BMO looks about the odd scene at the dinner table. Finn and Jake sat opposite to Fiona and Cake. Fiona and Cake... BMO scrutinizes at the two strangers at the table. It was rare for girls to be invited to the table, and it was definitely weird that Jake was so okay with a cat. He said she was magic like she was. Fiona and Finn were also interesting. They ate in the same rough fashion and they registered as "twins" when BMO tried out the new scope scanner gadget Bubblegum had installed for him. For Jake and Cake, it read "opposites".

"Ahh," Jake leans back, content, "Nothing beats breakfast for dinner."

"Mm, Nope!" Cake pats her furry stomach, "Well, maybe 'cept for my sizzlin' salsa combo."

"Salsa? Man, I'd love some!" Jake jumps up.

"JAKE! You just ate!" Finn scolds. He was pretty full.

"Aw, don't worry, there's still plenty o' room in the ol' basket," Jake's stomach expands to show his point, "Now, how about that salsa?"

"Let's get to it!"

Jake and Cake begin quibbling in the kitchen over ingredients. Finn and Fiona are left at the table with BMO. Finn looks up from his bacon pancakes to see Fiona eating. She looks up at the feeling of being watched and their gaze locks again. BMO squirms a bit nervously.

"This is really weird."

…

"Bonnie?!"

Marceline bursts in through the candy doors and shouts for the princess at the top of her lungs. The banana guards notice a strange guy following her in. He looks kinda like her, but in a parallel universe kind of way.

"Uh, so who are we looking for exactly?" Asks Marshall Lee apprehensively.

"Bonnibel. AKA Princess Bubblegum. She'll figure out this jazz."

"Princess, huh? You know, where I come from, Princes were the real guys with power."

"Marceline!" PB appears, stack of papers in hand, "What are you doing, jacking up my peeps?!"

"Oh, there you are!" Marceline flies up to her, "Listen, I've got a huge problem. There's this guy who's-"

"Your possible equal and twin? Yeah, I know," The princess interrupts, "Me and Finn already met ours. I'm still trying some calculations to explain this possible phenomena."

"No! He's not my-"

"Sorry, like I said, I'm busy!" The princess leaves. Marceline throws her hands in the air.

"Ugh! Why does she always have to be like that?!"

"Hm. She sure reminds me of someone I know..." Marshall rubs his chin.

"Marshall? Is that you?"

The two vampires turn to the voice. Prince Gumball stands nonchalantly, in a bathrobe, under a corridor threshold.

"Gumball?" Marshall Lee's jaw drops, "What are you... What are you wearing?"

"Huh? Oh," The Prince chuckles sheepishly, "I just took a bath. Did not expect another familiar face here."

"Who's he?" Marceline looks queerly at the gummy Prince.

"Prince Gumball. AKA his snooty highness," Marshall smirks, "Seems there' others that wound up in this place."

"Others...?" Marceline could not believe it. If this was really Gumball and she's right about her gut feeling on Marshall, then...

"Oh, Fiona and Cake were here just now with their look-alikes. You oughta tell her you're here."

Fiona? Cake? Now Marceline had to tell the Princess. But just as she's about to burst into Bonnibel's lab, Marshall yanks her towards the doors.

"Marshall! Let me-"

"Come one I can't stand the air in this snobbish place."

Despite her protests, Marshall drags her out of the castle. He mockingly bows to Gumball before leaving. Gumball scratches his head, confused.

Peppermint butler suddenly bursts in, arms flailing.

"Where's the Princess?! We must prepare for a national snowstorm!"

Snowstorm? Gumball suddenly remembers. Amid all the head-reeling revelations, he'd forgotten that if all his comrades and rivals were here, then she must be here as well. His crazy stalker, Ice Queen. And if this world was really such a reciprocate, then there is a male version of her probably as nutty and powerful as she.

"She's in the lab," Gumball stops the butler for a bit more. "Say, is there an atomic heat glazzmoglobber here?"

