Author's Notes: Hey guys! Time for another one shot! This one has a really cool idea in it. So basically, I've had the idea of Star and Marco babysitting for a while now, but after I saw a tumblr post on svtfoeheadcanons blog talking about how there should be an episode of them babysitting the Buff Frog's tadpoles, I couldn't resist doing a one shot of it. This takes place the day right after the events of Storm the Castle.

Sadly, I am a little upset about this because I think it should've been longer and there are so many opportunities to do stuff in this idea. I even might consider writing another one shot stemming off of this.

Credit for the idea goes to whoever first posted the idea to svtfoeheadcanons' blog on tumblr. I loved the idea the second I saw it.

Well anyways, enjoy the fic!

It was the day after Ludo's castle had been blown up and the wand had been cleaved, that Star and the Diaz family were finally returning back to Earth. In apology for giving the Diaz's such a hard time, the king and queen offered to let them stay at their castle for the night in the royal guest bedrooms.

Mr. and Mrs. Diaz excitedly stepped out of the portal and rushed towards their home. The guest bedrooms at the castle were nice and all but nothing could replace the feeling of living in their nice and cozy home. They quickly opened the door and hurried to the kitchen, wanting to start cooking breakfast as soon as possible.

Not long after them, Marco Diaz stepped out of the portal and inhaled the sweet smell of fresh air.

"Ahhh!" he let out, satisfied. "Home sweet home!"

He took a step towards the house, intent on helping his parents with the cooking, until a figure bounded out of the portal and tackled him to the ground into a massive hug.

"Whoa!" he yelped as he lost his balance fell to the soft ground. There was only one person he knew that acted like this.

Marco groaned and shifted himself to where he was facing his attacker. It was Star Butterfly, his best friend and princess of Mewni.

"Star! Not again!" he complained with a secret smile on his face. From time to time, Star would ambush him into a hug and he would always try to act annoyed but actually loved getting her hugs.

Star did not reply to his comment as she tightened her hug on him. Marco looked at Star questionably. She would usually be excited and giggling when she hugged him but right now, she was silent and seemed somewhat... nervous. Picking up on this, he sat up and placed a hand on her shoulder.

"Uh Star? Are you okay?" he asked, confused. He couldn't really think of a reason on why she would be upset.

Star quietly pulled away from her hug and sat next to him while looking at the ground dejectedly.

"Marco," she started softly. "I'm really sorry I acted like a jerk yesterday. I-I wanted to apologize sooner, but I was kind of um-" she paused for a moment and fiddled with her hands "-nervous."

Marco's eyes widened in surprise as he looked at her. He had already forgiven her about their argument they had yesterday and had even totally forgotten about it. He didn't think that it would still be on Star's mind after all the events that had occurred.

His expression became soft as he placed his arm around Star. "It's ok really Star-" he started.

"No it's not!" she looked up at him with sad puppy eyes. "I'm really sorry I obsessed over a sandwich Marco. I just... wanted you to try a bite. I knew you would like it."

Marco smiled softly and patted her head. Star looked at him with wonder at the gesture.

"It's ok Star, I forgive you," he told her. In truth, he had forgiven her a long time ago.

"R-really?!" she gasped. "But-but even after I said that-"

"We're friends 'till the end," he spoke calmly. "And that's all that matters."

Star started to tear up at the gesture and tackled Marco into another hug pushing him back onto the ground.

"AWW YOUR SO SWEET MARCO!" she cried out happily as she nuzzled his face.

"Star!" Marco laughed as he tried to brush the blonde hair off his face as Star continued to cry out compliments about him.

Star pulled her head away from him but kept her arms around him, her usual bright smile gracing her face as she looked down at the face of her best friend.

"Thanks Marco for being a great friend!" she chattered. "I have a present for you to make up for what I said yesterday!"

"Huh?" Marco said. Star took her arms off him and sat up to reach for something in her purse.

A present? What could she have possibly-OH GOD! Marco stared at her in horror as she pulled out the sandwich from yesterday. It smelled horrible and flies were circling around it, an indication that it probably was not suitable to eat anymore.

