Chapter 1:

Part 1:

"Oh my strawberry glob! What kind of stupid wish was that Jake?!" Marceline snapped at Jake, whom shrugged with a smile.

"Oh come on. Sending us all to an Alternating Dimension, isn't that wonderful?" Jake murmured, a smile on his face. Finn sighed.

"I don't think so dude. Can't we like, mess up the time line or something-!"

"Finn!" Marceline snapped. Don't be a buzz kill. How about the three of us just give it a try? Now, where'd my bass go?" She said. The three of them looked around, trying to find the guitar Macy had dropped. Finn whistled. "Here it is. I've got it." He said. He bounded over to the red ax guitar, peeking out of the low bushes a little. Marceline turned around to watch him retrieve it, but she hissed angrily when he bent down to touch it.

"Finn-! No!" She whispered, but when Finn's fingers brushed the smooth wood, the guitar was abruptly pushed forward, hitting him in the stomach hard. "Ahhh!" He said, falling backwards and hitting the ground hard. "What the-!" He and Jake started screaming when a tall, dark figure dressed in a dark black cloak floated upwards out of the bushes and above Finn. Jakes fear of vampires got the best of him, and he ran behind Marceline, frowning and whimpering.

"Hiss." He said, baring his teeth. Finn got up on his two feet, backing away quickly. "Hmm…. I haven't seen one of you in a while." Marceline said, biting her lip a little as she tried to see through the vampire's black cloak.

"One of me, eh? I show you me." He snapped, he flew quickly at Jake and Marceline, who jumped out of the way just in time. Jake hit the floor as the male vampire's feet almost skimmed his forehead. "G-yah!" He said, throwing his hands over his head.

"That doesn't even make sense!" Marceline snapped at him, and then kicked off from the ground. She levitated in mid air until she was feet to feet with the blood sucker, who stopped his flying attack to stare at her.

"You float too?"

"Duh. I'm a vampire too." Marceline sneered, throwing her long black hair over her shoulder. "Whoa." Finn said, sitting next to Jake as the both of them stared up at the two of them.

"Who are you?" The cloaked figure said, narrowing his eyes beneath the dark and scary cloak. "My name is Marceline, the vampire queen."

"No your not. Because my name is Marshall Lee, the vampire King."

"Your lying."

"No I'm not!" Marshall snapped, grabbing a fist full of his cloak. He ripped the cloak off and let it fall to the ground. Finn and Jake gasped.

"He's not lying. Marceline, he's you! But he's a boy! He's your-!" Finn started.

"Perfect and alternate self!" Jake finished, and both him and Finn nodded feverishly.

"What?" Both Marceline and Marshall Lee said, and then flew closer together so that they could get a better look at each other. "I don't see it." Marshall said as they both twisted perfectly to look at each other upside down together. They got closer till their noses were touching, and wrapped their bodies around themselves.

"Ew!" Finn said, but Marshall hummed. "You have the same eyes as me, and my good looks. Who are your parents?" He asked her, and she smirked.

"My father rules the Nightosphere."

"No. My mother rules the Nightosphere." Marshall said with a wide smile.

"In your world. But we entered from Prismo the wish makers world. We live in an alternate dimension." Jake yelled.

"Oh… You mean Prisma?" Marshall asked. He took a picture out of his pocket and showed Marceline the picture. They were both still hanging upside down, and she adjusted it so that she could see it better.

"Hmm…Yep." She said, looking at the pink Prismo with pink pigtails. He wrapped an arm around her waist and the both of them started floating downwards.

"Cool, so we're kind of like… Lovers from another world."

"Don't you mean siblings-!"

"Oh come on, now its weird." Marshall said, dropping her. She flipped back into a standing position as she floated downwards onto the ground.

"Um, hey. Marceline the boy version, would you happen to know our super cool alternate reality partners?" Finn said, and Jake nodded excitedly. When Marshall and Marceline were on the ground, they both narrowed their eyes at the two.

"Kids." Marshall and Marceline muttered under their breath. "You know dudes… I think so." Marshall said, humming. He stared at the white hat on Finn's head. "Take off the hat."