"Why, yes," The butler looks stunned at this stranger whom the princess had called her guest, "But it's locked with the Princess' code, I'm afraid."

The butler continues on his way, glad to be away from that look-alike of the Princess. He didn't like it. He'd gotten a whiff of the scent lingering on these doppelgangers of the Princess, Finn and Jake. They smelled of magic, the kind of Magic so great and dangerous Belle Noche had to be created to destroy it.

"Princess?" He pushes aside his thoughts along with the door. It is dark in the lab, save for green luminescence where Bubblegum was crouched over her work.

"Hm? Yeah, Peps?" She doesn't turn around.

"Princess! There is trouble approaching from the Ice Kingdom! I've seen the clouds! We must tell the citizens to lock down!"

"Oh no..." The Princess groans, but not at the news.

...

The green luminescence lamp fizzles as the electricity is suddenly sapped and all of the kingdom goes into darkness. The night scares several of the citizens and they explode. Some get angry about being interrupted in the middle of their business. They bump into each other blindly shrieking as a sudden chill settles from the sky. Powders of fine snow rain down like sugar as voluminous clouds gather in the night. Blue lightning streaks across, growing in intensity. The Kingdom is not the only area affected. Hail as big as a fist is raining down in the Slime and Fire kingdoms. The Treehouse sits at the edge of what seems to be the ice-storm of the century.

"Whoa, look at those clouds..." Finn puts down his ice cream to gaze at the clouds outside, "We better bundle up, guys."

"Huh?" Fiona walks up next to him, "Storm? Y'know, back in Aaa, this stuff was usually the work of the Ice Queen."

"Ice Queen?" The pang of familiarity hits Jake again, "I've heard of her somewhere..."

"Geez, she sounds even more bummin' out than Ice King. Jake we better check it out."

"Hmm..." Jake doesn't hear Finn as he puts on his thinking cap.

"JAKE!"

"Whoa! Okay, okay..." The two brothers leap out of the treehouse together. Finn lands on Jake as he morphs into a car.

"Uh... You guys hold the fort here. We'll be back before you know it!"

Fiona and Cake watch as the two drive away.

"I can do that..." says Cake sulkily, "Hmph. Them boys are such showoffs!"

"Yeah... I mean, we can help, right? They don't know what their jumping into if they meet the Ice Queen..."

"Oh, don't you start makin' excuses!" Cake digs at Fiona's arm, "YOU like him!"

"What?! No! I... We hardly know each other!" Fiona blushes.

"You're practically twins!" Cake flails her arms in emphasis, "Ohh, what do you think is gonna happen if Marshall and the Prince find out? Hm?"

Fiona looks exasperatedly at Cake's smug face and sighs.

"BMO, you can take things from here. Let's go already."

…

"Oop, there they go."

Marshall, after practically lugging Marceline to the treehouse, arrives just in time to see Fiona ride a giant Cake off in the direction of the Ice mountains. He finally releases his grip on Marceline.

"Ugh! What is wrong with you? Uhh! Are you deaf?!" She spat at him angrily, rubbing her arm.

"Hey," Marshall says, ignoring her fury, "What say we crash in there until they come back?"

"Who, Finn and Jake? Oh..." Marceline remembers, "You mean Fiona and Cake."

"Well, yeah. I mean, this is their place."

"No, it's not," Marceline looks at the old house, "It's Finn and Jake's. I gave it to them."

"Who're these two? They seem like a pretty big deal," Marshall casually opens the door and lets himself in, much to Marceline's ire.

"Ughhh, sheesh," She palm-smacks her face. He was the same character she'd created from then, at Ice King's story-telling. No wonder he was so annoying, she'd made him that way.

She turns around to gaze at the worsening weather. As snow falls gently, she is suddenly reminded of the Ice King's castle. And what she'd found in the lowest levels while snooping around invisible.

"Marshall?" She calls out.

"Mmm?" Marshall sticks his head out, his mouth full of jelly donuts. BMO is viciously trying to kick him out but to no avail.

"We're going to the Ice Kingdom."
