"Yo, Weiss!" Yang ran over to her after a few minutes. "Are you still mad about being underground?"

"What? No, I've gotten over it." She said sarcastically. "WHAT DO YOU THINK?!"

"…Take that as a yes."

"How can you be so casual about it?! We were in the sewers and I smell disgusting!"

"It's called 'life', you overly dramatic princess. You can take a shower when we get back home." Yang deadpanned.

"At this rate, I'd rather take a shower at Toad Town… I'm pretty sure they have human sized bathrooms, ri-" It then clicked what Yang called her. "Hey, I am NOT overly dramatic."

"Says the girl that was underground and thought she was in a sewer when it wasn't a sewer at all."

"We were underground! That means sewer water!"

"Did you even see any sewer water? Because we sure didn't."

"Underground means the sewer, which means all kinds of nasty stuff. Say what you want, but it's all going to be the same." She said.

Yang sweatdropped. "You're… not going to let that go, are you?"

"Nope."

"…I was afraid of that." She said as Ruby and Blake soon joined them as they proceeded to walk until they saw the next area in front of them, humongous mushroom platforms on top of a grassy field!

World 1-3: Humongously Tall Mushrooms

BGM: Athletic (Super Mario 3D Land)

"So… how are we going to get up there?" Weiss asked as Ruby noticed a sign and read it.

"Jump on these tall mushroom platforms to test your platforming skills! Or, if you don't want to, you can easily walk through the grass and be boring. Either way, you'll reach the flagpole. Contests held every weekend." She read and looked at the bottom. "Number 1 champion: Mario. Second Place: Donkey Kong, Third Place: Toadette. Last Place: Luigi."

"Ouch. Poor Luigi." Yang said.

"He must've had a bad day." Blake said.

"…I'm not going to jump in these high heels." Weiss said.

"Alright, take the boring way, miss boring pants." Yang said as the three of them jumped on the springs and hopped up.

Weiss's eye twitched. "I am not boring! And for the record, I'm wearing a combat skirt!" She said, jumping on the spring and then having the idea to encase part of the mushrooms with ice and then ice skated ahead.

As the four of them were doing their best platforming skills, a few Paratroopas, Paragoombas and Parabuzzies tried to get in their way, but they quickly got over them while Blake stepped on a few of them for extra lift and doing a few frontflips.

A Paratroopa, now a regular Koopa saw Weiss trying to catch up, so he proceeded to stick his foot out… and Weiss tripped over it, causing her to yelp in surprise and fell to the grassy field below while screaming. "OOOF!" She yelped and then got up, glaring back at the Koopa who was sticking his tongue out at him. "Oh, you'll pay for that!"

She then sighed. "I guess I'm taking the boring way…" She muttered and walked through the grassy field, watching her team doing amazing flips. "…I wish I did something like that."

Up above, the trio were racing who could get their first as Ruby activated her Speed Semblance to get to the finish line, AKA the flag pole and then she lept forward, but then suddenly, she felt a foot on top of her as she looked up to see Yang had caught up as she looked down and playfully stuck her tongue out… but then Blake's foot landed on Yang's head and then she lept forward, leaving the two to kiss the ground while Blake landed on the flagpole, doing an amazing handstand on top of it.

"…Show off…" Yang muttered as Blake hopped off as she then noticed a random Beowolf holding a "10" sign, before tossing to the side and getting ready to kill her, but Blake quickly got rid of it instead.

"Hey, where's Weiss?" Ruby asked as they heard a Warp Pipe being used and Weiss jumped out of it.

"Took the boring way, huh?" Yang asked.

"A stupid turtle was responsible for that." Weiss muttered as they went on forward, until they saw a huge castle in front of them.

"Oh, we're at Bowser's Castle already?" Blake asked.

"Let's go!" Ruby said as the four of them ran in.

World 1-4: You are not the Bowser we are looking for…

BGM: Bowser's Castle (Fortune Street)

"Alright, let's go." Ruby said as they walked forward… only to be almost crushed by a Thwomp. "WHOA!"

"Hey buddy, you almost crushed us!" Yang said, but the Thwomp didn't even say anything but lifted up as they proceeded to go on through, seeing various amounts of lava pits and Fire bars.

"…Oh, this is going to be brutal." Weiss said.

"Not unless we're careful." Blake said as they guided their way through the area until they saw some Hammer Bros throwing hammers at them, so Yang jumped over to them.

"Hey, how's it going?" Yang asked and then punched the two of them down.

"Uuugh… did you see that…?" The first asked.

"Fists that can shoot… now I've seen everything…" The other groaned as they proceeded to go through while Blake kicked down a Dry Bones in the lava pit, as they heard it screaming.

"…That's not creepy at all." Yang said as they kept going, making sure not to get burned by the firebars or the fact that some Podoboos wanted to greet them by jumping over some lava pits.

It was then that they were greeted by a couple more Hammer Bros, but then Blake caught the hammers, much to their surprise. "Hey, you can't do that! That's cheating!" A Hammer Bro protested.

"Then how's about you come down and fight us like the men you are?" Yang challenged.

