Chapter 1:

Who are these people?

Finn's POV

After Jake and I watched Ice Kings old memories I wondered who Betty was, "Did she die? Is she still alive? She could be a humanoid thing or even a vampire like Marceline. Someone shook me out of my thoughts about Simon (Ice King) and Betty,

"Yo Finn you still here?" asked Jake.

"Yeah I'm still here I was just thinking."

"About what Finn? You have been really spaced out for the last couple of hours and I'm worried about you." said Jake concerned that I was going crazy like the Ice King.

"Don't worry, I'm fine, I'm not going crazy like the Ice King. I'm only 13 remember. I was only thinking about Ice King and that girl Betty in those videos we found about him."

I wonder if Betty is still alive…she could have been turned into a vampire or something, she could even be Ice Queen! No, don't be silly Finn. Ice Queen is only in Ice King's fan fiction as are Prince Gumball, Marshall Lee, Fionna and Cake.

"Hey Jake, I'm going over to see PB." I said. I really wanted to see PB to see if she could figure out if Betty could still be alive and could be the Ice Queen, even though she is in Ice King's fan fictions.

"Ok. I'll go see Lady and give you a lift to the castle." Jake replied.

When I went outside with Jake there was a big flash of light and suddenly two figures appeared. They looked Jake and I, just girl versions of us. One was a human like me and the other was a cat. "Whoa, where are we cake?" asked the human girl.

"I don't know Fionna, but I guess the place is OK. It doesn't look dangerous, plus its looks like our tree house at home." replied the cat, apparently named Cake.

I couldn't believe it I'm not the last human there's another human!?

When I started to walk up to the girl she noticed me.

"Who are you?" the girl asked.

"My names Finn, what's your name?" I'm trying to be nice even though I really want to know how I did not know there was another human.

"My name is Fionna and where are we because I know that we aren't t in AAA.

"You're not in AAA. Welcome to the land of OOO!" I said a little bit too ecstatically

"Um Ok Well how about if you show us around Finn?" Fionna said wanting to see what's in OOO.

"Well, ok, I was on my way to see Princess Bubble gum. She's the princess of the Candy Kingdom." I said since that means Ice Queen will be here too since Fionna and Cake turned up so that means Ice Queen and Marshall Lee will be here to since they are in Ice Kings fan fictions too.

"Princess Bubble gum…don't you mean Prince Gumball?" asked Fionna Oh she must be thinking about him because he's Bubble gums gender swapped version of her.

"Yes and no. No, that it is Prince Gumball because he is the gender swapped version of her, yet he is basically the same person as Bubble gum." I explained.

"Ohhh I get it now. I'm confused as this is the other version of AAA but just gender swapped characters. Like as Jake and Cake are gender swapped of each other's including that Cake is a cat and Jake is a dog of course." Fionna said.

"So let's go and see Princess Bubble gum already." Jake and Cake said at the same time.

"Wow you guys are like the same person; you said the same thing at the same time with the same tone and everything. Wait, Jake, if you're dating Lady Rainicorn, who would Cake be dating then?" I said a bit confused about who Cake would be dating if Jake is dating Lady Rainicorn Cake could be dating a gender swapped version of Lady Rainicorn.

"Well I'm dating Lord Monicormicorn so that must be the gender swapped version of Lady Rainicorn then." Cake said excited to talk about her boyfriend.

"Ok that explains it then, so let's go to the candy kingdom guys!" I said a bit glad to go to the candy kingdom other than just standing here.

"Oohh I know guys let's have a race there, Jake and Finn verse Cake and I. Jake and Cake are allowed to use their stretching powers as that is what it makes it a race" Fionna explained.

"Ok, Ready Set Go!" I yelled as we began to race.

At the candy kingdom

"Ok ok it was a tie even though Cake and I won by an inch" Fionna said Breathless.

"Whoa how are you guys breathless if Jake and I were running" Jake and Cake said at the same time breathless.

"Come on guys let's go inside and see Princess Bubble Gum and let's see what she has to say about this" I said ready to find out how Fionna and Cake turned up in OOO because they were in AAA for one second then in OOO the next.

Inside the Candy Castle

"Hey PB what's upppp…?" I said a bit confused cause I saw a candy prince who looks exactly like PB except he's a guy.

"Oh hey Finn I bet you're confused about this but this Prince Gumball and he likes science like me" PB said enthusiastically.

"Hey Fionna so you found your way here too?" said Prince Gumball discovering that it wasn't only him that appeared in OOO.

Marceline's POV

As I was sitting well floating on my couch playing my axe bass suddenly a bright light appeared and a vampire appeared that looked like me but was a guy that looked confused.

I noticed that he had an axe bass like me but had a skull at the end of it and looked like an actual axe that just had strings on it. I had heard of that happening from my dad but it last happened a few hundred years ago when I was still in the nightosphere. Just looking at the other vampire I realized that I had seen him before way before I became a vampire.

AN:

Hope you guys enjoyed it and that I left it on a cliff-hanger who is the other Vampire?

How does Marceline know him?!

But remember im just an amateur at fan fiction and this is my first story so be nice please!

The next chapter should be up soon as soon as I get ideas

Thanks
