-AUTHOR's POV-

-11 YEARS LATER-

Years have pass now, The Land of ooo has changed much now. Now, (YN) is the only remaining human on this land. Rattleballs has told him that him, his parents and the remaining humans that lived on the village were the last remaining humans that survived after the great mushroom war, resulting three major explosions, annihilating almost all humans, and (YN) and his parents were the only ones, alongside the villagers from his home. So, as of right now, Rattleballs tells (YN) that he is the only human left in this land...
.
.
Or so he thought he was.
.
.
Surprisingly, (YN) isn't the only human in this land, for you see, there happens to be another human that lives in the land, and happens to be a girl too. Let us take a view and story of this female human.
.
.
She happens to live a humongous treehouse, where the first very floor is kept nothing but real and actual gold coins and treasure, and on top floor, is where there actual house is. In the living room, we see the female human, wearing a white rabbit theme hat, explode locks blonde hair covering part of her face, and also, she has a best friend, or as she refers to her as her "sister", and this best friend happens to be a cat, not just any ordinary cat, a magical cat, a shifter hybrid, who can shape shift into anything she can. The two grew up together, only thing is the female human was adopted by the magical cat's parents, and raised her as their own daughter as well. Their names are Fionna and Cake.

Fionna and Cake were at the living room playing video games with BMO.

Cake: Left! Left girl!

Fionna: I know! Don't distract me!

Cake: I'm not! You're going the wrong direction.

Fionna: Damn it!

Cake: We gotta defeat this game! No turning back now!

Fionna: I know I know!

The two were struggling one a video game and to pass it. Unfortunately they died on the game and was game over.

Fionna: Aw what?!

Cake: I told you to go left.

Fionna: How was I suppose to know?! That boss kept on spamming the same moves every-time!

Cake: Well you should of know it in the first place.

Fionna: I did, I just-Nrgh! this game is stupid! Ugh I hate it!

With frustration, Fionna stands up and to March away, kicking the chair down and to climb up to her room, leaving Cake and BMO worried...

BMO: Why is Fionna mad?? She's been like this a month ago...are we upsetting her?

Cake: Oh don't worry BMO, it's not you or me...I think I know what's up with her. I'll talk to her.

Before Cake even goes to check on Fionna, she heads to the kitchen and started cooking some food for her
.
.
After cooking, she takes the food and to stretch herself to the room and arrive and to spot Fionna laying on her bed, holding her pillow.

Cake: Hey girl.

Fionna: ...hey.

Cake: I made you some bacon-pancakes, your favorite.

Fionna: Thanks, but I'm not hungry...

Cake puts the food on the counter and sits next to Fionna...

Cake: Fionna, is everything alright?

Fionna: No-I mean yes! I-I mean no-I mean-ugh!

She places the pillow on her face and grunts and turns around...and hugs it again...

Cake: I take that as a no then.

Fionna: I told you I'm fine Cake...

Cake: Really? Cause getting mad over a level one boss isn't alright.

Fionna: ...Uhhh.

Cake: ...Fionna, is this about Flame Prince, isn't it?

Fionna: What?! No! Why-

Cake: Fionna.

Fionna: Mmmm!

Cake: Girl!

Fionna: Okay Okay!! ...yes.

Cake: Figures.

Fionna: ..Cake, where did I even go wrong?

Cake: Well sweetie, you should have thought about the fact that instigating a fight between him and Ice Queen was such a dick thing for you to do.

Fionna: I know! I know it is, and I really really REALLY mess up badly! It's just...*sighs* I just don't know why I find it so hot when Flame Prince beats the crap out of Ice Queen at first...and then I took it too far...

Cake: I don't even know what's bad, the fact you instigated your ex to fight Ice Queen, or the fact you have a fetish of hot boys fighting.

Fionna: Ugh...I'm the worse. I even said sorry to Flame Prince and didn't accept my apology...what an asshole.

Cake: Fionna, sorry won't help for what you did. You even wrote a letter to him to think it was Ice Queen's writing, and wrote personal things against him...you think he's accept you that easily for that?

Fionna: ...N-No...maybe your right Cake, I'm the one that was an asshole...more of a bitch I say.

Cake: Hey, don't say that. Look what you did was wrong, but I know what you're going through, and I'm sorry. Also, it's been a month now since it happen, maybe he's gotten over it, and you should too. And even if you two haven't talked since that day, somehow sooner or later, you two will come around and make up.

Fionna: And be back together??

Cake: I..don't know about that honey.

Fionna: O-Oh....but, if it does happen, like you said, I hope we get to be just friends at least.

Cake: It'll happen, just wait patiently.

Cake pats Fionna on her head as Fionna feels a bit better and gently smiles...

Fionna: Thanks Cake, I needed that.

Cake: Anytime girl, you know Im here for you sister.

Fionna: Yea...can you pass me the food?

Cake: Sure thing.

Cake stretches her arm to grab the plate and handing it over to Fionna as she grabs it and began eating the bacon pancakes...

Fionna: Delicious. Can you get me some syrup?