"…Challenge accepted." Another said as they hopped down as they ran over and tried to swing their hammers, but they dodged as Blake threw the hammers back, knocking them out.

"Uuugh, what about fair fighting…?"

"You're the one who threw hammers at us." Yang said as they walked forward and then as soon as they got into the next room, Bowser came down and roared… although it didn't sound like his roaring at all… in fact, he somehow had wheels for his feet, but they didn't really seem to notice.

BGM: Bowser's Theme (Super Mario 64)

"So, you've come to face me?" Bowser asked.

"Yes, more than anything." Blake said.

"We'll defeat you and save the princess and the Mario Bros!" Yang declared.

Bowser laughed. "Then… show me what you're made of, you four."

The four of them got into battle positions and they ran over to Bowser as he only seemed to punch them quite… sluggishly as they quickly avoided it and then quickly slashed/shot/punched him repeatedly.

"Mmmph! Quit shoving…!"

"Oh Be quiet!"

"You're all being hogs, you know that?!"

"Huh?" Ruby looked at her team. "You all heard that, right?"

"We did." Blake nodded.

"Is this actually Bowser?" Weiss asked.

"Of course we are! …Er… I am!"

"…Something's not right." Yang said before punching her fists together and then jumping up in the air, letting out a war cry before punching Bowser, as it basically fell into pieces before it hit the wall… and then they noticed four Koopas on the ground, groaning.

*Record scratch*

"Just… four… turtles…?" Blake asked.

"Wait, so this Bowser was a costume?!" Ruby asked in shock.

BGM: Koopa Bros. Keep Cool (Paper Mario)

"Ugh… what just hit us, a Wiggler bus…?" The red one groaned.

"I think it was more of a Mushroom Food Truck…" The yellow muttered.

"My head's spinning…" The black one complained.

"YOUR head is spinning? I have a headache because of what just happened!" The green one complained as well.

"…Uh, who are you?" Ruby asked.

The red one looked at them. "You don't know who we are?"

"Uh, no."

The red one smirked. "Then allow us to introduce ourselves! We are the Koopa Bros! We're the coolest of cool!"

"…Uh-huh…" Yang didn't sound convinced.

"Red!"

"Yellow!"

"Black!

"Green!"

"And now, we are going to take down… whoever you are." Red said.

"Team RWBY." Ruby said.

"Very well, we will take do-… hold the phone!" Red glared at them. "These girls are stealing our colors!"

"WHAT?!" Yellow yelled.

"That's not cool!" Black said.

"I'll say! We're the coolest of cool and someone goes and COPIES us?! WHO DOES THAT?!"

"Apparently, them!" Black said.

"I told you we should've had our colors copyrighted, but noooooooooo, you didn't listen!" Green said.

"You do realize that none of us are green, right?" Weiss asked.

"Can it, princess!" Green exclaimed.

"Oh you no good-"

"Hmph, the yellow on THAT girl is so tacky, it makes her look ugly!" Yellow taunted. "And girl, what is with the hair? I've seen Princess Peach put less hair extensions on her!"

Yang's eye twitched. "Excuse me?!" She exclaimed.

"You heard me!"

Yang growled, her eyes going green since her Fire Flower power up was still active. "Leave the yellow one to me!"

"I'll take the black one." Blake said.

"I'll take on the red." Ruby said.

"…I guess I'll take on the green one." Weiss said.

"Alright, let's get this show on the road! Koopa Bros… ATTACK!" Red ordered.

BGM: Attack on the Koopa Bros (Paper Mario)

Team WBY and the other Koopa Bros jumped back to deal with their color counterpart while Ruby dealt with Red as they both ran forward and punched each other, but the Red one seemed to grab her by the arm and throw her behind her and then kicking her to a wall.

Ruby immediately recovered and then used her Speed Semblence to tackle him and then launched off of him as she brought out Crescent Rose in its Sniper Rifle form and shot him multiple times but he quickly dodged them and then jumped up and kicked her in the head before backflipping.

"Face it, you can't beat the original!"

"Who's original about you?" Ruby asked. "You're dressed up as a lame superhero anyway."

Red's eye twitched. "How DARE you call me lame!" He said and then ran over and proceeded to punch and kick her as she quickly blocked the attacks before delivering a swift kick to him to knock him away as she switched Crescent Rose's sniper form to the scythe form and ran over and slashed him repeatedly but he dodged each attack gracefully and landed on the blade, causing her to gasp. "Yo." He waved before using an uppercut to knock her into the air and she landed a few feet in front of him.

Ruby got up, shaking it off. "Alright… you asked for it!" She said as she ran forward and they both beat each other up several times before Red managed to knock her away again.

"Face it! You can't beat me at all!"

Ruby clenched her fists and then reached inside her pocket, pulling out a Fire Flower that she had found while jumping over the Mushroom platforms. "I was going to save this for later… but it seems now is a good time." She said.

"Like a Fire Flower will help you!"

Ruby grinned. "It's worth a shot." She said and then closed her eyes, absorbing the Fire Flower as her cloak turned white and her dress turned red, as her hair changed colors to red with orange ends. Crescent Rose also turned white as its main color as well and the blade gains a distinctive flame pattern in the steel.

