so i got the idea from rewatching Simon and Marcy the other day on Youtube. it was sped up so the voices were really squeaky, especially little Marceline and i thought "Hey, she sounds really young" and wondered what would happen if she turned into a baby and Finn had to take care of her.

Tantrum


"Good morning, Marcy," Finn yawned and opened his eyes to find he was alone. "Marcy?"

The smell of food cooking in the kitchen made his stomach rumble. After getting dressed the human climbed down to the ladder to the living room to see Marcy playing with BMO. The little robot was running around with the 3 year old right behind him.

BMO ducked under the coffee table and emerged from the other side, Marceline however, bonked her head from not ducking down all the way. She fell back on her butt and began to wail, holding her hands over her forehead.

Swooping into action, Finn scooped her up and began to rock her.

"Sh sh its okay, Marcy," Finn soothed. He managed to pull her hands away to see a bruise already forming. He kissed it several times before putting her down. "There you go, all better!"

BMO peeked out from behind the couch, looking guilty. Coming out, he made his way over.

"Are you okay?" BMO asked.

Marcy looked at him angrily, and pushed the tiny robot over as hard as she could. BMO sat up and looked ready to cry as Marcy hugged Finn's leg.

"Marcy, that wasn't very nice," Finn said, prying her off his leg. "Apologize to BMO."

When the little robot came closer, he was once again shoved away.

"No!" Marcy exclaimed, running into the kitchen.

"Sorry, BMO," Finn said, helping the little robot up.

"It's okay, Finn," he replied. "Babies will be babies."

following after her, Finn and BMO found Marcy hugging Jake, looking at them with a frown.

"I think she's mad at you, Finn," Jake said, laughing, stretching his upper body over to the table and began plating the food. "I went out earlier and bought a couple packs of diapers, she really needed them."

When Finn came closer, Marcy hid behind Jake, and peeked out at him. Finn knelt down and held out his arms.

"Boy, I could really use a hug right now," he said, almost immediately BMO ran over and hugged him. Seeing this, Marcy came out from behind Jake and pushed BMO out of the way before hugging Finn. "Thanks Marcy."

"Want breakfast, Finn," she said, pointing to her open mouth. He laughed, and picked her up.

"Me too, Marcy," he replied. Sitting her down in seat, Finn went and filled her sippy cup with milk.

She wrinkled her nose when he sat it in front of her.

"Want juice!" she said, crossing her arms.

"Juice is for dinner, we drink milk with breakfast," Finn said, picking up the sippy cup, he held it out for her to take. "It's good!"

Marcy turned her head away, then back to the other side when he moved the cup over.

"No milk!" she said, smacking the cup away. It fell to the floor and bounced, causing the lid to come off and milk to go everywhere. "Want juice!"

"Gotta spank her for that," Jake said. Finn looked up at him in surprise as he knelt to grab the cup.

"What?" he asked.

"You gotta spank her," he replied, pointing to the mess. "You have to teach her what she did was bad so she'll learn."

Finn looked over to see Marcy still pouting.

"Yeah, maybe your right," he said.

After it was over, Finn felt guilty, Marcy was curled up on the couch sucking her thumb. He felt her heart hurt at the sight, but; Jake had told him to leave her alone.

"I feel real bad about this, Jake," he said, wiping the wet breakfast dishes.

"Of course, but; its for her own good," he said. "Besides, she won't remember anything once we get her back to her original age."

"Maybe, well I guess its time to go see PB," he said, putting the last of the dishes away. "You ready to go Jake?"

"Sure," Jake replied.

Marcy began to whine as Finn came over. When he tried to pick her up she kept trying to push him away.

"No! No no!" she cried, tears began welling up in her eyes. "Finn mean!"

"Yeah, I guess so," he said, sadly. "Jake, can you carry her?"

On the way to the Candy Kingdom, Marceline kept hiding her face whenever Finn looked at her. He felt really bad about having to spank her, and the thought of her hating him made him feel worse.

"Dude, don't worry about it," Jake said. "By the time we get home later she won't be mad anymore. you'll see."

"I hope so, Jake," he said. "This is really bumming me out."

Princess Bubblegum was finishing her breakfast when Finn and Jake entered.

"Hey guys, so what's- OH MY GLOB!" she exclaimed, bending over to get a better look at Marcy. "What happened to you, Marceline?"

"Up!" she exclaimed, holding out her hands. Bubblegum nervously, and hesitantly, took the squirming 3 year old into her arms. To her surprise, Marcy buried her face into Bubblegum's neck.

"She's still mad Finn smacked her tush," Jake said. "Looks like she really likes you princess."

Bubblegum pried a clump of her hair out of Marcy's mouth.

"Yeah, great," she droned, setting her down on the floor. "What happened to her?"

"We don't know, princess," Finn said. "When I got to her house yesterday she was already like this."

"Hmm, do you think something could have happened to her?" she asked, reaching down to grab Marcy's hand as she tried to wander off. "This sounds like something Magic Man would pull."

"Yeah, except he's Normal Man now," Finn said. "Marcy did mention she found something that could free Simon from his curse. Maybe whatever it is affected her as well."

