GL (GalaxyLight): Here's a crossover I decided to do. Mario & Luigi series and RWBY. I was a fan of the Mario & Luigi series, in fact I actually played and finished them all. I'd like to see RWBY come in to their adventures and see how things turn out. I'll also be adding side stories and some will be RWBY related in case nobody wants to miss out. This is a full Mario & Luigi story so it goes from the beginning to the end. Have fun reading!

Fireworks were exploding above Peach's castle because a great event has happened today. The Goodwill Ambassador from the BeanBean Kingdom has arrived. The toads who were wearing sacred robes, were playing their royal trumpets to welcome the Goodwill Ambassador who was wearing a full yellow cloak with a white stripe with red triangles on the head. She was grinning creepily but it is said that what she usually looks like. There was a small person following her who wore similar clothes to her, except it's blue. He was carrying a brown treasure chest as a gift for the princess. The two were approaching her and started to greet her.

"I wish to improve my kingdom's ties with the Mushroom Kingdom." Ambassador stated as she bowed down. "I bring a gift from Queen Bean." The little one walked towards Princess Peach and showed her the chest. The princess walked closer towards it. And just when she was about to open it, the chest suddenly opened by itself revealing a mysterious toy with a spring. It opened its mouth and suddenly sprayed out green smoke into the princess's face. All the toads' eyes widened in shock to what just happened. They were even more shocked to when they heard Ambassador's terrifying laugh.

"Eeeyah ha ha ha ha!" She laughed loudly. She then suddenly reveal her true form. She wore a purple robe with a pink dress inside and a puffy collar. She had two strange purple opal-shaped accessories on her head. Her face looked like she was an old woman, frankly enough, she is an old woman. She summoned lightning around the area, causing the toads to flee from the castle as the whole room became colourless.

The little figure revealed himself with a red cloak round glasses with a big grin. Something then fell down onto his head. It was a green dome with two jet packs between it while the top had some kind of mouth-shaped vacuum. It sucked away the green smoke that was covering peach. As it got away from her, she immediately collapsed from shock and lost air. The two figures laughed evily as they both left the castle with glory.

At Beacon Academy, Team RWBY, formed with Weiss Schnee, Blake Belladonna, Yang Xiao Long and the team leader, Ruby Rose, were asked to meet with Mr. Ozpin at his office. The four of them lined up side by side and positioned themselves like soldiers, waiting for the headmaster to speak.

"Team RWBY, I'm sending you four on very impoartant assignment." Ozpin started talking.

"What is it? Is it something grand, adventurous...? Oh! Perhaps maybe something that isn't from here!" Ruby cried out with sparkly eyes as she was excited about what quest the team will be assigned to. Weiss just groaned.

"Be serious about this, you dunce!" She scored her. Ruby just pouted.

"Actually, Ruby, you may possibly be right about that last statement you just made." Ozpin smiled surprising the four huntresses.

"What do you mean, Headmaster Ozpin?" Blake asked him.

"Well, to put it simply," Ozpin then showed them a screen beside them and it turned on automatically. What appeared in the screen was a green warp-pipe surrounded by green grass. It was completely at a place out of nowhere. "we have witness a mysterious object what appears to be a green pipe." He explained. "It isn't just a normal pipe, not one that leads to underground. It is a pipe that leads to another world or so they say." This gave a shock to Team RWBY but also confusion.

"Or so they say?" Yang asked.

"James Ironwood, the leader of the Atlesian military, sent in some soldiers to investigate where that pipe leads to. Our results was a path to another world, something about mushrooms and turtles living in that area."

"Mushrooms and turtles? That's kind of... disorienting." Weiss commented.

"Everything here in Remnant is." Yang informed her.

"It is so not!" Ozpin fake-coughed to get their attention which they did and stayed quiet until he could speak again.

"What the soldiers saw did not appear to be a threat, but Ironwood is worried it could be dangerous if not careful by its cover."

