DISCLAIMER: I do not own anything in this fanfiction. Jeffy, the SML interpretations of Mario and Rosalina, and the SuperMarioLogan channel belong to Logan Thirtyacre. All rights belong to their respective owners.

NOTE: Before we begin, let me clarify that this is supposed to be a SuperMarioLogan crossover with many works, specifically with the A Kind of Magic cartoon. Despite being a crossover and based on SuperMarioLogan's work, I decided to put this in the Stories/Games/Mario category because it kinda fits the best to me. This is also supposed to be an interpretation partly based on Jeffy's Mistake!, Where's Jeffy?, Bowser Junior's Playtime 4 and Bowser Junior Goes To The Sun!.

Alright, now that we've got all that out of the way, let's begin the story.

...

"DA DA DA DA DA DUN DUUUUN!" introduced Jeffy, a handicapped child who was dropped off at Mario's door months ago. "Pooperman's here to save the day!" he continued as he was wearing a shirt with the word "POOPERMAN" marked on it the whole time, right before he started pooping, unaware that he was pooping in his pants.

"Uh, Daddy? I pooped." Jeffy said to Mario, who was sitting next to him.

"Yep, Jeffy," Mario reluctantly replied, "You saved the day, you pooped in your pants, instead of the toilet like a big boy. Yep, you saved the day, yep."

After a few moments, Jeffy put his hand on his butt, and then moved it around for a while. Squick.

Mario asked him what he was doing. Jeffy replied, "Nhm-taking my butt, Daddy," as he grunted. Mario then heard a knock at the door.

Mario gasped as he realized who was at the door.

"Oh thank God, that must be Rosalina!" Mario said, as he then turned to Jeffy, "Alright Jeffy, stay right here while I get the door OK?" He ran quickly to get the door.

Moments later, Mario opened the door, and it was Rosalina herself.

"Hey Mario!" Rosalina said, as Mario then replied, "Oh thank God baby you're here, I'm living in a nightmare!"

"What's wrong?" Rosalina asked, right when she heard Jeffy's grunts coming from inside. "Oh Lord, what's that?" she said.

"Uh, Jeffy's sticking his hand in his butt," Mario said. "Again?" Rosalina asked.

"Yes, you got him the Pooperman shirt!" Mario replied.

"I did!" Rosalina exclaimed, "I thought it would encourage him to poop?"

"Yeah, it does encourage him to poop-IN HIS PANTS!"

"Well, actually, about that..." Rosalina said.

"Yes?" Mario asked, as he led Rosalina inside.

...

Mario and Rosalina were still having the conversation as they sat on the couch, next to Jeffy, who was still moving his hand inside his butt.

"Uh...I'm headed for a wedding with Jeffy," Rosalina continued.

"Wh- MARRY JEFFY?!" Mario shouted at her.

"Yeah, I'm going to prepare today for a ce-" she was interrupted by Mario. "SINCE WHEN? SINCE WHEN?" Mario asked.

"Just...he is really nice, and I'm more patient around him, and I'm considering marrying him."

"But-" Mario asked, "Jeffy's not old enough to get married, and he's not responsible enough-Look, we got him a cellphone, now he's getting MARRIED?"

"Yes! It'll spare the moment!" Rosalina happily replied.

"Spare the mo-For how long?" Mario said.

"About three days?" Rosalina asked.

"THREE DAYS?!" Mario exclaimed in surprise. "So I have to witness the marriage of you and him in three days?" Mario said, as he then pointed to Jeffy— "THAT THING?!"

"You're gonna be OK, Mario." Rosalina said, as Mario then replied "No, I'm not going to be OK, I really like having you as a girlfriend and I don't want Jeffy separating us, wake up, Rosalina! I don't want YOU marrying HIM!"

"MARIO!" Rosalina exclaimed angrily. "He's beautiful, and he's gentler than you are, he's a good boy, you're just," as she sighed.

Mario sighed too along with her. "Fine," he reluctantly replied, "I'll come to your wedding. I'll watch Jeffy for you."

"Okay," Rosalina replied, "I'll get prepared for the wedding. I will go tell my parents that I am getting married, and I will go do some shopping too, Mario."

...

"I guess I'll see you in three days, then," Mario said as he said goodbye to Rosalina at the door before she left for her three-day preparation.

"It's only three short days, Mario," Rosalina replied.

"Three short days?" Mario said. "It's going to be three long days full of Jeffy and pooping in his pants!"

"Mario," Rosalina replied in a serious tone, "Be nice to Jeffy. He's going to be a good boy for you."

"Okay, make sure to say hi to your parents for me when you visit them," Mario wished Rosalina good luck.

"OK, bye!" Rosalina said before leaving.

"Bye," Mario replied as he left too.
