BGM: Waltz of the Boos (Super Mario Galaxy)

"AAARGH! GET US OUT OF THIS MESS!" Grif yelled as he was obviously scared by the Boo Buddies circling around him, same with Jaune. It was bad enough with the big bubbles, but now these Boos were just messing with them.

"Yoshi…!" Yoshi growled, grabbing Jaune by his tongue and putting him in his mouth, then grabbed Grif and had him sit on his saddle as he ran straight to the door, opening it and then walked outside where everyone else was at. He proceeded to spit Jaune out while knocking Grif off of him.

End BGM

"…I am so using the shower when we get back to Beacon…" Jaune groaned. "And doing laundry…"

"…Guys, weren't the Mario Bros with us?" Sun asked.

"We're also missing RWBY." Ren said.

"And Nyx." Pyrrha piped up. "I wonder if they got side tracked with something."

"Eh, they'll catch up. Let's go. I know we're getting closer and closer to that Bowser fellow." Sarge chuckled as the Reds and Blues agreed, but the others were a bit worried though. They walked off, as they saw a huge platforming area in front of them.

World 7-3: One Second Platforms

BGM: Athletic (New Super Mario Bros Wii)

"Well, this shouldn't be too bad." Jaune said as they ran forward as they jumped up on the Paratroopas with ease, although some of them moved to the side to mess them up and then they proceeded to headbutt them, mostly Jaune. "Oh, knock it off!" He growled, slashing a Paratroopa away as they kept going.

"What's HIS problem?!" The Paratroopa growled.

"Oooh, what are these?" Nora asked, seeing a grassy moving platform as she happily jumped on top of it as it moved for her… only for it to fall as she fell as well, but luckily for her, she landed on a Koopa to cushion the blow, much to his dismay. "Aww… I broke it." She pouted.

"It's not the only one that's broken…" The Koopa complained with a groan.

"Hmm, I think these platforms have a timer on them." Ren said.

"What makes you say that?" Nora asked.

"If I had to guess, these platforms let you stay on for a number of seconds. See that with the number one?" He asked. "I assume you stay on it for one second before it falls."

"Bullshit!" Church said as he hopped on one… and one second later, he fell. "…Okay, you might be on to something."

"Weee!" Caboose said, falling with the platform and crushed a Koopa.

"MY SPINE!" The Koopa screamed as they noticed the ground was going away, so they had to jump on the platforms to keep going, with 1 being the most common and 4 being the rarity. They jumped through platform to platform, although the Paratroopas weren't making it easy, and neither were the one second platforms, but they managed to keep at it.

"Hey guys? I think I see some Banzai Bills up ahead!" Sun said.

"Oh, lovely!" Church groaned as he hopped on a four second platform and aimed at the Banzai Bill before firing… but alas, his shot didn't even graze it. "Agh!"

"Has anyone told you that you're a horrible shot?" Tucker called out.

"I'm a little rusty, dammit!" Church growled.

"Riiiiight…" Tucker didn't even believe him. They proceeded to dodge the Banzai Bills with extreme difficulty, as one was headed right for Jaune as he landed on a platform.

"Oh, come on, that's not fair!" Jaune groaned, but then the Banzai Bill swerved around him and kept going. "…Huh…?"

"Hello!" Pyrrha cheerfully waved over to him.

"Thanks, Pyrrha!" He waved back and they kept going until they reached the end.

"…Where's Nora?" Neptune asked.

"WAHOOOOOOO!" Nora yelled as she was riding on a Banzai Bill as she hopped off before it landed on the ground, causing it to explode. "Yo!"

End BGM

"…I'm not even going to ask." Simmons said as they walked off… which they proceeded to find another cave.

"Can we take the long way around?" Grif asked.

"Nope." Sarge replied by dragging Grif in.

"Yeah, stop being a pussy, Grif." Sister chuckled.

World 7-4: Watch For Falling Rock

BGM: Underground Theme (Super Mario 3D World)

"Whoa, incoming!" Jaune exclaimed as they dodged a small boulder from crushing them as they turned to see a Chargin' Chuck digging up more rocks and sending it at them, also known as Diggin' Chucks. "Hey, what's the big idea?" He asked as Church shot him, but all it did was hit the ceiling.

"I think you're getting rustier by the minute." Tucker said.

"It doesn't make sense! He's in my line of sight in the scope!" He complained as Nora jumped up and hammered him into the lava, while taking a Paratroopa with him.