"O-oh! You uh, kept the sandwich," Marco spoke weakly as he tried his best not to throw up at the sight of it.

Star gave him a wide smile and raised the sandwich into the air. "Yep! I thought that it would be a good idea to let you have the last piece of this sandwich! I know you're going to love this once you take a bite!"

"But uh Star," he reasoned with her. "That sandwich doesn't look very... safe to eat."

Star shook her head in protest. "Pffft! It's perfectly safe! Now open wide!" she said as she brought the sandwich closer and closer to his mouth.

Marco stared in horror as the sandwich came closer and closer to him, smelling worse the closer it was. "Uh, It's okay Star!" he panicked. "I'm not that hungry!"

He struggled to get out from underneath Star but she quickly noticed this an engulfed him into a hug with her on top, her free arm wrapping around his neck as she brought her face closer to his.

"You can't fool me Marco! You haven't had breakfast yet! Of course you're hungry! Now stop resisting and say ahhh!" Star said determined as she moved her face and aimed the sandwich towards Marco's mouth.

"WAIT! NO STAR!" he screamed. "I DON'T WANT TO EAT THAT SANDWICH!"

Marco used his left arm and grabbed Star's arm before the sandwich could reach his mouth. Marco closed his eyes and sighed in relief but as he opened them, he saw Star still smiling with the sandwich now transferred to her other arm and was now bringing it closer to him.

Marco's fear of the sandwich drove him to react quickly and grasp Star's other arm before she could make him eat it. Star frowned and started to struggle with Marco as he gripped both her arms, determination etched on his face not to eat that disgusting sandwich.

"Marco!" Star pouted, still gripping the sandwich but unable to bring it any closer to his mouth. "Stop resisting! I'm going to make sure you eat this sandwich!"

In reaction, Marco quickly rolled over, flipping Star to where now he was now the one on top holding both her arms to the ground and she was below him still grasping onto the sandwich.

He smiled victoriously. "Ha! I guess I don't have to ea..t..." Marco's words died out as he realized the position he was in. His face was barely hovering over Star's face and all it would take was him to lean down a little so that he would be kissing her. He looked at Star's eyes and realized that they were very distracting. They were a beautiful sky blue that seemed to hypnotize Marco.

"Marco, why are you staring at me like that?" Star asked snapping him back to reality.

A blush crept on his cheeks and he removed his grip on her arms as he stammered apologizes.

"L-looking at you like what?! I w-wasn't looking into your eyes! I-I-I was just-" he started.

Quick as a flash, Star rolled him over to where they were back in the position where he was lying down from under her but this time, both his arms under her knees as she held the sandwich up proudly.

"Ha! Got you now Marco!" she shouted victoriously as she positioned the sandwich over Marco (who was now only blushing slightly) while he struggled to free his arms in futile. "Now taste the deliciousness of DEFEAT!"

"Uh, am I interrupting something?" a heavy, Russian accent came from their right side.

Marco and Star turned their heads to see Buff Frog standing there with a confused look on his face as he held a water fountain strapped on his back.

Star quickly forgot about the sandwich and stood up and assumed her battle stance. Even though she didn't have her wand, she could still kick some major butt. Marco quickly followed her lead and took his karate stance... after noticing the sandwich was unguarded and kicking it into a nearby bush.

"What are you doing here?" Star demanded. Even though he helped her get Marco back, she still didn't trust him. "I'll blast you if you don't answer!"

"Wait! Wait!" Buff Frog held his arms up in defense. He quickly slid the water fountain off his back. "I mean you no harm! I just need a favor!"

"A... favor?" Marco asked, unsure.

Buff Frog nodded as he pointed to the water fountain filled with dozens of tadpoles. "Since the castle blew up, I need to find somewhere to keep my children safe. Therefore, Ive decided to find a permanent home for my babies."

"Whoa Whoa WHOA!" Marco shook his head in disbelief. "Babies?! You're a father?!"

Buff Frog nodded solemnly. "Ludo has given me these babies. They are my children."

Marco looked at the water fountain then back at Buff Frog. "Ludo... gave you... babies?"

