So, this is my first Fiolee fanfiction. Actually, this is my first Adventure Time fanfiction. Actually, this is my first fanfiction.

I'm not going to do the whole "no harsh criticism" or "no mean comments", because to me it doesn't matter if it's your first fanfic or your hundredth. A story is a story, so just give me your honest opinions. All reviews are appreciated!

Also, I somewhat tweaked Cake's personality to be slightly more like Jake, just a little bit. She gets on my nerves sometimes. Sorry Cake :3

And lastly, I'm writing in the present tense as a challenge to myself. Let's see if I keep it up. Enjoy!

DISCLAIMER: I don't own the Land of Ooo, or the treehouse, or Fionna, or Cake, or Cake's brick-filled pillowcase, or Fionna's outfit, or Fionna's cocoon-like sleeping bag, or Fionna's backpack, or the contents of Fionna's backpack, or Fionna's sword, or Gumball, or Gumball's outfit, or Marshall, or Marshall's outfit, or the Candy People, or the Candy Kingdom, or the Candy Kingdom Castle, or the Candy Kingdom Castle hallway, or the forest near the Candy Kingdom, or... well, you get the idea. ADVENTURE TIME IS NOT MINE. I do own Everything Taco, though.

"Fionna... Fionna! FIONNA!" Cake hits her sister over the head with a pillow.

"Cake! What the hey, man?" Fionna yawns, rubbing her head. "What have you got in your pillowcase, bricks?"

Cake smiles, "about time you wake up, sweetcheeks! I made breakfast! It's an everything taco!" Fionna looks up in time to see the feline adding the frypan she cooked with to her giant creation, whispering to it, "I love you, everything taco!"

"It's not even six o'clock in the morning! I'm going back to bed." Grumbling, the human shuts her eyes and rolls over.

"Oh no you're not girl! You've got a big day ahead, remember what Prince Gumball said?"

With a heavy sigh, Fionna recalls the earlier conversation where he had told the two he was working on some great experiment that he would need their help with. "Fine." She worms her way out of her cocoon-like sleeping bag and goes to rummage through the closet, looking for something to wear. Finally she come across what she's looking for; a light blue tee, a navy blue skirt, thigh-high white socks, black slip-on shoes, and her bunny-eared hat. I can't go anywhere without my hat.

"You go get changed... I need some private time over here," says Cake, gazing lovingly at her taco.

The adventuress grins, "sure thing. Enjoy your breakfast." Gathering her clothes, the girl walks into the bathroom, emerging less than five minutes later fully dressed. Glancing around, she asks "Um... where'd everything taco go?"

The cat gives Fionna a look of shame.

She can't help but laugh, "you ate the whole thing already?!"

Cake nods, burping as proof. "So," she says, trying to change the topic, "you ready to go?"

"Yep. Just let me get my backpack and sword."

"You don't need to take your sword! We're just baking!" Cake calls out after the young girl, but she'd already gone and returned, fully equipped. She sighs. "Alright then, let's go."

~o~X~o~

"So, what are we doing this 'experiment' for again?" asks Fionna, adding a teaspoon of vanilla essence to the mixture.

"Simple, really," says Gumball, overly dressed in a lab coat and goggles. "We're going to offer these scrumptious muffins, cookies, and cakes to the citizens of the Candy Kingdom and determine which is the prevailing treat, as chosen by the people."

"Right... and what's the purpose of it?"

"There's always a purpose for experimenting! Whether it be for the love of science, or just-"

The adventuress abruptly cuts off the babbling prince, "yeah, sounds mathematical. Will you excuse me, I need the toilet." With an innocent smile, she walks out the door.

"Okay, but hurry back! Things are going to get really exciting - we're going to watch them rise in the oven!"

Fionna rolls her eyes. "Wouldn't miss it for the world," she mutters sarcastically. I can't believe I used to have a crush on that dude! I mean, he's a good friend and all, but... Lost in her thoughts, she walks through the halls of the castle absentmindedly, not knowing what her intentions were or where she was going. Without realising the teenager soon finds herself in the nearby forest. It's not until she hears a rustling bush that she pays attention to her surroundings.

Fionna focuses her attention on the bush, "hello?"

It rustles again, the entire shrub shaking.

"Is someone there?" She instinctively pulls out her sword.

Two glowing red eyes glare back at her menacingly.

With a gasp, she stutters, "w-who are you?"

A low growl eminates from the bush. Suddenly, the eyes disappear, and the shaking stops.

Her eyes darting around frantically, the nervous girl tries to figure out which way she came from. She walks backwards, holding her sword out in front of her, thinking how lucky it was that she'd ignored Cake's earlier advice and taken her weapon. Maybe they're gone.

She listens intently but can't hear a thing. So it takes her by surprise when two hands wrap around her waist. "Hey."

Fionna screams, turning around quickly, ready to fight. At the last minute she recognises the person. "Marshall!"

Soo? Was it good? Was it terrible? And more importantly, what should I do in chapter 2? I desperately need your thoughts!

Thanks for reading :)