"Oooh… I'm sure he'll be fine." Nora said, completely unaware that there was lava in the cave as well, forcing them to traverse carefully… while Poochy decided to take a nice hot bath for the fun of it. They went onward where they went down while being careful not to fall in the lava, but if they did, Poochy was right there to save them. Yoshi even swallowed a Koopa and aimed carefully before sniping the Diggin' Chuck with his own egg.

"He's a better sniper than you are." Donut said.

"Oh shut up!" Church growled.

"Heh, I'd love to see him try out a bazooka." Sarge said.

"…Are you trying to say give the happy-go-lucky dinosaur a bazooka? That's just asking for trouble." Grif said.

"Hey, he sniped that guy easily with an egg. I'm sure a bazooka would be up his ally!"

"I wholeheartedly agree, sir!" Simmons said.

"Heheheh, see, he gets it!"

"…Am I the only one opposed to this idea?" Grif asked as they went onward, taking care of more Diggin' Chucks along the way and carefully traversing the lava before they eventually got out of the cave.

End BGM

"Sweet freedom!" Grif exclaimed.

"Yes… but look at what's ahead." Ren said as they saw Larry's castle in front of them.

"…Oh great…" Grif sighed. "So, who's left?"

Jaune read the sign. "Larry."

"Well, he's probably the only one left before we have to take on Bowser." Nora said. "Shouldn't be too difficult!"

"I say we wait for the others, that way, we can take Larry on together!" Jaune said. "What do you say, guys?" He turned around. "Guys?" He asked as he saw blinking white outlines of where everyone was at, and then he heard the door slam. "…Guys! Wait for me!" He said and ran on in.

World 7-Castle – Larry the Cheater

BGM: Bowser's Castle (Fortune Street)

"…Please tell me that's not what I think it is." Church said.

"Yup. Snake Blocks." Donut sighed.

"Oh, that's GREAT." Sun groaned as they got on the snake blocks and sloooooowly made it across the lava.

"Yoshi Yoshi…?" Yoshi wondered.

"Yes, it's very boring." Caboose said.

"…Caboose, did you just understand him?" Church asked.

"Was I not supposed to?"

"…Never mind!"

As the slow journey continued, it finally came to a complete stop as they hopped off and they went onward through the next area where Nora let her frustrations out by knocking several of the Dry Bones into the lava and also destroying block walls, also knocking out some Magikoopas in the process and destroy every spike in the room until everything was basically destroyed.

"I'd do the same too." Donut said.

"You feeling alright?" Pyrrha asked.

"Yeah, I feel better." Nora smiled as they walked forward until they reached the final door and then they walked in.

End BGM

"Haha! Welcome!" A voice called out as Larry landed in front of them. "I'm so glad that you could… make… it…" He blinked. "Where's the rest of you?"

"Lagging behind." Church said. "I say we do it without the-"

"Hold it! I prefer if Mario and the others are here. It's not the same without Mario! Besides, I wanna see the firepower of RWBY anyway."

"Are you kidding me?! I'll never agree to that!" Church growled.

A few minutes later…

"Sooo, do you have any fives, Jaune was it?" Larry asked, as he was playing cards with Jaune, Nora, an annoyed Church, Sun, and Sarge while the rest were just minding their own business.

"…Ugh! Yes, I have three of 'em…" He groaned as he handed them over.

"Sweet!" Larry chuckled, and then felt someone was looking behind his shoulder to see that Nora was peeking.

"Oooh, I'd play that one." Nora said.

"This one?"

"No no no, the other one."

"This one?"

"Yes."

"Oh ho! I see here! Yeah, I'll definitely play that one!"

"I didn't know Nora was Bugs Bunny." Caboose said.

"That's because she isn't." Church said in annoyance as Nora resumed her game before whispering in Jaune's ear, unbeknownst to Larry.

"Sun, do you have a three?" Sarge asked.

"Nah, go fish."

"Dagnabbit!"

"Larry, do you have any… sixes?" Jaune asked.

"Agh! I was hoping you wouldn't have guessed that! I have like four of the-… hey, WAIT A MINUTE!" Larry yelled, glaring at Nora. "I see what's going on here! You're helping him win!"

"No, I'm not." Nora innocently smiled.

"Yes you are, you double agent!"

Suddenly, the door was shot opened to reveal Yang as the others came in… only they were a little confused on what's going on.

"…Did we miss something?" Mario asked.

"Oh good! You're here! Let's get this over with!" Larry grinned as he hopped back up as everyone got into position.

