Chapter 1: Prologue

The winds had always howled into the night, and the moon brightened the earth in its nocturnal presence. As night embraces the land of Ooo like a cloak. The tree fort was all quiet, not even a single sound was heard. Our heroes Almost everyone in the lands were asleep, ever since the birth of the children, Jake had finally moved in with Lady to take care of the pups. Finn, BMO, and NEPTR were the only ones currently residing in the tree fort. Finn was standing, looking out the window to gaze at the stars and the full moon up in the sky.

Finn sighed, an uncomfortable thought kept haunting his mind. It was a question that couldn't be answered by him or anyone else.

'Am I the last human?' He thought. The situation weighed heavily upon him. Day after day it grew more inside him rather than vanish.

Finn had slumped on his bed. He didn't even bother to move a muscle. He was in the soul searching moment. After an hour Finn finally fell asleep. Although it wasn't easy for him.

Land of Aaa:

The situation was much similar to what Finn had experienced. The heroine was looking at a photo of her and her adoptive family. The day that Cake decided to live with Monochromicorn took its grasp on her mind. She missed her companion and adventuring partner. Fionna had then heard a phone ringing. She ran over to pick it up on the other line was Prince Gumball.

"Hello?" She asked.

"Ah Fionna, good to hear from you, I have discovered something important I'd like to show you. Please come by the castle as soon as you can." He said excitedly. From the sound of it, he was seriously eager to show her what he found. What was it that he found that made him like this but more than usual?

"I'll be right over." And with that Fionna hung up. She was now eager to find out what Gumball was talking about. She grabbed her crystal sword and backpack and ventured into the Candy Kingdom. As she arrived, Peppermint Maid had escorted her to Gumball's lab. When she entered, she saw Gumball pacing back and forth.

"Fionna I'm glad to see you." Gumball said.

"Hey, what's going on? What's got you so excited all of a sudden?" She asked with a smile on her face.

"I found a pool, but its not an ordinary pool. You see, it's a doorway to another dimension. A candy person stumbled upon it and saw this other world." He replies.

"But what does this mean exactly?"

"From their report, there was another human like you. I thought it would be interesting if you had the chance to see him."

She was overflowing with joy. Another human actually existed! Now the lifelong question was finally answered. She wasn't alone.

"Really! Wow that's great! Where can I find it?!"

Here's a map that shows exactly where it is. But do be careful Fionna, the road may be..."

Fionna had disappeared from the lab before he got to finish, she read the map and ran to the destination.

Back in Ooo:

Finn woke up after sleeping for thirty five minutes, he groaned in annoyance that he couldn't sleep. He decided to go outside. From there he finds a pool with a sparkly, glowing appearance. It looked beautiful.

Finn moved toward the pool and looked at his reflection. But it wasn't his, it was the image of a female instead.

'It wouldn't hurt to maybe swim in it for a while.' He thought. Finn jumped in it and was transported to Aaa.

Oblivious to the known fact, Finn had gotten out of the pool and began to walk toward the Ice Kingdom.

'I should check if Ice King kidnapped anyone overnight.' He thought. The Ice King had always kidnapped princesses. He usually did either the 'sweep her off her feet' or the 'romantic night' bit with the princesses. Finn would usually check if anyone was there.

As he arrived at the Ice Kingdom, Finn had sneaked his way into the castle. He saw penguins just waddling around, not paying any attention, but what Finn found was odd. One was that nobody was in the cell and all penguins had a pretty bow on their heads.

Looking around he sees a pink book titled 'Adventure Time with Finn and Jake'. The front image looked like a woman and Finn kissing. This made Finn uncomfortable. He couldn't stomach this. With enough willpower, he decides to open the book. What he saw made him blush madly. The writing, the drawn pictures it all made him blush. This was an erotic fanfiction. It showed how Finn and Ice Queen were having sexual intercourses throughout the whole story. It all had the Ice Queen and Finn touching each others bodies and the dialogue was truly intimate.

He couldn't deny the fact that this was giving him a boner. His mind was going haywire. He actually took the scenes into consideration. Maybe he wanted to 'do things' with the Ice Queen.

Before he could drop and close the book, his body was quickly encased in ice. A silhouette made its way to him and took Finn into a certain room.

Back to Fionna:

Fionna had found the pool at last, at the moment she stopped, a small letter had slipped right out of the map. It had Prince Gumball's handwriting.

Fionna:

If you are reading this, I want to give you more information about the pool. I anticipated that you would run off to the pool all by yourself. If someone sees a reflection of themselves in the pool with a different gender, it is what your counterpart would look like. If the pool shines red, it indicates that your double would be in the same universe as you.

Signed: Prince Gumball

Fionna then looked at the pool closely. She did see the reflection of a boy. The search was narrowed down for her. She can now identify what her counterpart looks like. Suddenly in a mystical kind of way the pool turned red.

It is revealed that her male counterpart was here in the land of Aaa. But the question was where?
