The Land of OOO
(In the land of AAA)
Fionna was just getting to ready to lay down and go to sleep when all of a sudden Cake ran up the ladder and jumped into her drawer falling fast asleep. Fionna looked over at her friend before continuing to her own bed to sleep. As soon as her head hit the pillow she was out. It had been a long day of adventuring for the two of them. But little did they know the Ice Queen was waiting outside the house for them to go to sleep so she could have the best chances of casting her spell without being interrupted.
She slowly flew into the house careful not to make a sound as she passed a sleeping B-MO. Ice Queen flew up the stairs to the bedroom shared by Fionna and Cake. She floated over Fionna's bed and pulled a potion out of her dress pocket. She tipped the bottle letting a single drop fall onto the head of the adventurer. Before the girl could wake up and catch her the Queen flew out of the window to escape the tree house.
The drop of the potion began to glow a pale blue, filling the room with a soft light. After a short time the light disappeared from the room. Fionna and Cake continued to sleep through the night without knowing what the Ice Queen had done.
(In the land of OOO)
In a very distant land Finn and Jake were also in the process of getting ready for bed in their tree house. "Dude that dungeon was awesome! We should go back tomorrow and continue to explore." Finn stated to his brother.
"If we have time after we help Bubblegum with that thing she wanted us to do." Jake said crawling into his bed.
"Oh yeah, that thing." Finn said crawling into his blankets. He laid his head down onto his pillow and slowly fell asleep. After a while the Ice King flew up to their window and leaned against the glass checking to see if they were asleep. Once he was sure they were out, he slowly pushed against the window to open it. Flying into the window he made his way over to Finn's bed holding up a small vial that contained a blue liquid. He poured a drop onto the human's head before stuffing the potion into his beard and flying away.
Finn's head began to glow, filling the room with a pale blue light. Finn opened his eyes slightly seeing the light. "Go back to sleep B-MO." he said sleepily before closing his eyes again as the light faded.
(Parallel between the two)
In the middle of the night both adventurers sleep was invaded by weird dreams and a bright blue light. Finn and Fionna woke up with a start glancing around the room. They looked over to the usual place where there friends sleep. Seeing the familiar lump of blankets in the drawer they relaxed again from what they thought was just a dream.
(In OOO)
When Fionna woke up the next morning she flipped out of bed and landed at the end of her bed. She looked over and saw that the drawer was empty. "Huh, Cake must be up already" She thought out loud to herself. She jumped down the ladder into the kitchen, and looked around. She noticed B-MO in the room and walked over and tapped on the device. "Hey B-MO have you seen-" Fionna started to ask but was cut off by B-MO screaming and running off after he turned around to see Fionna. "Huh, wonder what's wrong with him?" She walked down to the front door of the tree house and stepped outside. "Cake probably went to Lord M's house. I'll leave her a note to tell her to meet me at the Candy Kingdom when she gets back." The girl reached into her bag and pulled out a pen and notebook paper, scribbling down a quick note.
'Hey I headed over to the Candy Kingdom. Meet me there.' The note read.
And with that she took off to see Prince Gumball. When she reached the kingdom she ran up to the palace and nodded to the banana guards before going through the front doors. When she was passed the guards they exchanged glances.
"Must be trying out a new look." One of the guards said to the other shrugging.
Fionna made her way up to Prince Gumball's room, knocking on the door when she reached it. "Come in" said a voice through the door. Fionna pushed opened the door to see a pink girl sitting at a desk. Before the girl could turn around Fionna drew her sword and pointed it at her.
"WHO ARE YOU?" yelled Fionna at the pink girl.
The lady turned around, "I'm Princess Bubblegum, who are you?" She stated calmly. After years of being a princesses she knew how to handle these kinds of situations.
"Princess?" Fionna whispered to herself before shaking her head, "WHAT HAVE YOU DONE WITH PRINCE GUMBALL?"
"Prince Gumball?" Bubblegum questioned the girl. "I don't know what you're talking about but maybe you should put the sword down and we can talk about this."
"WHAT DO YOU MEAN YOU DON'T KNOW WHAT I'M TALKING ABOUT?" Fionna stopped for a second before thinking about everything. She then started to chuckle. Bubblegum looked around to try and find the source of what was causing the girls laughter. "I get it. This is a prank and I know just who is behind it. Oh I'm gonna bop Marshal Lee so hard. Hey great job acting but you don't have to pretend anymore. Just if Cake comes by tell her I went over to Marshal Lee's house." She turned around and walked out of the room laughing.
Bubblegum sat there staring at the door. "Gumball? Cake? Marshal Lee?" She thought aloud to herself.
After a short walk Fionna arrived at the opening of the small cave. She walked up to the door and heard the familiar sound of a bass. Fionna knocked on the door and the playing stopped. A couple of seconds later the door opened.
"Hey Fi-" The girl who opened the door stopped suddenly when she saw that it wasn't the small boy at the door. The girl grabbed the adventurers arm and dragged her inside. Before Fionna could get a word in she was sitting on the couch. "Finn did Bonnie experiment on you again? I thought I told her to stop doing this. I mean I have to say though you don't look bad as a girl." the girl chuckled.
"Who are you? And who is Finn and Bonnie?" Fionna asked.
"Did she erase your memories too? Well you're Finn and Bonnibell must have experimented on you to make you a girl. And it's me Marceline, Marcy, Vampire queen. Come on stop joking around."
"My name is Fionna and no one turned me into a girl. Iv'e always been one,"Fionna stated, "Plus Vampire Queen? Since when is he married." Fionna thought aloud.
"Married? No one's married." Marcy replied quite confused at this point.
"Then how are you the vampire queen?"
"Because I killed the vampire king before he bit me." Marcy explained.
"YOU KILLED MARSHAL LEE THE VAMPIRE KING?" Fionna jumped up off the couch screaming as tears started to pour out of her eyes.
"Hey calm down. I don't know who this Marshal Lee is but he can't be the vampire king because I'm the last vampire in all of OOO." Marcy said trying to get the girl to stop crying.
"Wait what do you mean OOO?"
"I mean OOO. You know the place we live in."
Fionna eyes widened. "This isn't AAA?"