The giant frog nodded. "Yes, that is correct."

Marco was silent for a moment. "...Excuse me for a second." He left the scene and walked inside the house momentarily. A scream so loud Buff Frog and Star had to cover their ears rang through the Diaz family residence. From inside the house, Marco was banging his head on the table and chugging down gallons of holy water as he tried to forget the horror he had just imagined.

"NOOOOO GOD! NO GOD PLEASE NO! NOO! NOOO! NOOOOOOOOOOOOOOOOOOO!" he screamed.

Marco walked back outside looking like he had just seen a ghost. "I'm fine now," he croaked out.

"Um, anyways," Buff Frog continued. "I will need you two to take care of my children while I find a suitable home."

Marco looked flabbergasted at the request. "What?! You can't just expect us to take care of your... children (*shudder*). We're not qualified to take care of some frogs!"

Star bit her lip and lowered her weapon. She had been thinking about the request the entire time. It may be a trap but she couldn't discount the fact that he had helped her save Marco. "I guess it wouldn't be too much of a problem to help, right Marco?" she said.

Marco looked at Star wide eyed. "Star! You're really going through with this?! What are we supposed to do with all these tadpoles?!" he reasoned.

Star smiled sheepishly. "Well he did help me save you and um, we can look something up online." she brought her hands together and gave him her puppy dog eyes. "Pleeeeaassseeee?" she begged.

Marco stared at her for a second before letting out a sigh. "...Fine," he relented as Star gave him a smile and turned to face Buff Frog.

"It's a deal!" she exclaimed nodding her head and jumping up and down.

Buff Frog gave a grateful smile as he picked up the water fountain and dumped it in front of the two teens. Star walked up to the waterfall and chuckled seeing the little tadpoles.

"Aww, they're so cute!" she squealed as she leaned over to watch the little tadpoles swim around. "Marco come look!"

Marco had an unsure face as he walked over next to Star and looked at the tadpoles. He didn't think they were that cute. They were just frogs, he saw them all the time and never thought of them as cute.

"Thank you," Buff Frog said from behind them. Star and Marco turned around to see him bowing his head down to them.

"I know you will make great temporary mother and father to them," he said.

At hearing this, Marco's face turned to a deep shade of red and started sweating. "M-mother and father?" he stammered.

He turned to his side to see how Star was reacting. She had a finger on her chin and looked like she was in deep thought.

"Mother and father?" she thought aloud. "Wait a minute, if Marco's the father and I'm the mother, does that make him my-"

"HEY BIG FROG DUDE, BUDDY!" Marco interrupted her before she could finish her statement. "What makes you think we're any good at this anyway?! Don't you someone else you can ask that would be more...I don't know, suited for the job?"

Buff Frog shook his head. "Unfortunately, no. The frog daycares have bad living conditions in the swamps. Trust me, I wouldn't have gone to you two if I had another option. But since I don't, and you two are already married, you would take care of my children well enough for now."

"Hmm," Marco started. "I guess that makes-"

Star froze and heat traveled to her face at the same time Marco also started blushing. What did Buff Frog just say?

"MARRIED?!" they yelled in unison.

The confused giant frog looked at them in confusion. "Yes, what-"

"W-w-wait!" Marco shook his arms wildly. He took a glance at Star to see her looking like she was about to faint. "What-what makes you think we're m-married?!"

Buff Frog looked at the boy questionably. "You aren't married?" he asked.

Marco frantically shook his head yelling no's while Star wobbled where she stood trying to process what it would be like to be married to Marco.

"No no no no no! WE'RE ONLY 14! You can't get married at that age!" yelled Marco.

"But my species are allowed to marry at 14," said Buff Frog like it was a common fact.

"WELL US HUMANS DON'T MARRY UNTIL A LOT LONGER ISN'T THAT RIGHT STAR?!" Marco ranted, waiting for Star to pipe up.

He looked at the girl to see that her head was now somewhat level but was still blushing. "Um, y-yeah," Star squeaked.