"Tch, not that impressive."

Ruby quickly aimed her scythe at him and shot massive fireballs from Crescent Rose as he quickly avoided them. "That the best you got?" He asked as he ran forward as Ruby did the same thing, and activating her Speed Semblance, this time leaving fire in her wake and the rose petals turning into fireballs.

Oh, and she was basically a fire tornado as well.

Red's eyes widened and paled as he quickly turned around but then got hit as he was blasted toward the middle as he smacked into Yellow, Black and Green. "Ow! Watch it!"

"You watch it!" Black said as they saw RWBY approaching them.

"You thinking what I'm thinking?" Red asked.

"Our ultimate attack?" Yellow asked.

"Bingo!"

The four got on top of one another and started to charge up. "Behold! Our ultimate attack!" Red said as they proceeded to launch themselves, but Yang got in front and then held back her fist, and then let out a powerful punch that sent them flying towards a wall, knocking them all unconscious.

"Ooogh…" Red groaned.

End BGM

"Well, that was a fight." Ruby said as they all nodded as they walked away and saw a bag in front of them, so they untied it.

"Don't worry, princess, we're here to… save…" Weiss's eye twitched. "A MUSHROOM PERSON?!"

"Hey, I have a name you know! I'm Toad! Thank you, by the way!"

"…But, where's the princess and the Mario Bros?" Blake asked.

"They're at another castle." Toad said.

"…Oh great." Weiss muttered.

"Let's go. The Princess and the Mario Bros aren't going to save themselves." Yang said as they walked away.

With the Koopa Bros…

"Uuugh, they're not going to get away with this…" Yellow groaned.

"Here's what we should do… after we're all feeling better… we follow 'em… and take them down when they're guards are down." Red suggested.

"Good idea… but uh… can we rest for a few minutes?" Green asked.

"Yeah… that oughta be good…" Red groaned.

"My achin'…" Black complained.

Meanwhile, at Bowser's Castle…

BGM: Bowser's Castle (Paper Mario: The Thousand Year Door)

"LORD BOWSER!" A Hammer Bro came charging in. "I have urgent news!"

"Can it wait? I'm in the middle of something." Bowser said, throwing a dart at a dart board with Mario's face on it. "Ah yeah, bullseye!"

"Aww…" A Shy Guy pouted.

"But it's bad news!"

Bowser turned to him. "Bad as in good news for us or bad as in… bad news for us?"

"The latter."

"…Let me guess, Toadsworth is forming a rebellion? That guy can't go two seconds without having a heart attack when Peach is missing."

"…No."

"Some blue guy is having better aim?"

"Nope."

"What is it?"

"The Koopa Bros at the first castle have been defeated by a group of teenage girls."

"…Say that again. WHO defeated the Koopa Bros?!"

"A group of teenage girls."

"…Teenage… girls… as in Teenage Female Toads?"

"No, as in human teenagers."

"…Human teenage girls… just completely destroyed the Koopa Bros?!"

"Yes."

Bowser rubbed his chin in thought. "Who do we have stationed at the second castle?"

"Two giant Pokeys."

"Then they'll never make it over there." Bowser smirked and chuckled. "These teenage girls won't last long… and by the way, what are their names?"

"We don't know for sure, but their team name is RWBY."

"RWBY? As in the diamond?"

"I guess."

"Hmm… well, Team RWBY won't last long in the desert."

"Here's hoping."

Meanwhile… at Beacon…

"Okay, Zwei, time for your walk." Jaune said, putting his leash on him… and then when he opened the door, Zwei took off and started dragging Jaune around. "WHOA! WHOOOOOOOOOOOOOA!"

BGM: Slider (Super Mario Galaxy 2)

Zwei then let him outside in the courtyard. "HEEEEL! HEEEEEEEEEEEEEEEEEEEL!" Jaune yelled, going past Sun and Neptune.

"…Was that…?" Neptune wondered.

"Yep…"

It was then that he past Ozpin and Glynda watched the whole thing, and Ozpin casually sipped from his cup of coffee. "Ten bucks says he'll fall flat on his face." Ozpin said.

"Deal."

"EXCUSE ME, COMING THROUGH!" Jaune yelled, as Zwei was going all over the place as Jaune was trying to control him, but it was no good as he went past Team CFVY as they looked at the two of them with raised eyebrows as Velvet snuck a picture of Jaune being dragged all over the place.

"HEEL! HEEEEEEEEEEEEEEEL!" He screamed as Zwei tackled Cardin to the ground… and then Jaune unintentionally ran him over. "Sorry!"

"…The hell was that for, Arc?!" Cardin growled.

Everyone continued to watch the insanity as Zwei quickly ran back into the building and went back into team JNPR's room where Zwei screeched to a halt and Jaune was launched… and smacked straight into a wall.

End BGM

Ren casually looked up from his book. "So, how was your walk?"

"…That dog is out to get me…" Jaune groaned as Zwei was happily sitting on the ground, panting and looking quite adorable in the process as he happily closed the door behind him, letting out a happy bark in the process.

One world down, seven more to go!