Cake: Of course-

BMO: Fionna! Cake!

They heard BMO yelling and to see her climb up the stairs...

Fionna: BMO?! What's wrong??

Cake: What is it??

BMO: It's Prince Gumball! He and his kingdom is in danger! The Ice Queen is there!

Cake/Fionna: Ice Queen!!?

Both looked at each other as Fionna puts down the palms her fist...

Fionna: Mentioning her name really pissed me off! I bet kicking her sorry ass will make me feel better!

Cake: That's the spirit girl!

Fionna: Come on cake!

Cake: Right behind ya!

They exit the room and to jump through the window and fall to the ground as cake landed on fours as she grew bigger and Fionna landing on top of Cake, rising her and the two making their way over to the Candy Kingdom.
.
.
As they arrive to the area, they notice the kingdoms surrounded by clouds, a snowstorm happening in the kingdom. Also, the two candy guardians seem to be frozen as well

Fionna: A snowstorm!

Cake: She froze the guardians!? And The candy people are gonna freeze to death with that damn snowstorm!

They rush over to the candy kingdom. As they arrive, they were shock to not only see a snowstorm, but also see ice monsters, such as giant ice worms, ice beasts and ice goblins scary the candy people and trying to eat them.

Fionna: Leave them alone!!

Fionna and Cake rush over to save some Candy People wing chased and trying to get eaten. Fionna leaps and lands a kick towards one of the ice goblins as Cake creates a giant fist to swipe off the ice worms and beasts...but they kept surrounding Cake as she fights them off.

Fionna: Cake!

Cake: Don't worry about me hon! I'll be fine! I'll take care of them, go and stop-

Suddenly, a loud explosion came from the castle, and yet someone floating appears out of the castle, holding Prince Gumball hostage, and it was the Ice Queen.

Ice Queen: Hahaha! Hello Fionna!

Prince Gumball: Fionna! You're here!

Fionna: Prince! Tch, Ice Queen! Let him go!

Ice Queen: Never! This time I won't let you take away my precious prince!

Prince Gumball: You're crazy!

Ice Queen: Yea, crazy for you!

Fionna: You won't get away this time Ice Queen!

Ice Queen: Oh really? I like to see you try!

Ice Queen started blasting her ice powers at Fionna as Fionna started dodging and to run off, she hops on a dumpster and to climb up a building and to run down and leap to another building one by one avoiding Ice Queen's power, she then runs and leaps towards Ice Queen knocking her down and letting Prince Gumball go as Fionna lands on foot and catches Gumball..

Fionna: You alright?

Prince Gumball: Y-Yes! Thank-

Ice Queen: Un-hand my darling, you damn brat!!

Ice Queen continues to blast more of her ice powers at Fionna as she began to run away, taking Gumball with him and take him with his candy people...

Fionna: Stay Here.

Prince Gumball: Okay, be careful!

Fionna goes back running to Ice Queen as Ice Queen began blasting rapid snow balls to Fionna as Fionna started dodging and kicking the snowballs away while running towards her, she tries to land a punch but Ice Queen floats away and continues to blast her magic as Fionna ducks and dodges...
.

.
.

Meanwhile, outside the kingdom, we then see someone approaching out from the woods. This someone was wearing an all black cloak around, covering half his face, wearing heavy metal armor, and holding a huge weapon behind its back. This someone was seeing the Candy Kingdom under attack and hearing loud explosions and the ice storm from Ice Queen's powers. This someone then gave a grin to see what was happening, and to proceed making his way there.
.
.
.
.
.
.
Back to the fight, Fionna kept dodging the ice blasts as she then manage to get close to Ice Queen and to finally land a hit, punching Ice Queen in the face.

Fionna: Ha! Gotcha!

Cake: I'm joining in girl!

Fionna: Nice!

Ice Queen: Nrrgh!! ENOUGH!!!

Ice Queen screams as she causes a wind impact around as she then blasts Cake with her ice powers and freezing her half her body...

Cake: Damn!!

Fionna: Cake!!

Ice Queen: You!!

Fionna turns around and to see Ice Queen using her ice powers to create a big sludge monster and her inside of it controlling it with sharp ice teeth as she controls the ice sludge monster, swinging a hit to her, sending her crashing to the wall.

Cake: Fionna!!

Prince Gumball: Oh no!!

Fionna was hurt from that hit, she tried getting up, but the sludge monster Ice Queen is controlling grabs Fionna by the neck and picks her up...

Ice Queen: I've grew tired of you getting in the way between me and my Prince!

Fionna: H-HRGH!! I-I'm gonna beat you more badly now!

Ice Queen: Oh? And how badly are we talking about? Like how badly you ruined your relationship with that flame Prince?

Fionna: Y-You bitch!!!

Ice Queen: Hey, don't be mad at me, I'm not the one who screwed up a relationship. It's not my fault you can't even handle one either way! Hahahaha!!

Fionna: .!.!.!

Ice Queen: Now! Enough of this!! This is the end!!!

Cake/Gumball: Fionna!!!!