"But why?"

"I said take it off!" Marshall snapped, his eyes widening demonically and turning yellow like a bat's. He flicked his tongue out when Finn squeaked, Marshall's tongue was skinny and vampire like.

"Okay I'm doing it." Finn said, he ripped off his hat. Golden tuffs of blonde hair that flowed down to his shoulders, shinned in the sunlight brightly.

"Yes. You're the product of my friend who is ultimately in love with me. She'll deny it, but she's always flirting, you just got to look. Marceline, look out for that kid." Marshall whispered, and Marceline laughed. "I think I can handle him."

"Yeah." Finn said, not amused. "What's our cute lady names?" Finn said, and Marshall rolled his eyes. "Fiona and Cake."

"Fiona and Cake." Both him and Finn whispered. "Cool! Take us! Take us to them oh great boy Marceline."

"My name is Marshall, not boy Marceline! Get a grip on yourselves." Marshall Lee snapped. "Okay, are we going to Fiona and Cake's house?" Marceline asked.

"Yeah. Grab a species and follow me." Marshall Lee said, and then flew forward fast. He gripped Finn by the shoulder and then he was flying fast. Marceline picked Jake up and her bass guitar, and then flew fast after Marshall Lee. When they were shoulder to shoulder, they started snapping at each other over Finn and Jakes screams. "Hey, that's my Bass!" Marshall snapped.

"No, it's my bass." She snapped at him. "No, it belongs to a long line of my parents from the Nightosphere-!"

"No, its my parents that have the long line-!"

"Shut it-!"

"Please don't fight! We're over a hundred feet in the air!" Finn whined. Jake nodded. "Yes, please don't fight. Don't drop me!" He said, and the both of them snapped.

When they reached the familiarity of the tree house, they both dropped the boys. Finn and Jake tucked and rolled when they reached the ground, and Marceline and Marshall Lee slammed into each other on the ground, wrestling and fighting each other.

"Hey! Hello, anyone home?!" Finn yelled. "Hiss!" Marshall Lee and Marceline both shouted, scrambling onto each other on the floor.

"Ooh baby." Finn and Jake heard, and Cake poked her head out of the window.

"Who is it?" Fiona called.

"It's Finn and Jake!" Jake shouted. Finn chuckled. "Yeah, and Marceline and boy Marceline-!"

"I said my name was Marshall!" Marshall shouted, pushing Marceline off him. He swooped towards Finn with a loud hiss, but Jake stretched super high, grabbing Finn in his fist and lifting him out of Marshall's reach and towards the clouds. Before Marshall could follow, Marceline dove forward and smashed into Marshall's side, making the both of them crash into the ground.

"Stay away from my friends!"

"You can't tell me what to do-!" Marceline smacked him against the cheek. "Ow! My cheek meat!"

"Marshall!" Fiona snapped, running out of the house. He hissed hard and dove at Marceline, but Jake grabbed her with his foot and threw her upwards, and she flew and levitated upwards above the tree house. Cake came out behind Fiona as they stopped next to Marshall, who glowered at Finn, Jake, and Marceline got down to ground level.

"Hello… friends or foes?" Fiona asked. Jake laughed. "Look Finn, I'm a cat."

"Excuse me?" Cake said.

"Um, do you know Prismo, I mean Prisma?" Finn asked the two girls. They nodded. "Oh sweet biscuits, your from an alternate universe, aren't you? Prisma's always inviting people to their alternate universe parties."

"That's right." Marceline, and gripped the bass guitar hard. Marshall's eyes glowered. "Hiss!"

"Marshall calm down, you bad little boy." Fiona snapped at him, and he slowly backed off. "Fine, fine. But I'm getting it back before you leave-!"

"In your dreams blood sucker." Marceline snapped. Marshall snapped at her angrily. "You're the same as me." He snapped.

"Except I'm cooler." She said, she strung a long B cord strongly, letting the vibrations echo throughout the field. Then she started playing the guitar awesomely, and Marshall shrugged. "Not bad."

"Silly little boy. Anyway, Fiona you're a little boy."

