It was a normal day in the Land of Ooo, there were no adventures to go to, no princes or princesses to save and it's been 2 years since Ooo was merged with its counterpart world. It was noon; Finn and Fionna were sparring with their sharp swords while Jake and Cake were preparing their lunch for the day.

"Fionna! Baby Cakes! Finn! Muffin Top! Lunch's ready for y'all! Now stop playin' and start bitin'!" Cake shouted through the open window as Jake sets the table for four. Finn and Fionna raced to the front door, they laughed while they ran but unfortunately for Finn Fionna went first. "Ha! I beat you again! You've gotta exercise those legs of yours if you wanna beat me, bro." Fionna bragged and in reply, Finn frowned and thought I'll beat ya ~ You'll see.

"FINN! FIONNA! Quiet the yapping and start dining." Jake ordered and the two obediently sat onto their chairs and ate their lunch. In the middle of eating they here repeated soft knocks on the door.

"Hey Fionna. Baby… Could get the door?"

"Oh. Yeah. Sure." She stood up and walked to the door. She reached out to the door knob and opened the door reveal a teenage girl who had long scarlet red hair that reached her mid thigh, she had brown colored eyes and she has pale peach skin, she wore black tight long sleeves, denim shorts, and black doll shoes. She carried a guitar bag on the back. She's got a friend with her; her companion looked a lot like her but the companion was a boy. He also has scarlet red hair but it was short. He also has brown colored eyes and pale peach skin. He wore a white long sleeve v-neck shirt, khaki pants and a pair of black converse. The guy carried two luggages that seemed to be where their clothes are. The girl smiled at Fionna and the boy's face was straight.

Fionna's P.O.V

When I opened the door, a girl with long red hair stood in the front door. I was speechless. She was so pretty when she smiled at me and the guy was flippin' handsome! I didn't know how get myself to speak when I'm too stunned looking at their pretty faces. And they look… Well, human. Like Finn and me.

"Hey. Uhh… We were just wondering if we could crash here for the night. You see, we're new around here and we just wanted for a place to stay for the night." She smiled again and the only thing that I manage to give as a reply was a nod. COME ON FIONNA! THIS IS NOT THE TIME TO BE A BUM!

I shook my head and replied nicely, "Uuhh… Sure. C-come in."

"Hey brittle butt! Who was at the-" Finn stopped talking when he saw the two new guests in the living room.

"Hey Finn, these are Christopher and Christine Jack. They needed a place to crash. They're new around here." They waved politely at Finn and Christine smiled at him. I saw him blush and I snorted at this.

"Oh. Ok. I'll just tell Cake and Jake that we have guests at home."

"Yea. Ok." I turned back to Christopher and Christine.

"So, where are you guys from?"

"Oh. We're from the Night O'Sphere." Christine answered and grinned.

"What? The Night O'Sphere? So…" I was ready for combat. I was ready to pull out my crystal sword "So you're evil!"

"Oh. No! NO! NO! We're actually humans who lived there." Christine explained.

"We were the only humans there and our parents were killed by a bunch of wackos who wanted to eat the guts out of us. Well, mainly, they wanted our blood since it's a rare thing to find in the Night O'Sphere." Christopher explained and Christine continued after.

"We were supposed to be blooded when we've come of age but something unexpected happened. One of the citizens of the Night O'Sphere happed to walk passed by us and he sniffed out that we were humans and our parents… hk… they…" Christine was in the verge of tear and it seems that she could not continue their story.

"Our parents had to protect us and they died while trying. They used a ritual that only vampires can uses to transport to the world above but there was a chase. It needed a sacrifice. Since there were two of us, mom and dad did not hesitate to use it. And there will be no chance of me and Tin to become a vampire." Christopher said with a serious face but his eyes was filled with anger, sadness and pain. I was horrified and sat beside Christine and rubbed her back while she was crying. When suddenly, she sat up straight asked with head high "What time is it?"

"Oh. It's 5:45 in th-"

"OH NO! OH NO! THAT MEANS THE SUNS GOING DOWN! TOP! I need to go okay. I'll see you tomorrow. Fionna, please take care of him. Thank you." She bowed before heading out the door.

