A/N: I'm so Happy that so many of you who were with me for my Marshall Lee journal adventures have followed this story as well! And also all the overwhelmingly positive feedback to my one-shots! I hope my stories continue to tickle your collective fancy! If its possible, I'm already even more in love with writing this story than I was with TRRRNMOML and I hope that translates into the words. Also I seriously watch Bad Little Boy like at least twice every day. Don't be surprised if that whole episode make it into this story. Seriously I can't even describe the feels I have for how perfect that whole thing was. Ok, ok I'll stop this long rambling train to nowhere and let y'all get on with reading! PLEASE REVIEW!

Fi woke before the sun was even up next morning and began to pack all the string into manageable packages for carrying to the vampires humble abode. She trudged across the Verdant Planes, through the Candy Kingdom, towards the Lost cliffs and the rocky canyon where Marshall Lee hid his home.

While in the candy kingdom a kind candy person offered her a wagon, which she gratefully accepted and continued her trek. When she finally got to the mouth of the cave and hauled every last bit of string up she was exhausted. That vampire better flip out or she would.

She let herself, quietly, into his house, making sure to shut the door without so much as a creak, and thanked her lucky stars that she'd been hanging around the vampire so much, which meant he was attuned to her presence and wouldn't wake up sensing a threat. The girl spent hours upon hours tying string to EVERYTHING she could think of. Well, except breakable stuff, she didn't want to piss him off, just annoy the stuffing out of him. By late afternoon, Marshall's livingroom was a spider web on steroids. He wouldn't even be able to float down out of his bedroom without scissors! Fi was torn between staying and seeing the undoubtedly awesome reaction and possibly getting her butt handed to her, or leaving a note that marked this as her handiwork. The girl deliberated a little longer and chose not to stay. She scrawled out a cheeky little note and left it on the kitchen table, taking off for home well before the vampires usual waking hours. When she arrived back at the tree fort she was tired and hungry and maybe a little stinky, but she was satisfied and that's all that mattered so she grabbed some left overs from the fridge, ran herself a bath, and vegged out.

Marshall Lee woke up that evening still in good spirits from his fortnight of pranks with his best bud. He rubbed his eyes and rolled over his bed and floated lazily to his bathroom where he proceeded to get ready for the night. When he finished his shower, he floated out of his bathroom, towel drying his hair and he pulled on some clothes. He began descending into his livingroom while still pulling the shirt over his head when his downward momentum was stopped. He grunted in sleepy confusion and pulled his shirt the rest of the way on and continued to attempt to leave his room. When he was thwarted again he chose to glare down at his feet and whatever was stopping them from their downward travel. He didn't know what he was expecting, but it certainly was not what appeared to be a bird's nest of crisscrossed string. What. The. Flip.

He trudged (or the floating equivalent of trudging) over to his desk and searched for his scissors in order to cut his way down to his kitchen. All he wanted was some breakfast. 'Who even did this?' He thought, his aggravation increasing with every second he couldn't find the simple hand tool he was looking for. After a few minutes, he gave up his quest for the scissors and just shifted his hand into a blade. Demon powers were quite handy sometimes. And as the rest of his livingroom came into view, he had to laugh. The whole thing, not just the entrance from his bed room, had been carefully tied up in string. He noticed that the person who had done it had avoided anything breakable, and for that he was grateful. He carefully cut his way through the livingroom, tripping and tangling in string, and wondered who exactly had done this, though he had some ideas.
When he finally reached the kitchen, he saw the note the bunny eared human girl had left on his table.

"Marshall Lee,
You're a butt so have some string. My pranks are clearly the best!
Fionna."

'Oh, her pranks are the best are they?' The King thought to himself. Well he'd show her who was the best. This was a challenge if he ever saw one, and it was definitely a challenge he could meet. He fished around in his fridge for an apple and began to clean up the mountains of string that now took up residence in his home. Unfortunately this took him ALL night, and bits and pieces of the string still stayed stubbornly tied to some of his furniture. He supposed he wasn't actually in too much of a hurry to get Fionna back. Maybe he would lure her into a false sense of security. He decided to spend a week and figure out what he would do to get back at the younger prankster.

Marshall spent a good amount of that week in the candy kingdom bouncing ideas off the candy prince, literally and figuratively. The vampire had taken to writing these ideas down and, when deemed ineffective or otherwise lame, he just balled them up and threw them at his friend.

"I thought you were trying to prank her, not annoy me!" The pink man protested. Marshall Lee shrugged.

"Two birds with one stone?" He glanced nonchalantly at the prince and was pleased at the mildly annoyed look on his face.

One day, while putzing around the candy kingdom, taking a break from plotting and annoying PG, Marshall Lee ran into Fionna and Cake picking up candy litter for lunch. He flew above their heads til Fi noticed the shadow from his umbrella. She looked up as a grin curled his lips.

"Oh hey Marsh!" She grinned back.

"Hey girly." He replied with a fanged smirk. She swatted at his foot (that's the only part of him she could reach) and frowned.

"Don't call me girly, Marshmallow" he chuckled and lowered his feet to the ground uncomfortably close to the younger teen and brushed her bangs out of her face, almost lovingly.

"Thanks for all the string." He said, voice deep and eyes glinting. Maybe he didn't get the drop on her in this prank war, but he could definitely make her uncomfortable. Her face steeled as if she recognized the challenge in his voice and she grinned back at him.

"It was nothing dude, plenty more where that came from." She said shrugging and popping a discarded candy sock into her mouth.

"Oh there will be plenty more, that's for sure." The vampire gave another lopsided smirk and kicked off the ground. "I'll see you around ladies" and he gave a short wave as he flew off towards his cave, he finally had his plan and he just had to wait for the proper time to execute it.

Over the next few days he popped into the tree fort multiple times. This served two purposes, casing the joint and also throwing Fi out of whack, making her complacent. Marshall Lee may have also missed the young adventurer, but being the lump he was he would never acknowledge or voice anything close to attachment to the girl. Hell, he would never admit to any attachment to anyone. Attachment is weakness and weakness is intolerable. This train of thought, subconscious though it may be, made the Vampire King irritated. It only irritated him further that he didn't understand why he was irritated and so he decided, in order to blow off some steam, he would put his plan into motion.

He called in favors he had accrued over the millenia from many monster families and basically assured Fionna and Cake would not be home for a day or two. He packed two rather large, heaping boxes full of the left over string and set off for Fionna's place. He hid on the roof til he saw the girls running off to save the day and he snickered quietly to himself, knowing what they'd be in for all day. As soon as they were out of sight he swooped in through the door the girls so carelessly left open and got to work.
