Hello everyone, welcome to my very first crossover fanfiction that features The Loud House which is a Popular Show on Nickelodeon and Super Mario from Nintendo, I really hope you enjoy it as I worked so hard on it, so if you have any question or concerns about my story you can look me up on discord, my username is on my profile page. I do not own The Loud House or Super Mario, they belong to their respective owners, If you like this story please feel free to leave a review, thank you very much for taking the time to read my new crossover fanfiction story and happy reading.

The story begins with a shot above the clouds; the camera phases through them to reveal the town of Royal Woods, Michigan, 22 Years Ago, to which the camera pans over. A younger Lynn Sr. is dancing out of a movie theater as a song starts to play. As he goes, he finger-guns at a younger Kotaro, who is painting; he thumbs Lynn Sr. up. Lynn Sr. continues to dance in front of Flip's Fruit and Freeze cart; Flip gives him a snow cone.

Woke up just like any morning

New day, same sunlight pouring down

After eating said snow cone, Lynn Sr. dances past a younger Mr. Grouse, who is reading a newspaper. Mr. Grouse takes his eyes off the paper, and his eyes widen.

Danced on to the beat I'm drumming

High hopes pulled my feet off the ground

Lynn Sr. continues to dance. Meanwhile, a younger Rita, as a crossing guard, is busy allowing children and one teacher to cross. She looks over and covers her face with the "stop" sign, but takes a quick peek at the dancing Lynn Sr., who is now dancing in front of the school's entrance. It is love at first sight for Rita.

Heart stopped, didn't see you coming

Felt like you took my breath away

As Lynn Sr. shimmies over to her, Rita turns around and pulls out her compact and lipstick, putting the latter on and swishing her ponytail.

I knew this was the start of something

And I think I knew you felt the same

Lynn Sr. pulls Rita into a twirl. The moment he sees Rita, he too is struck with love at first sight. The two lock each other in the eyes.

Time frozen, eyes open

Spun my world around in motion

Just a step away

Just a slip of fate

The school bell rings, and a lot of children pass, taking Rita with them. Rita collects herself and takes one last look at Lynn Sr., who is touched; he realizes she slipped a love letter into his pocket. The scene changes to their first date at Banger's & Mosh, laughing. The camera spins to Lynn Sr. doing a marriage proposal to Rita in a meadow, and spins again to them getting married before fading to them in front of the recently-sold Loud House.

Oh, you'd never know how one simple interaction

Could lead you down a road

Where anything can always happen

The picture in our mind changes all the time

Bigger than what we'd imagined

We wouldn't change a thing about it now

Life is better loud

Cut to inside the Loud House. Lynn Sr. notices Rita is pregnant and is surprised the baby kicked inside the belly. Lynn Sr. is stunned for a moment, then tenderly hugs Rita's tummy. Camera flashes show baby Lori being embraced by the parents, baby Leni's sunglasses falling over her eyes after she toddles to Rita and hugs her, baby Luna playing with Lynn Sr.'s cowbell, baby Luan playing with sock puppets, baby Lynn interrupting a ball game between Lori and Luna by kicking the ball out the window, and the parents introducing baby Lincoln to his sisters. The sisters all "Aww." at Lincoln and look at each other excitedly. The next few shots show Leni and Lori giving Lincoln a makeover, Luna showing him a rock pose before he taps her nose, Luan performing to the other sisters while using him as a ventriloquist's dummy, Lynn beating him at a game of four-in-a-row, and him about to cry and getting cheered up when his sisters embrace him.

Ain't no stopping now

Life is better loud

The photo zooms out to reveal a photo album. The next few photos show baby Lucy playing with a skull-themed rattle with her bangs grown out, the parents bringing baby Lola and Lana home from the hospital, baby Lisa helping Lori with her homework, and Lily posing happily. The final photo shows Lynn Sr. and Rita in front of the Loud House, followed by their eleven kids with Lily toddling by. The camera zooms in on Lily, and then cuts to her toddling past the logo of the original show. She looks back at the logo, takes off her diaper, hits the logo, and transforms it into a castle now reading Super Loud Bros.

Oh, it feels like home no matter where we are together

Wish we'd always known the bigger crowd was always better

We wouldn't change a thing about it now

Life is better loud (In the Loud House! In the Loud House!)

Life is better loud (In the Loud House! In the Loud House!)

Super Loud Bros!

A second later, a banner reading "Crossover" lands on the logo.
Lily: [to the viewers] "Crossover!"
