Ooo and Aaa

Hi! My first Adventure Time Fanfic! I decided to make this because of how close it is to Halloween, and I'm listening to Fright Ranger's songs ''Werewolf Boyfriend'' and ''Sexy Vampire'', which always seems to bring me into a ''spooky'' mood. And Chyna Anne Mclain's song ''Calling All the Monsters''. Disclaimer Time! Ha! It's a joke.

Disclaimer: I don't own ANYTHING!

It was a mid- October night. Finn and Jake were visiting Marceline The Vampire Queen in her cave home.

''Jake, over here man.'' Finn called to his brother.

Jake shuddered. He still had some fear of Marceline, after all she did almost kill them, twice, he'd been counting. And he felt that number would grow eventually.

They entered the cave, holding a flat rectangular box with red and white wrapping paper over it, and on top was a big silvery-white bow. On the tag it said: ''To Marcy, our best vampire friend.''

Finn walked up to the door and knocked.

''Jake, hid the gift.'' He whispered.

''Oh, right.'' He said putting it in Finn's backpack.

Marceline opened the door to be greeted by Finn and Jake's smiling faces. ''Why so smiley you two?''

Finn stopped smiling, frowned for a second and then grinned like an idiot.

Marceline looked quizzically at him,'' Okay, silence is cool.''

''Here Mar Mar, we got you somethin'.'' Jake said, getting the present out.

Marceline looked puzzled,'' What's it for?''

''Remember when that Earth Golem attacked the Tree Fort and you helped us stop him?'' Finn asked

''Oh yeah, that was fun.'' Marceline smiled

''Fun? That thing nearly killed us!'' Jake threw his arm around in a goofy manner.

''So….. we got you this as a 'thank you' present.'' Finn continued, pretending not to hear Jake. He took the present from Jake and handed it to Marceline.

She opened it and her eyes lit up with excitement,'' Oh my Glob, you guys, are these-? Are these….. Oh awesome! Vintage rock posters! You guys, where'd you find these?''

''Choose Goose.'' They said together. Yes, that odd merchant goose had found these a while back and didn't have anyone that wanted them. When Finn and Jake went there, once they set their eyes on them, they just had to get them for Marceline.

''Thanks Finn, thanks Jake. You guys rock!'' Marceline said, leaning against the door frame, folding her arms around her new posters.

''Hehe yeah.''

RUMBLE!

Jake leaped up into Finn's arms, who just dropped him.

''What was that?'' Finn asked.

''Let me see.'' Marceline said, floating up and out of her cave into the sky. She was about 30 feet up when suddenly….. She started falling like she was made of lead! Finn caught her before she hit the ground.

''Dude, she's out cold.'' Finn said, lightly smacking the side of her face to get her to wake up. Nothing.

''Let's take her inside, man.'' Jake proposed, opening the door.

Once inside, Finn set Marceline on her bed in her room, and then joined Jake in the living room.

''Jeez, what could cause her to do that?'' Jake asked.

''I don't know. Hey, man did you see that weird blue glow too?'' Finn asked.

''Yeah, maybe that had something to do with it.'' Jake shrugged.

Finn shook his head, uncertain and confused.

PIT PAT PIT PAT PIT PAT

Someone was outside. Finn went outside to investigate the sound.

When he rounded the corner—

''BOO!'' a voice hollered from nowhere.

Finn shrieked, falling to the ground.

Girlish giggles filled the echoing cave.

''I didn't mean to freak you out ,Finn.'' The voice spoke again.

Finn recognized whose voice it was. Flame Princess. What was she even doing here?

''Good prank, FP.'' Finn laughed it off.

Flame Princess leaned in to kiss him quickly, but Finn stopped her.

''No, not right now. Maybe later, alright?'' He said.

Flame Princess looked slightly upset, but nodded to signify she understood. ''I saw what happened to your friend Marceline. Is she sick?''

Finn shrugged. 'Psh, she's a vampire, they don't get sick, at least not that I know of. Some weird junk beens happening lately. First, this strange rumble goes through Ooo, and then this weird blue glow appeared just over those hills. Next thing I knew, Marceline is falling out of the sky like a rock.''

''A blue glow? Oh no!'' Flame Princess sounded scared.

''What, what is it?" Now Finn sounded scared.

''Well, my father used to tell me stories when I was little about a place called 'Aaa' when I was in the lamp. It was actually a very real place. They say when our worlds converge, a blue glow will form around a certain part of each world. Each person has an 'other half' on the other side of the glow, if that person steps through it, the person in our world will get the recoil. You have another half, I do, and everyone else does as well. You're friend's other half must've stepped into our world.''

Finn had a vacant look on his face, but he nodded slowly to show he understood. ''So maybe if we find this person and throw 'em back through the portal, then Marcy will get better?''

''It's not that easy. Marceline's a vampire right? So what if her other half is human? Like you? But, they still know how to fight like her?''

Finn's face fell. ''Crud Cow!''

''Let's go find this person. We'll get some answers then.''

Out near The Tree Fort…..

A shadow was hovering around and around the big old tree.

''Where are they?'' The figure asked, floating down to the ground,'' This is weird, first that blue light, I step through it and now I have no idea where everyone is. Ugh! This is great, just perfect! And to top it all off, I have no idea how to fix this!''

''Hey fool! Get away from my house!''

''Huh?" The figure turned it's head to the sound of the voice. ''That doesn't sound like Fionna or Cake. No. It's sounds like a boy.''

''I said ' get away from my house'!'' The voice yelled again, but it sounded closer than before.

''Who are you? Show yourself!"

''Hiya!'' Finn yelled, jumping out of nowhere and kicking the figure in the face.

''Gah!'' The figure groaned, rubbing its face.

''Ha! Hiya!'' Finn yelled again, swiping with his Demon Blood sword.

''Whoa!'' The figure yelped, dodging the sword, ''Chill out man!''

''Why should I?'' Finn asked, swiping again.

The figure caught the sword in between its hands,'' Because, I'm not going to hurt you.''

The figure leaned in, revealing his face. Pale skin, short pitch black hair, two fangs, and the same eyes as- No!

''No way.'' Finn said, shocked,'' You look like-. Are you a vampire?"

''Huh?'' The man blinked,'' Of course I am. I have fangs don't I?"

''Finn? Are you okay?" Flame Princess asked, lighting up her hands with fire in case Finn needed help.

''I'm good. It's just-.'' Finn turned his attention back to the man, taking back his sword,'' What's your name?''

''Okay, random question. My name is Marshal Lee.'' The man answered, floating up and then flipping himself upside down.

Damn. I am pretty proud of myself here. I guess that would answer why Marcy dropped like a dead fish huh? Ha, awesome. I'll do my best to keep up with up-dating this story.