"So you want us to go in there and look around?" Yang asked specifically. The headmaster nodded.

"I'm not ordering you four to investigate. It is your choice whether you want to accept or not. Remember, this is an high-class mission, so it would be wise to think about your answer."

"High-Class mission you say..." Weiss held her chin with her hand, thinking that this mission might be worth doing. 'If I can complete this mission, then my rank will go higher.' She thought with a smile.

"Sounds like an adventure! I'm so in!" Yang smiled as she cracked her knuckles.

"Me too! I can't wait to see what new stuff there will be there!" Ruby agreed as she was jumping with joy.

"This could be dangerous, but if everyone here is tempted to go, then I guess I will have no choice." Blake sighed as nodded.

"What about you, Weiss? You coming too? Though we could leave you here and see the greatest things in that pipe." Yang teased causing the white-haired girl to twitch in anger.

"And leave me alone while you three are away!? Not a chance! We supposed to stick together as a team, and that's why I coming too if you're all accepting this mission!" She blabbered out causing the two sisters to laugh. Ozpin just chuckled.

"My, aren't you an energetic group." He smiled. "It's decided then, you are allowed to investigate the new world from that pipe. I will wish you luck when you leave. However, there's one thing that needs to be done first. I want you four to lend me your scrolls." Team RWBY became very confused.

"Huh? What for?" Ruby asked.

"I want to make a few updates and modifications with them before you go, if you don't mind if you meet me at the entrance of Beacon Academy. I'll see you there once I have finished." Team RWBY looked at each other and nodded as they placed their scrolls on Ozpin's desk before exiting the office.

After the four girls were at the entrance, they waited for a couple of minutes when Ozpin finally came to see them. "Sorry for the wait. Here you are." He showed them their scrolls which was stacked like a rectangular prism. The four grabbed their scrolls with mistakes and checked their scrolls to see what they got, but they couldn't find anything.

"So... what's the update?" Ruby asked Ozpin.

"I have upgraded your communication signals and contacts allowing you to not only contact others from very far distances, but also at Beacon Academy." Ozpin stated causing the girls' eyes to widen in shock. "Since you'll all be heading on a dangerous journey. I want to contact you all to see how you fare and ensure you are still alive. We can't have Huntresses lost in a new place they haven't been to, can we?" The girls smiled except for Weiss who didn't like the last sentence. "I'm afraid this is all I can give you . The rest is all up to you. I'm counting on all of you to be safe and look for anything discreet."

"Don't worry, Oz. We'll be back with lots of souvenirs and food!" Ruby smiled as the four left to find the warp pipe. Ozpin just smiled.

"I'll look forward to that."

"Are we there yet!?" Ruby groaned out loud as they have been walking for few hours.

"Ruby, if you dare ask that one more time, I'm gonna-!" Weiss could not finish her words when Yang spoke up.

"There it is!" Yang yelled out as she was pointing at the same green warp-pipe they saw on the screen.

"Yay!" Ruby cheered as she was running towards it. Weiss just face-palmed but she was glad that she finally doesn't have to hear Ruby say 'Are we there yet?' anymore. The girls looked down the pipe to see where it leads to, but it was all pitch black. "I can't see anything there." Ruby exclaimed.

"Probably because we're heading to another world, it would be a long way." Blake told her.

"Whatever works. Let's be careful though, who knows what will happen if we go i-"

"Hup!" Weiss couldn't finish her sentence when Yang climbed up to the warp-pipe.

"LAST ONE'S A ROTTEN EGG!" Yang shouted as she jumped into the pipe, much to Weiss's dismay. The rest of the girls couldn't see her anymore once she jumped in.

"Hey! Wait for me!" Ruby cried out as she was the next one to jump in the pipe. The black and white huntresses have nothing to say until, Blake spoke first before climbing up to the pipe.

"I guess you'll be the rotten egg on this one." She joked before jumping into the pipe.