"I'm not a boy. I'm a man!" Finn said, pumping his chest. Fiona, obviously closer to Marceline and Princess Bubblegum's age, smiled at him. "Sure you are." Cake said, and Jake guffawed.

"Anyway, I've got so many questions. Do you know Flame Princess?" Finn asked, striding over to Fiona. "You mean Flame Prince?" Fiona asked, a smile on her face. "Yeah, what do you think of her, I mean him?" Finn said, and he and Fiona, plus Jake and Cake moved inside the tree house. Outside, Marshall and Marceline started singing a duet together. "Well, he's a pretty radical dude. He and I are friends, and I like him.

"You look like me. You act like me, so why can't you be me? Or be with me," Drifted in through the window. "Hmm, they seem to be getting along with each other now." Fiona said, a smile on her face.

"Really, wow." Finn said when he looked up at the window. Marceline and Marshall Lee were spiraling around the yard now. "That's awesome. You know, Jake and I were almost vampires." Finn said to Fiona. She frowned in curiosity.

"Really, what do you mean by almost?"

"Marceline tricked us into thinking she had changed us into vampires, but it went too far and we almost died. But then we went back to her house and watched TV with the killer ghosts. But they didn't want to kill us anymore, they just wanted to watch heat zone or something."

"You mean Freeze zone, cool dude?" Fiona asked, and Finn nodded. "Oh, yeah, that's cool. Do you know PB?" Finn asked. "I know PG."

"Who's that?"

"Prince Gumball of course."

"Oh cool, I know Princess Bubblegum." Finn said, and Fiona laughed.

"I like your hat, hey! Do you have a Bemo?" Finn asked curiously, and Fiona chuckled. "Yes, but she's on a trip to the North Pole. Hey, I need to bring you into a Ooo today. We should all visit the Candy Kingdom and have fun with buddies today. I know PG would be happy to see you." Fiona said with a nice and neat nice. Jake and Cake were having a different conversion in the corner.

"Yeah, you shouldn't scrape your nails. Wandapoliton says you need to clip them nice and neatly, and then just use a soft sponge to soak them. Soak the nails for minutes at a time. I mean look at these pink ones." Cake said, holding up her hands.

"Yeah, I can't tell you how many times I went out and had crusty nails. It very embarrassing." Jake said, and then shivered a little.

"So… You're a cat." Jake said, and Cake nodded. "Yep, and you're a dog."

"Curious, have you met Rainacorn yet?"

"Who?"

"Rainacorn. The love of my life, the mother of my puppies?"

"Oh! You mean Maleficorn. He's a type of magic horse."

"Cool! So…. Any puppies yet?"

"Do I look like a mother to you?" Cake said, putting her hands on her hips. She raised her eyebrows up high.

"Okay, this just got awkward." Jake said, and then walked over to Finn. "I'm ready to go to the candy kingdom now." Jake said. "Us too. So, tell us a list of your friends, and we'll tell you their counter parts." Finn said excitedly. The four of them walked outside slowly.

"Okay… Um... Lumpy Space Prince-!"

"Lumpy Space Princess-!"

"Fire queen."

"Fire king."

"Flambino Queen."

"Flamebo."

"Ice Queen. Well she's definitely not a friend. She's evil and wicked and stupid. Always kidnapping Princes and such." Fiona said. Finn laughed suddenly.

"Ice King. He's not a friend. He's evil and stupid, and he's always kidnapping Princes and such." Finn laughed, the four of them laughed joyously.

"Ever heard of the Magic Woman?" Fiona asked Finn.

"No, but I have heard of Magic Man." He said with smile. Above their heads, Marshall and Marceline both had their hands on the guitar, trying to pull it the other one's way. "It's mine, mine, mine, mine, all mine!"

"Not a chance, not ever, not now. This is my guitar, it holds the key to my heart-!"

"Then give it to me and with this key I'll keep and you will live like the start-!"

"Of our great, relationship-!"

"Stop singing you two! We're traveling to the candy. Marshall and Marceline looked down at them, glares on their faces.

"Hey!" They heard, and turned around.

"Oh my goodness! You?!" Fiona said.
