Hello Everyone! I've come up with this short story here as a kind of inspiration from a chapter of my friend jpkurihara's story 'Mario and Yoshi: Sleepy Squad.' It's a short AU of Mario and Yoshi meeting each other as kids, but then forgetting each other as the years go by until they meet each other again when they're grown adults. However, both of them don't know who the other is, not knowing that they somehow got reunited again. Please enjoy reading this story and thank you for taking the time to read this author's note! =D

It was the Princess who actually suggested the idea of a vacation. She wanted to reward Mario and Luigi for their valuable help in saving her from Bowser once again. She decided the vacation would be in a place she use to visit in her youth.

"D-Dinosaur World?" Luigi stammered, fearfully imaging giant, prehistoric dinosaurs roaming the land.

"Yes Luigi." Peach replied. "Don't worry there isn't anything dangerous in Dinosaur World. The natives are all kind, pacifist folk who welcome newcomers to their land."

Luigi sighed in relief. He was still a bit anxious, but in the prospect of going to a new world he never heard of before. Mario on the other hand was nearly jumping with joy.

A vacation? Who wouldn't be excited?

And going to a new place he never heard of before made Mario's adventuring senses tingle. The minute they arrived to Dinosaur World, he would run all over the land, exploring every nook and cranny until he fell down from exhaustion.

If only life were that simple to the poor red-hatted plumber.

When they had arrived, both Mario and Luigi found orange-striped feathers on the ground. Curious on what it was, the two each picked one up before they suddenly felt themselves transform.

The feather was gone from their hands, but in place was a bright yellow cape on each of the brothers' back. Excitement coursed through the both of them as they ran at breakneck speed across the green plains, before suddenly feeling their feet leave the ground.

"M-Mario! We're flying!" Luigi called out excitedly, looking down at the ground below.

Mario had the widest grin on his face as he bellowed out a loud Yahoo, and flew even higher into the air.

He took in the view for a moment, and closed his eyes.

For a few seconds he felt at peace.

"MARIO!"

Mario suddenly opened his eyes, and turned towards Luigi, who had a look of worry on his face.

"What's wrong bro?"

"P-Princess Peach is missing!"

Mario's eyes widened in fear, but attempted to hold his composure.

"Are you sure Luigi?"

"Yes! I flew down a bit near the hot air balloon, and didn't see her anywhere!"

Mario followed Luigi, and landed on the ground near the hot air balloon they all came in to Dinosaur World.

"Oh stars…"

The hot air balloon was torn to shreds, and the luggage that the three had brought with them was thrown all over the place.

Luigi turned to look at Mario.

"What are we gonna do now big bro?" He asked, unsure.

Mario stared at the torn hot air balloon. All he wanted was to have a single peaceful day, but Koopa had to come in and ruin it anyway.

But now wasn't the time for self-pity.

It was time to take action.

'Bowser's going to pay.'

"Luigi." Mario sharply called out to his brother.

Luigi stiffen and glanced at Mario. His big brother was in hero mode now.

"I need you to stay here and make sure none of Bowser's lackeys come back here to play. If you see any of them in sight, I want you to give them a beating they won't forget."

Luigi chuckled, and nodded his head. "Understood bro."

Mario smirked, and tipped his red hat to Luigi, and began to run off into the beginnings of a brand-new adventure ahead of him.

Luigi looked at the fleeing red dot that was his brother, and sighed.

"Good luck Mario."

As you could already tell this takes place in Super Mario World, but a more condensed version of it. Since it's a short story of some sorts, I won't be going through each world and the bosses, and whatnot.