"Rotte- I'll show you rotten!" Weiss shouted angrily, although she was the last one to jump into the pipe and head to the world of the Mushroom Kingdom.

Luigi was peacefully hanging his brother's clothes while whistling as one of the toads came to their house panicking. "E-E-E-E-EMERGENCY SITUATION!" He shouted freakily. Luigi turned to see the toad in confusion. "DID YOU SEE THE KINGDOM COURIER!?" Luigi just shook his head. After that, the toad ran pass through him and entered the brothers' house to find the red plumber. "MARIOOOOO!" he called out but nothing happened. He decided to look around to see where he is. He looked everywhere except for the bathroom room. The door was open as steam were flowing out of the door. He could also hear humming from the room.

'Hmm? I hear humming...' The toad thought to himself as he entered the bathroom. What he saw right now is something that no one in the entire world would ever want to see. "EEEEEEEK!" The toad shrieked as he came out with a completely red face. He was freaking out and accidentally rammed himself into a wall.

Mario saw what happened and came out of the bathroom with just a towel covering his lower half. He saw the toad lying there with a red face. He jumped on him a couple of times to get a response. "P-P-Princess P-P-Peach... P-P-Princess P-P-Peach..." He slowly said repeatedly. This causes Mario to panic a bit realising that the princess of the Mushroom Kingdom is in trouble. He dashed outside to collect his clothes, despite that they're still drying right now. Mario didn't hesitate since he was on an urgent mission, he leaped to the overalls and quickly changed into them in almost 10 seconds. After that, he headed to Peach's Castle, but little did he know that his overalls got caught on a rope with Luigi tied up to it as he was being helplessly dragged by his brother.

Somewhere around another area, a normal green warp-pipe was surrounded in a quiet hill. But the silence disappeared when a blonde came out of it as she stuck the landing on the ground. She smiled from her triumphant which lasted poorly after Ruby crashed into her, followed by Blake and then Weiss.

"OOF! HEY! OW!" Yang groaned in pain as each one of them increased the weight below her. "Get offa me!" She lifted herself up causing the rest of the girls to tumble down to the ground.

"Geez, be careful when you do that. You almost got my clothes dirty." Weiss complained as she was getting up. Yang just yawned from her complaint and looked around to see where they are.

"Whoa! Are we on a mountain?" Yang questioned.

"Looks like it." Blake answered as she looked around. It was quite a sight for them. There were lots of other hills, there big trees and tall mushrooms, there were birds chirping, it looked so normal, almost like Remnant... without the Grimm of course. "What a sight." Blake commented.

"I know! I can't wait to see what's new here, especially when we're going to that castle." Ruby exclaimed.

"Castle?" The other girls asked in confusion. Ruby pointed to the castle she was talking about, and she was right. There was a castle and also a small town in front of it from where they can see.

"Let's go and see what the people there have to say about this place." Weiss told the team. "Though I have an odd feeling that it's not a good thing right now."

"You're just exaggerating, Ice Queen." Yang smiled as Weiss twitch in anger when she was called that. "Come on! The one who gets there last, owes us a drink!" She then jumped off the hill and slid down the rocks.

"Don't bet on everything when it's not even a race!" Weiss complained loudly but Yang couldn't hear her, she was already down to the forest.

"Move it or lose it, Weissy." Ruby laughed as she jumped off as well. Weiss groaned loudly as she was called a nickname again.

"Hey! Don't go off without us!" Weiss shouted as she used her magic to jump down to the forest. She didn't want to scratch her shoes if she were to slide down the rocks. Blake just sighed.

"I wonder if we'll ever get anywhere with this relationship." She said to herself before jumping off to join her team.

GL: I decided to stop here. I know it's kinda short, but it's the best way to start a prologue, you know? Don't worry, I'll do a longer one in the next chapter so don't get your hopes down.

How do you like the Outtakes? I would like to see what was behind the scenes of a story, as if they were in a movie and trying to rehearse the story. So enjoy these.
