her monitors in "The Cooler."

Alternate Universe story set in my D&D Adventure Time AU; a young fire elemental, destined to become a Fire Princess of the new age, visits a wise hermit to learn about the true history of her land. The hermit tells her of the primordial fire giant Surtur, and his rebirth into someone who can make the choices he never could; the fire elemental girl herself.

This is the story of Ghost Princess, before and after her transition into becoming a ghost.

Summary: This episode was just destined to be the inspiration for a Bubbline fanfic. What would have happened if Marceline had followed Bubblegum after she left in a fury? How would our favorite Vampire Queen have handled it?

After failing to protect Raggedy Princess, Finn and Jake go on a voyage to find the one thing that could save her, the Golden Fleece. It's a good thing Finn overcame his fear of the ocean. Parody of Jason and the Argonauts.

Look at cover image for a quick summary and yes this is a harem.

It has been four years since the great hero of Ooo disappeared on one of his adventures, leaving nothing but a memory of his time there, and a heart broken fire elemental.

Era un día como cualquier otro , Finn , Fionna y Marshall iban al instituto , lo que no sabian era que todos su mundo iba a cambiar al salir de ahí

Murmurs have been flying around the Land of Aaa about a dangerous, newly discovered kingdom with a secret. A weapon, they say. Prince Gumball wants to keep everything hush-hush, and winds up pushing this "weapon" onto Marshall for safe-keeping. But it's more than the vamp bargained for. [Marshall Lee x OC]