Christopher laughed at this. "She really does know how to break the ice."

"Uhmm… Christopher, why was Christine in such a hurry?" I asked curiously.

"Please, call me Top and her 'Tin.' We go by nicknames. Ours names are too long to say." He chuckled while scratch the back of his hair facing me, which looked cute but he didn't even bother answering my question.

"So, Top. Why was she in such a hurry?"

"Well, you see. She has this curse that changes her form when the sun sets."

"Oh? What happens?"

"She turns to a fish person." He said seriously as leaned on the couch and looked out the window. I gasped.

"You see, there was this witch that I… Well, pranked and she got mad and tried to cast a curse on me but Tin was there to catch for me even though I didn't want her to. And now, she always had to go to the water to before she turns so she'll become a mermaid instead of having a fish head and a human body."

"Well, why don't you find a way to stop the curse?"

"We did ask a witch friend of ours how to get rid of it but there was only one antidote. A kiss but not just any kiss. It has to be from the one who she loves and the one who loves her back."

"Oh."

"Aww… That's too bad honey. I really wished that we can help." Cake butted in our conversation and Finn and Jake was with her.

"Cake, since when were you listening to our conversation?"

"Oh? You didn't realize that? I thought you knew. They've been there since well, Tin started the story of how we got here." Top explain.

"Oh. I see." Was I managed to say.

"Bro, you can stay here as long as you like." Jake offered.

"Hey, did you guys have lunch? We could totally bring eat some to Tin." Finn suggested.

"I think that would be great." Top agreed and he stood up and settled their luggage by the couch.

Fionna and Cake got the food ready and head out and the three boys followed after. They walked to the nearest sea side there is. They walked silently. Finn thought he should break the ice but Jake beat him to it.

"Hey Christopher, how old are you anyway?" Jake asked curiously.

"16. Tin is too. Well, she's suppose to be older."

"What? How could you say that about your sister?" Cake protested.

"Well, it's true. She's supposed to be a thousand years old but something happened before she was blooded." Christopher explained.

"Wha-? You mean she was supposed to be a vampire? Then why –?" I was cut off…

"I think, Tin should be the one to tell you guys about that. She'll hate me for blabbing about her life without her knowing." He smiled at me. I just nodded in reply.

Christine's P.O.V

Arrrg. Here we go again. I hate this. If only Top didn't prank that crank old hag I wouldn't be facing this consequence now. Oh, well. I have to accept that I won't get rid of this stupid curse off me and that I won't ever be a vampire. At least I inherited some vampire blood from dad but that still isn't enough. I need to be blooded if I want a full power of a real vampire.

"Maybe I'll just end up like Auntie Silvia." I muttered out loudly.

"Who's this Auntie Silvia, little mermaid?" A strange unfamiliar voice whispered out.

"Who's there?" I shouted. I wish I didn't have this stupid tail so, I could beat the crud out of this maniac.

"Oooh… Scared are we?"

"Teh… Who's scared? Definitely not me."

"Tell me, what's a pretty mermaid like you doing in a spooky cave like this?" My spine was beginning to have chills as the cold wind blew through my skin. I was just wear a bikini top and my hair was tied up.

"I have my reasons. What're you doing here? And SHOW YOURSELF!" I shouted as strong as I can.

"Alright but you'll regret it little mermaid…" I heard him chuckle.

I laughed. "Believe me, I've seen the worst."

Then I saw a pair of crimson red eyes appeared from the shadows. It flew and drew closer to me. He was hissing at me. It was horrid but I've seen this kind of creature before. It's a vampire way of scaring of the unwanted of his property.

"Tch. You don't scare me vampire." I chuckled.

"Wha- How did you –?" He slowly transform back into his… well, somewhat human form. He was gorgeous except for the fact he was a jerk trying to scare me off. It's a good thing that I grew up in the Night O'Sphere, if I didn't I would probably be a woos a while ago.