Bubblegum nodded, letting go of Marcy's hand.

"You two should go to Marceline's house and take a look around," she said. "I'll keep an eye on Marcy till you guys get back."

"Sounds like a plan!" Finn exclaimed, hopefully this would make him feel better. "Let's bounce, Jake."

When the two were out of sight, Bubblegum smiled.

"Okay Marcy, let's-" she looked down to see that the 3 year old had wandered off. "Where'd she go?"

Around the corner, PB could hear someone crying.

"Help! Help! Someone save Crunchy!" peeking around the corner, Bubblegum laughed at the sight of Marcy taking bites out of Crunchy.


"Okay, lets look around for anything suspicious," Finn said. "I'll look around down here, you go upstairs."

"Sure," Jake said, stretching up the stairs.

Finn began by checking under all the furniture, all he found was Schwabl.

"I guess you're pretty lonely, huh?" he asked. Pulling the poodle out from under the couch he picked it up and began petting it. "I completely forgot we left you here alone, you're probably hungry."

Carrying the dog into the kitchen, Finn began digging through the cabinets. Finally, he found a can of wet dog food. Scooping it out onto a plate, he placed it on the floor and smiled s the poodle began to devour it.

"We should probably take you back with us," he said. "At the rate we're going you'll probably starve to death before we fix Marcy."

"Hey Finn, I think I found something," Jake called. Quickly running upstairs, Finn found Jake standing beside a large golden clock. It was ornate with little figures of people and animals and a large gold dragon head resting on top. "Wow, that has got to be it. Lets head back!"

Picking up the clock, the two quickly made their exit, neither taking notice of the large necklace, several dials on its face, resting on the bed.


"No nap!" Marcy cried, fighting against sleep.

PB smiled and continued to rock her back and forth.

"You need your rest," she soothed. "When you wake up, Finn and Jake will be back."

"Finn mean!" she cried, burying her face in PB's neck.

"Sh sh I know, its okay," she whispered. The day had been eventful, to say the least. Marceline was easy enough to keep control of if watched constantly, but; also quick to wander off and get into trouble. Crunchy was still angry, but; PB could deal with that. Now she had to put the energetic 3 year old down for a nap.

Finally, persistence won out, and Marcy drifted off to sleep. Bubblegum carefully sat her down on her bed, before quietly slipping from the room.

Several minutes passed, Marcy rolled over as the window on the far wall opened and the Ice King flew in, his hands crackling with magical energy.

"Honey I'm- hey, she's not here," Ice King lowered his hands. "That's funny, could have sworn I heard her voice in here. Drat! Oh well, I can wait."

Sitting down in a chair facing the door, the Ice King began to giggle to himself and rub his hands together. Eventually, he grew bored, and dozed off. He began to snore like a freight train with a case of the hiccups.

Marcy was woken up by the loud snoring. Rubbing her eyes she looked around the room to see Ice King slumped over in his chair. Climbing out of bed, the 3 year old made her way over. Seeing his long beard, she grabbed it and began to pull.

"Gunter stop pulling daddy's beard," he mumbled. Marcy giggled and continued to pull. Finally, the constant tugging woke him up. "I said stop pulling my- hey, who are you?"

Marcy held out her hands.

"Up!" Ice King picked her up and sat her on his lap. "Me Marcy."

"Really? I know a little girl named Marcy too, she's a vampire," he said. "You know who I am?"

"Santa!" she exclaimed. "Marcy want presents!"

"I ain't Santy Claus!" he exclaimed. "I'm the Ice King! Lord of ice and-"

He was cut off by Marcy grabbing the crown off his head and putting it on.

"Marcy Princess!" she squealed.

Ice King chuckled.

"Yeah, you do look like a cute little princess," he said, as he began tickling her. "I just may have to kidnap you. Heh heh!"

"Grampy funny," she said, hugging him.

"Yeah, I am," he said, an idea popped into his head. Standing up, he carried Marcy over to the open window. "What say we bust out of this joint and go have some fun?"

"Marcy want go outside!" she exclaimed. Ice King put his crown back on and leaped out the window.

"That's the spirit!" he laughed.


"Princess, I think something's wrong here," CB said, as he and Flame Princess rode through the gates on Jake 2. the streets were empty and quiet.

"You're right," she replied. Heating up her hands in case they were attacked. "Stay alert."

From far away they could here voices. Nodding to each other they dismounted from the Fire Wolf and continued on foot. Slipping between the buildings, they carefully made their way towards where the voices were coming from.

"Marcy want red balloon!" a child yelled.

"You heard her snack cake! My little girl wants a red balloon!" another, more familiar voice said. The sound of a loud zap filled the air.

Peeking around the corner, Flame Princess saw a dozen or so frozen candy people frozen solid. The Ice King was walking away with a balloon in his hand.

"Let's go, CB!" she exclaimed, shooting up into the sky like a rocket, Phoebe engulfed herself in flames before shooting down towards the Ice King. "Meteor Shower!"

Ice King turned at the shout to see a giant fireball flying towards him. When he turned, Phoebe saw that he had a little girl with him.

But; it was too late to change her coarse or to lower her temperature.