Buff Frog was really confused to say the least. "But to get married in my species means that you love the other. Do you not love-"

"NO!" Marco yelled. However, he saw Star flinch out of the corner of his eye and realized what he said. "WAIT! I MEAN YES I DO LOVE STAR BUT I MEAN-"

"Waittt a minute," Star said, not dizzy anymore. She raised an eyebrow toward Marco. "So do you love me or not?"

Marco's heartbeat quickened and found his mouth really dry. "I-I-"

"Wait," Buff Frog interrupted with another comment. "If you are not married, why do I see you cuddle in bed?"

Poor Marco was about to die from embarrassment and awkwardness. Star and him may have cuddled a few (a lot) of times when she needed something to hug but he made sure to keep it a secret. "H-how do you know that?!"

Buff Frog shrugged. "I spy on you when Ludo told me too. Do you not like the cuddles? Is she forcing you into the cuddles?" Marco was left speechless. Thankfully, Star intervened to save him from having to respond.

"I am not!" a blushing Star protested. "He-he loves my hugs as much as I love his!"

Buff Frog raised an eyebrow. "So... you do love each other?"

Now it was Star's turn to stutter as she felt her heart beat quickly, not being able to give a definite answer. Asking Marco if he loved her was a breeze but now that she was confronted with the same question, she realized that she had a hard time answering. "Of-of course!" she let out. "Marco's my best bestie! W-we love each other a-a lot! R-right Marco?!"

The boy's heart started to beat even quicker at Star's statement. He realized that she had basically said that she loved him. "Yeah," he managed all these straightforward questions felt like they were going to overwhelm him.

Buff Frog scratched his chin. "So you love each other... but you don't kiss?"

That was it. He mentioned the dreaded K word Marco had hoped to avoid. The teen boy fainted right then and there and didn't wake up until an hour later where he found himself lying down on Star's bed in her bedroom.

He sat up to see Star playing with the little tadpoles that were still in the water fountain that somehow ended up in Star's room. "Star?" he called.

At the sound of his voice, she quickly turned around and greeted him. "Hey Marco!" she said in her cheerful, confident voice, not blushing anymore. "I'm just looking over these little guys! C'mere!"

Marco got up and walked over and kneeled next to Star who was tickling a tadpole with one of her fingers. He was kind of weirded out at first when seeing the interaction but his heart gradually softened the more he looked at the scene.

"You know, " he started as he put a hand on her shoulder. "They're kind of cute after all. I hope our kids turn out to be kind of like that when we tickle them."

"Yeah," Star giggled as she retracted her hand and let the tadpole swim to play with his brothers and sisters. They both laughed watching the antics of the tadpoles when Star noticed something. She turned to her friend gave him a puzzled look.

"Our kids...?" Star asked him.

Marco's eyes widened as he realized what he said and quickly retracts his arm off her shoulder. His heart began to pick up the pace as he nervously laughs and spouts unintelligible words. "I mean our... our own kids... not our... you know..."

He got up quickly and speed walked towards the door. "I-I have to go and um, do homework. I'll help you out with the frogs l-later," he stuttered, blushing madly as he headed out the room and closed the door.

Star sat there for a while, thinking.

"Our kids," she said aloud, tasting the words as they rolled of her tongue to see if she liked it or not. A smile slowly formed on her face as she repeated the phrase with more confidence.

"Our kids," she said firmly.

She looked back at the tadpoles and sighed dreamily.

"Hear that guys?" she smiled as she repeated the phrase one last time to the tadpoles.

"Our kids."

Author's Notes: Ugh, you see how painful that is? Not adding the stuff of them actually taking care of the frogs? I isn't really have a whole lot of time to extend it since all that in between stuff would've taken me quite a long time but hopefully what I have here is acceptable to you guys for now! I encourage anyone to expand on the idea of babysitting the tadpoles because I think there's a lot of things you can do with it.

Also, credit to svtfoeheadcanons for the brilliant lines of Marco stuttering and explaining what he meant when he said 'our kids' at the end there. That was pure gold that I just had to use the lines he came up with in this fanfiction.

Anyways, hope you guys enjoyed and I'll see you later!