I laughed. "It's not the first time I saw vampire turned into something like that."

"Oh, so, you've seen a vampire like that. I bet you have seen a vampire who's as gorgeous as I am, huh?" I floated beside me and I was impressed. He took the word right out of my head.

"You think so? Believe me, I've met so many that I couldn't remember their names."

"Oh, well. I'd like you to rate me from 1 to 10. 10 would be the highest and 1 would be the lowest. So, what'll it be fair mermaid?"

"I'd say, 0.5." You are totally a hundred, I thought to myself.

"WHAT? Are you serious? It's a rare sight you know Are you sure you won't change your mind?"

"Well, maybe… You're a one." I snorted.

"You're an awful liar. You know that? I can see that you're totally fan girling about me inside."

"Oh please, you are just head over heels about yourself. I don't 'fan girl' on a guy that I just met." I admit he is really observant and handsome too. OH GLOB! I really wish I wouldn't be a bad liar.

Suddenly, a flashing light appeared and footsteps came near.

"Tin? It that you? And… MARSHALL?" It sounded like Fionna.

"Hey wait! You know this tard?" I asked with a huge disbelief in my tone.

"HEY! HEY! HEEEY! Who are you to call me a tard, fish face?"

"Well, she's totally right about you being a tard Marsh." Fionna laughed as she walked closer with the others.

"HEEEY!" He frowned cutely. I wish I could pinch he cheeks. He somewhat, reminds of someone. Oh well.

"We brought food for you Tin." The cat said as she sat beside me.

"Aww.. Thanks."

"So, you know her. Mind to introduce me to this lovely mermaid?" He smirked at me and looked at me seductively. I just rolled my eyes and Fionna did the honor of introducing me to Mr. Barf Brain.

"Marshall Lee, this is Christine Jack, a human. And Christine this is Marshall Lee, the Vampire King and a tard." I giggled.

"HEY! That's not a proper way to introduce someone. Especially the Vampire King." He frowned once again. Arrrgh! WHY ARE YOU SO CUTE?

"Well, then. Let's start again." I suggested. "I'm Christine Jack a fair maiden of the Night O'Sphere. Nice to meet you." I offered my hand politely.

He smirked "I'm Marshall Lee the Vampire King of the Night O'Sphere. A pleasure to meet you fair mermaiden." He took my hand and shook it.

"The pleasure is mine your highness." I played with a British accent and I bowed like a maiden but I was still sitting down.

He smirked and bowed politely while floating in the air. "Oh no, my dear maiden. I must carry the pleasure of meeting such a beautiful young lady such as you. If I may ask, what such beauty is doing in this cave alone?" Well, well, I didn't think that he'd be playing along.

"Oh dear sir, I was cursed by a horrid witch that made takes effect after the sun goes down." I dramatized and stuff then laughed and he laughed as well.

"You're secretly funny little Ms. Fishy."

"You ain't bad yourself little tard king."

"Alright! Cut it you two. Tin, here have some spaghetti. Hope you'll like it." The cat offered me the food.

"Oh. Thanks. By the way, I didn't really get to know you guys. 'Coz I was in a hurry for you know…"

"Oh. Right. I'm Cake. This is Jake the Dog. That's Finn. You've met Mr. Seductive Vampire King, Marshall Lee." She pierced a look onto Marshall Lee like she was gonna claws his face out then she passed out the food to the other and not giving Marshall any.

"Hey, don't I get to eat?" Marshall pouted.

"Under one condition, sing us a song first. A nice song." Cake demanded.

"Uggh. I am hungry but not that hungry." Marshall raised an eye brow.

"Aww… The Vampire King doesn't know how to sing…" I teased.

"I do so! I just don't want to sing." Marshall sounded offended but I still continued.

"Teh. Whatever you say, Vampire King."

"Hah! You just tease me because you are the one who doesn't know how to sing." UH! HOW DARE HE? Ooh! It is on now!

"I do so!"

"Oh yea? Prove it." Marshall smirked as he challenged me. ME! Oohh! He's going down now. I hate being questioned, I think he does so too.