"Let's do this!" Yang smirked.

BGM: Boss (New Super Mario Bros Wii)

Larry jumped up, firing his magic at them but they quickly dodged as the magic hit the walls but it bounced back and it nearly grazed Ruby as she used her semblance to slam into him to knock him away but he recovered and then jumped near them, firing more magic before firing magic on the floor, causing pillars to rise to make it harder, then he jumped into his shell and spun around.

"Heads up!" Nora exclaimed, hammering Larry to stop him before hammering him away to knock him towards a wall to knock him back as Neptune and Nyx shot him a few times before he hopped off of the wall as he proceeded to launch more magic, but to his dismay, they were dodging his attacks easily before they wailed on him repeatedly until they jumped back.

"Argh… alright, that's it! I'm gonna-" Mario and Luigi used an uppercut with their hammers to knock him up in the air before Nora jumped up and hammered him away and out of the castle. "AAAAAH! I'LL GET YOU FOR THIS, CHEATER!" He yelled before a star shined brightly in the sky.

End BGM

"Cheater? Do I even want to know?" Weiss asked.

"Don't worry about it." Nora said.

"…Oh my goodness!" Nyx exclaimed as they turned to her. "Larry had two eggs!"

"Two eggs? Interesting." Mario mused as they walked outside while blowing up the castle, as the first one opened up to be an Orange Yoshi as it cried out in happiness before running off, but the other one refused to open.

"What's wrong, little fella?" Nyx asked as she looked at the one egg, as it simply rolled towards her and seemed to cuddle her.

"I think that one likes you." Ruby said.

Nyx giggled. "I'm pretty sure it does." She said.

"Can we make an omelet out of it?" Grif asked.

"Don't even think about it!"Nyx warned as they wandered off and they saw a huge army of Grimm in front of them.

"…That's a lot of Deathstalkers and King Taijitus…" Sun said.

"Sooo, how are we going to get past them?" Neptune asked.

"Oh!" Sarge pounded his fist into his palm. "Men, I have the most wonderful idea on how to do it!"

"And that would be?" Grif asked.

"Live bait!"

"…I HAD to ask!"

"All I need are a few things." Sarge said. "Someone fetch me a hula skirt, an apple and a big pig."

"OH NO, I AM NOT WEARING A HULA SKIRT!" Grif yelled.

"That sounds hot!" Sister grinned. "I'll be the hula girl… I just need to take this armor off." She said, ready to take her helmet off. "Besides, I've always wanted to do it naked!"

"WAIT, WHAT?! No! Don't do that!" Jaune yelled, as she had already taken off her helmet, though her face was being blocked from the viewer. Or the reader in this case.

"…Why not?" Sister asked.

"Because we don't need to!" Sarge said. "Grif will be the pig and Simmons will be the hula dancer!"

"Aww…" Sister pouted before putting her helmet back on.

"WHAT!" Simmons and Grif yelled as Tucker chuckled darkly as he found a bush and began cutting it with Blake's katana, which he took while she wasn't looking, before it was made into a hula skirt. Blake punched him after getting her weapon back.

"…We need a ukulele." He said.

"Dag nabbit, I left that at home!" Sarge growled.

"You can use mine." Caboose said, holding one.

"Thanks!" Sarge said, giving it to Simmons. "Now, you need lines!" He said, pulling out a piece of paper and writing it down before handing it to him.

"…Oh no, I am not reading this! This is embarrassing!"

"Oh, give me that!" Grif said as he read it. "Luau, if you're looking for a big fat juice meat, eat my buddy Grif here because he has… a treat…?! I'm… a big… pig… achin for… BACON?!"

"Whoo! Bacon!" Donut cheered.

"That sounds hot! …And tasty!" Sister grinned.

"NO NO NO NO! I REFUSE!" Grif yelled, crumpling up the piece of paper and throwing it away, unaware of it hitting a King Taijitu and catching its attention. "FUCK YOU!"

"What was that?!" Sarge growled.

"Fuck you, SIR!"

"That's more like it! Now, I say we go with that plan!"

"…This is so not going to work." Church said.

"Oh, like you have any ideas?" Sarge asked as they began to argue while Grif and Simmons felt something… threatening as they turned to see all the Grimm glaring at the two of them.

"…Ooooh…" Simmons paled. "Hi…"

One of the King Taijutus roared at them, causing both of them to lose their color and they quickly ran away, with all of them following them. "SHIT SHIT SHIT SHIT SHIT SHIT SHIIIIIT!" They both yelled.

