Woah! Around 100 visits in the first 24 hours of the first chapter being up? I feel loved! (No, I don't care if that's normal, I still feel loved.) A super special thank you to my first three reviewers: Romanceismythang, Chozowarrior, and ILoveAdventureTime! You guys get cyberspace snicker doodles!

Just to let you guys know, I plan to change narrators quite a bit. Back-to-back chapters of the same POV will be rare until I get a feel for the direction I want to focus this story. I will try to write the separate characters differently through word-choice and the like, but sets of gender-swapped characters (e.g. Finn and Fionna) should sound fairly similar. Also, my use of Adventure Time phrases like "oh my glob" will become more limited because it feels odd to write and looks weird in text, in my opinion. I hope that doesn't annoy you guys.

DISCLAIMER: I own nothing. I'm not Pendleton Ward. Hopefully you knew that already…

Fionna's POV

How did this kid know my name? Where the lump was I, anyway? One moment I was waiting outside the tree house for Cake and the next there was a sword coming at me out of nowhere! After defecting it I found myself in a room that looked like it had had a touch of Gumball's interior design. There were test tubes and pink fluff everywhere you looked. It was a familiar scene, but the faces were all new to me.

The boy under my knee was freaking me out a little. He looked like he had raided my closet and chopped the ears off my hat. What was he copy-catting my look for? Then there was the chick with long pink hair. Did Gumball have a sister that he never told me about? And the creepy old dude in the corner could have been Ice Queen's crumbly old dad. Cake would have choked on a hairball if she could have seen these guys.

Suddenly I was surrounded by a blanket of yellow. "Oof! Let me go! What kind of sick trap is this?" The net was fuzzy. Why would these freaks make a fuzzy net? What did that accomplish? A second later I was seated a chair and there was a dog in front of me shrinking to normal size.

Okay, so where did that leave me? A kid who wore my clothes, kind of, long lost relatives of Prince Gumball and Ice Queen, and a dog with Cake's stretchy powers. I glared at each person in turn, feeling my crystal sword still in my hand.

"Okay, forget the 'who are you' thing. What is this place, and where's Cake?"

Ice Grandpa made a giddy little girl noise and I could hear him mumbling, "They're real… They're real…"

Miss Pretty in Pink stepped forward with a royal flourish of her hands. She was getting more Gumball-y every second. "Fionna the Human, welcome to the Land of Ooo! I am Princess Bubblegum. These are the heroes Finn the Human and Jake the Dog. And that," she dropped the elegance in her voice. "is the Ice King."

Okay, she had my attention. "What's Ooo? What happened to Aaa? And where's Cake?"

Princess Bubblegum pointed at a giant circle thing with a glowing green orb hovering in the middle. "Cake and Aaa are in there. It's a dimensional rift. Ooo is a lot like Aaa, but the two are entirely different dimensions. Ice King literally imagined your whole world into existence when he wrote fanfiction stories about Finn and Jake. Please don't ask me how that works. The science is not absolute, and I don't believe you would want to listen to me lecture you on the workings on inter-dimensional creation and control. That would take several weeks, and even then you may miss something."

Finn the Human coughed. "PBubs, here, I've got this." He stepped forward to my side and stared up and off into the distance.

"Um... Finn-"

"Shhhhh…" he cut me off. "I will explain… through interpretive dance." He moved back and started to make funky motions with his arms that made absolutely no sense.

"Finn, bro, you're banananoos." Jake the Dog interrupted. "All she needs to know is that she's a figment of Ice King's imagination, and that she's really just the girl version of you. But that's okay with us, because everyone is welcome in the Candy Kingdom, even book characters! Unless they're evil sorcerers. We kick those dudes out on their buns."

The Ice King piped up, crawling toward me on his hands and… beard? "Jake, you forgot the important part: we're getting married! Fionna the Ice Queen. Doesn't that sound pretty?" he asked me.

"Ew, are you nuts? I'm not marrying anyone, you old creep!" I jumped out of my chair and pulled out my crystal sword. "Aaa is a real place, and I'm not some freaky book character! I'm Now let me go back home!"

Just then the whole room flashed bright white and I felt someone grab my arms and lift me into the air. I fought wildly against my attacker, flailing my sword blindly. Whoever it was yelled in my ear, "Whoa, whoa, Fionna! Chill! You're going to knock us out of the air!" When I could see again I found myself face to face to Marshall Lee about ten feet above the floor. "Are you okay?" he asked. "I heard you scream through this freakish green thing floating outside your place."

Below us, Bubblegum groaned. "A demon's touch... Of course, the door opens both ways. We might need Marceline after all…"

A Goth girl with mega-long black hair and gray skin floated in the shattered window next to us. "Did someone say my name?"

AN:

Sorry. I know this was a cheesy, poorly written chapter. I had writer's block and I needed to get through it so we could get onto the rest of the story and begin introducing the other characters, start forming pairings and stuff. Review please! Plotline input is welcome, and I will give credit if I decide to use your idea, but it's nothing personal if I decide it doesn't fit with the idea in my head. Thank you!
