Fiona and the Prince fidget nervously as Bubblegum looks over scanners connecting the sensors she'd placed on them. Jake and Cake are talking in the lobby. Finn stands by the Princess and gives worried glances at the subjects.
"Umm... Peebs, is this really necessary?"
"Uh-Huh, yeah, sure, great Finn..." She mutters absentmindedly, "Odd, their chemical and genetic make-up are almost identical to yours and mine, save the extra chromosomes... But there is something odd about their molecular structure..."
She scribbles hastily onto a notepad. Then her brow furrows and she gives a long sigh.
"Alright, you can let them out Finn," She switches off the equipment and gathers her notes to retire to her personal study, "Nonsense... What does it all mean...?"
Finn spares no time removing the wires and ushering the two out of the test chamber.
"Yeesh, Finn. This Princess is sure stuck-up..." Fiona dusts her sleeve.
"Hehe, yeah..." Finn chuckles nervously, "Hey, um, lemme, uh... show you my tree house!"
He practically pulls Jake away from his conversation with Cake, "C'mon, Jake!"
"Let's go, Cake! Gumball, you coming?" Fiona looks to her Prince. He looks about sideways.
"...Nah. I'll stick around here. I want to hear the test results."
"Alright," Fiona waves to him, "Careful, Gumball. She might stick a needle in ya."
Finn waits for Fiona in the castle gardens, riding Jake's giant form like a steed.
"So, uh, we going or..." Jake twists his head about to look at Finn, "What's the hold-up?"
"Jake!" Finn exclaims, "You can't just leave a lady! You gotta, gotta let her on your ride, y'know?"
"But she's got her own ride."
"Huh?"
Finn looks at the doorway and sees Fiona mounting on Cake. Cake stretches until she's about Jake's size. Finn is speechless.
"Lead the way, Finn," Fiona says.
Finn sees her teeth, chipped like his own.
"Uh... Yeah..." He flounders a bit, much to Jake's enjoyment, "Let's go, Jake."
"Ooh! Wait, I think I should know the way! I'm gonna beat ya to it!" Cake bounds forth, despite Fiona's calls.
"CAAAKE! Wait! Are you sure- WOOAH!"
"Wha-?!" Finn snaps out of his chagrin, "After 'em Jake!"
The two race along paths that led to the same place and were similar in destination. Finn had never seen any girl move so fast and laugh so hard, not even Marceline. Fiona had never met a boy this wild and straightforward. Marshall tended to confuse her. The two screech to a halt in front of the familiar tree fort. Jake arrives a fraction of a second earlier.
"I knew it!" Cake says triumphantly.
"No way..." Fiona dismounts and walks toward the tree house slowly, "It's just like ours..."
"Huh? No way!" Finn jumps down and walks up next to her, "Y'mean... it's just like with PB's castle... They look that much alike?"
"So that's how you knew it was here!" Jake shrinks down and looks at cake, "It's in the same place!"
"Mm-hmm. Home sweet home!" Cake shrinks and sniffs hungrily, "Do I smell pancakes?!"
"Aw, man..." Finn smacks his forehead, "BMO must be cooking even though we tell him not to touch the stove..."
"BMO?!"
Fiona dashes up to the tree house before Finn can respond. She opens the door and quickly clambers up the staircase leading up to the living/kitchen room. BMO somersaults through the air and hits the handle of the skillet, flipping the pancakes and landing them neatly in a stack on a plate set on the adjacent table. BMO lands on the floor and the skillet subsequently hits BMO on the head.
"Ow."
"BMO!" Fiona scoops up the unsuspecting console and holds it up to eye level, "You're... still you!"
"Huh?" BMO looks over Fiona's shoulder at Finn, Jake and Cake who follow, "Finn, Jake, who are these... girls?"
"Huh?" Fiona looks a little shocked at BMO's remark. Then she looks a little wistfully and puts the little robot down gently on the counter, "Oh, right … Even if you look like BMO... You're still not Aaa's BMO."
BMO looks quizzically at the stranger, "Another BMO? But... Mo said he made BMO unique. Right, Finn and Jake?"
"Achh," Finn and Jake shrug, defeated, "Well, it's something like this..."
…
"Ohh, man..."
Ice King peeks out from his hiding place behind his dirty clothes hamper cautiously. His blank eyes scan about his now ruined pad. Ice Queen was rummaging through his drawer.
"Eugh! You actually wear this?! No!" She tosses his weeks supply of blue tunics to the floor, "After this, I am so doing some shopping at Wizard City..."
No, no, no! How had it all gone so wrong?! The Ice King balled up in the spot where he stood, surrounded by his faithful penguins. They were all looking rather confused at him and the strange new lady in the Ice Kingdom.
"Why did I get stuck with the crazy ugly?! I only wanted Fiona..." Ice King mutters ruefully, "C'mon boys. Think. How do we get her outta here?"
The penguins look at each other and shrug.
"ICE KING!" The monarch flinches at the sound of his new roommate, "Get over here!"
"Y-yes...?" He peers out meekly, then ducks immediately as a bunch of his Finn and Jake BFF photos are tossed over in his direction. The photos flutter to the floor.
"This is a whole lotta junk you got here," She fishes out his friendship locket, "Tell your penguins to get rid of it all."
"WHAT?!" Ice King's temper flares at the sight of his ruined photo collection, "THAT'S IT LADY! GET OOOUUUT! I WILL NOT HAVE ANYONE TOUCH MY FRIENDSHIP COLLECTION!"
His beard wings flap about and he rises into the air. Ice particles swirl about and his power surges. His hands glow white with accumulated power. The Ice Queen, unfazed, rises about in the same manner and her own power surfaces. The two cryo-magicians circle about, the air bristling with snow.
"Is that any way to talk to a queen?" She says icily.
"Hey, I'm King here, lady. The head honcho," Ice King replies leeringly, "And this is my turf."
"Well, let's see then, shall we?" Ice Queen dangles the friendship locket about, "You're awfully sentimental."
Before Ice King could yell, the locket freezes over and shatters in her hand. He only watches speechlessly as the fragments shimmer for a second before falling and the photo floats about like a leaf. Ice Queen freezes at the sight of the photo. Finn and Jake stand posing in front of Princess Bubblegum.
"Who..." She blasts the photo and watches it crinkle away with disgust, "Who is she?! She looks just like Gumball..."
"NOOO!" Ice King howls at the sight of his treasure destroyed. As he squeezed his eyes shut, an ice storm festered and roiled about in the room.
"It can't be..." The Ice Queen is oblivious to the King's despair, for she is lost in a new turmoil of her own, "Gumball's got a fiancee?!"
In the distance, Peppermint Butler glimpses the Ice Kingdom's tallest mountain tower blow it's top, spewing white ice bolts. A shivering cold storm gathers about in the horizon, in the direction of the Ice Kingdom. Alarmed, Peps drops his tray of lump sugar and cream and scurries off to tell the Princess of the impending snowstorm.