"…Dag nabbit! They didn't even get to the good part yet!" Sarge complained.

"Uh… there is a back door that we could've taken." Blake said. "We found it completely by accident."

"A back door, you say?" Sarge asked. "Make ourselves undetected by the enemy! Genius! Take us there!"

"…Are they going to be okay?" Pyrrha asked in concern.

"Eh, they'll be fine." Sarge said as they wandered off, while the non-Reds and Blues looked at Grif and Simmons in concern.

"GRIF, PICK UP THE PACE!"

"I'M RIGHT IN FRONT OF YOU, DUMBASS!"

"AAAAH! DON'T GET ANY CLOSER!" Simmons yelled.

With Bowser…

"So… they defeated all of the Koopalings…" Bowser said. "...Very well then, I'll be taking them down by MYSELF!" He roared before looking outside. "…Eh? Where'd all the Grimm go?" He wondered.

RWBY's Castle Calamity! (Part 7!)

BGM: Going Somewhere (Mario Party 2)

"Alright, that's it!" Ruby growled, pulling out a Fire Flower and then absorbing it as she proceeded to launch fireballs everywhere at the castle, but to no avail as she quickly used her semblance to fly and go around the castle, where the fire tornado consumed the castle, but when the tornado disappeared, the castle didn't even have a burn mark at all. "ARE YOU KIDDING ME?!"

"Ugh, great..." Yang groaned.

"Poyo..." Kirby rubbed his non-existent chin and then thought of something. "Poyo!" Kirby ran over and pulled out his hammer, as he hammered it several times before charging up his Hammer Flip and then unleashed it, but once it hit the castle, his hammer came flying off and smacked into Grif's crotch.

"AAAAAGH!"

"...Poyo..." Kirby awkwardly rubbed his head.

Luigi thought of something. "Wait a minute!" He said as he looked at the palm of his hand. "I've actually been working on this for a while." He said as a spark of electricity formed in his hand.

"Luigi?" Mario asked in amazement.

"Heh, you can thank the Master for teaching me this technique!" He grinned as he ran over and charged it up. "THUNDER!" He yelled, shocking the hell out of the castle... until a lightning bolt shot out of the castle... and then it struck Luigi. "YAAAAAAAAGH!" He cried before falling to the ground. "...Ow..."

"Oh, I could use some of that!" Nora said.

"Poyo!" Kirby said as he attempted to inhale the castle, but it wasn't budging, so he inhaled even harder as it finally moved and then was sucked inside Kirby's stomach. "...Poy..." He groaned, trying to swallow it but he was starting to turn green and getting sick as he turned around and spat it out... right on top of Church. "Poyo..."

"WHY ME?!" Church yelled.

Take 2

Kirby looked at Nora and grinned, before sucking her up. "Whoa... whoa... WHOOOOA!" Nora yelled as she was sucked in to him, before he spat her out and then gained Nora's hair.

"Hiiii!" Kirby waved.

"...I have seen some things that I didn't need to see..." Nora groaned before seeing Kirby pulling out his own hammer that looked identical to Nora.

"Poyo poyo?"

Nora hopped back up, seeming to be back to her perky self. "Sure!" She grinned, pulling out her hammer as they both jumped up and hammered the castle together, squishing it... but they both were launched up in the sky before Kirby landed first... and then Nora squishing him. "OOOF! ...Oh my god, I killed Kirby!" She exclaimed as she got off, but Kirby popped back up just fine.

"Poyo!" He giggled and then saw the castle still standing. "...Poyo..." He sighed.

"Okay, castle! We need to talk!" Doc walked over to it. "Would you kindly crumble to dust so we can move on?" He asked... only for the castle to pull out a sign that asked "Who are you and when did you get here?" causing Doc to jawdrop and faint at the sight.

"...Ouch." Church said.

"Forgotten by a castle... that's gotta hurt." Sun said.

"AAAARGH!" Yang yelled. "IS THERE ANY WAY TO DESTROY THE CASTLE?!"

"...Wait a second!" Ruby said. "Has Caboose ever had a turn?" She asked as they all looked at Caboose.

"Hello!"

"...I don't think so." Yang said.

"...Guys, I have an idea!" Church said, as they formed a group circle and whispering before they looked at Caboose.

"Hmm? What are you looking at me for?" He asked before turning to nothing. "I think they're gonna use me for something for the last one, but I'm not sure what." He said.

All that's left is Bowser himself!

Stay tuned!
