World 3-1: Fun in the Sun!
BGM: Beach (Super Mario 3D Land)
The four of them hopped out of the Warp Pipe and saw that they were at Cheep Cheep Lagoon, seeing a ton of Toads and friendly Koopas sunbathing on the sand while a few Toads were surfing.
"So we go from a grassy area to a freaking hot desert to… a beach." Weiss said.
"Surfs up, dude!" A Toad ran near them and dove in the water with a surf board and proceeded to swim over as a few Cheep Cheeps jumped out of the water.
"Hey guys, check that out!" Blake said, pointing to a building as there was a sign that said "No swimsuits? No problem! You can get one here!"
"...You thinking what I'm thinking?" Yang asked.
"Oh yeah!" Ruby exclaimed as the three of them took off running.
Weiss sighed. "Alright, but let's not have too much fun..."
A few minutes later...
The four girls walked out of the building, wearing completely different swim suits.
Ruby is wearing a one piece swimsuit that was dark red like her outfit, completely with rose petals scattered across her suit.
Yang has a two piece suit with the top being yellow with her symbol on it, and her bottom being black with fire.
Blake has a black one piece swimsuit with a little red tinge.
Weiss has a white one piece that was covered in snowflakes.
Their clothes are in a blue waterproof bag so their clothes would be dry while underwater, and then the four proceeded to dive right on in, splashing and laughing, and all of that fun stuff.
Fifteen minutes later...
"As much as we're having fun and all... I think we should go and save the princess and the brothers." Weiss said.
"Oh, alright..." Ruby said. "But I'm keeping this cute bathing suit on!"
Weiss smiled. "As am I."
They got out of the water and dried off as they proceeded to walk along a path as there weren't too much trouble going on as they noticed a Beowolf relaxing in the water… in fact, it was floating on top of a inner tube.
"That… is so cute, even if it is a Beowolf. Where's Velvet when you need her?" Yang asked as they all laughed as they walked away, running into the occasional Goomba as they walked across a bridge where some Cheep Cheeps seemed to be enjoying jumping over the bridge for fun.
As they were crossing, Weiss casually turned her head to see a Cheep Cheep jumping and smacked right into her head… but oh no, it didn't stop there. It proceeded to give her a big wet fishy kiss on the lips that the rest of the team just so happened to notice as they were snickering.
The Cheep Cheep proceeded to dive back in the water as Weiss looked like she was about to scream at any second… and she let out one of the most eardrum shattering screams of all time that scared a few birds away.
"DID A FISH JUST FREAKING KISS ME?!" Weiss screamed.
"Hey, at least you had a first kiss." Yang said.
"And it was from a fish!" Ruby grinned as they burst out laughing.
"NOT FUNNY!" Weiss yelled as she chased after them while Blake was staring at the Cheep Cheeps and pulled out a random fork and knife and a Cheep Cheep jumped over and Blake grabbed it.
"Mine!" She exclaimed as the Cheep Cheep paled up… until a huge shadow went over them as she looked up to see none other than Big Bertha coming in and chomping up Blake, much to the relief of the Cheep Cheep as it hopped back into the water.
As the two sisters were running from an angry Weiss, they proceeded to hit the flagpole and then Weiss tackled the both of them down in anger, before realizing Blake seemed to be missing. "Hey, where's Blake?" Yang asked.
A shadow overlapped them again as they saw Big Bertha coming out of the water and spitting out poor Blake as it went back into the water.
"Did you just get eaten by a fish?" Weiss asked.
"I'm never going to eat fish again for as long as I live…" Blake said, crying anime-style tears as Ruby hugged her in comfort as they proceeded to walk and noticed a sign.
"Deep Sea Diving! Use a Frog Suit or a Penguin Suit to go in and get the flagpole on the other side… but be sure to look at all the aquatic life!" The sign read as they looked at two ? blocks as they hit them, and out came four Frog Suits and Penguin Suits as they looked at them… before they all went to the Penguin suit and absorbing it.

They all had diving suits that have the feet, flippers, and head of the normal penguin suit. The suits match each of the girl's main colors and has a white belly. (However, in Wiess' case, her suit has a silver color just to prevent confusion.)
"So… diving suits but in penguin form?" Ruby asked.
"I can definitely see that." Yang said as they looked at another sign.
"By wearing these suits, you have the ability of breathing underwater so you don't have to go up for air or drown like a wet and dumb blue hedgehog looking for air bubbles."
"A blue hedgehog…?" Weiss asked.
"Must be a resident of the Mushroom Kingdom." Blake said as they dove right on in.
World 3-2: Just Keep Swimming!
BGM: Dire Dire Docks (Super Mario 64/DS)
"This is so pretty!" Ruby exclaimed, as they were looking around while swimming underwater.
"We can talk underwater too?" Yang asked.
"Sweet." Blake said as they swam around, seeing a few Cheep Cheeps and a few Bloopers minding their own business.
As they were swimming, Blake turned her head to see the same Big Bertha who spotted her and did the 'I'm watching you' gesture as Blake shuddered and looked the other way as they dove to the ocean floor and seeing some clams and Urchins.
"Cute!" Ruby exclaimed.
"…Yeah, they're okay." Weiss muttered as they kept swimming when they noticed a Sushi coming straight for them.
"Is that a shark?!" Blake exclaimed.
"AAAH! GO AWAY!" Ruby shouted, looking away and unleashing an ice ball at the Sushi, freezing it solid and it floated up to the surface.
"…How did you do that?!" Yang asked.
"Um… I guess these Penguin Diving Suits have ice powers?" Ruby shrugged.
"Let me try." Yang said, extending her hand and freezing an unsuspecting Blooper as it floated up to the top. "Sweet!"
Blake tried it out on a Deep Cheep as it floated up as well. "Cool." She said as Weiss did the same on an Urchin.
"Now this is what I'm talking about!" Weiss grinned as they swam around, seeing some very friendly dolphins while swimming around as they noticed a few Fishbones in the area and then they noticed some fishing hooks.
"Wonder who's fishing?" Ruby wondered and curiously swam up to see a fishing boat, and the Koopa Bros were sitting there.
"Caught any of the girls?" Red asked.
"Nope." Green.
"Nada." Yellow.
"Zilch." Black.
"Well, keep fishing! They gotta be here somewhere!" Red ordered as Ruby swam back down.
"The Koopa Bros."
"Are they following us?" Weiss asked.
"They probably are." Ruby said.
"Heheheh, this will teach 'em." Yang smirked as she grabbed a hook and placed it on Red's shoe and gently yanked it.
"Oh! Oh! I got a bite!" Yellow exclaimed and reeled it in, hearing a big splash in the process as he shrugged it off and pulled it up, only to see Red as his eyes widened.
"…Do I look like a Cheep Cheep to you?!"
"Sorry!"
All four girls laughed at this. "Nice one!" Ruby exclaimed, high fiving Yang as they proceeded to swim a little more until reaching a warp pipe as they went in and saw the flag pole in front of them after coming out as Yang took it.
"Let's go!" Yang said as they all took off.

At Bowser's Castle…
BGM: Bowser's Castle (Paper Mario: The Thousand Year Door)
"Lord Bowser…" A voice said as Bowser turned his head to see General Guy approaching him.
"General Guy… you might be aware of some team called Team RWBY coming over to try and save Peach and the Mario Bros."
"I have."
"I want you to put a stop to them before they screw everything over."
"I will." General Guy nodded. "In fact… do you happen to have a King Bill Blaster?"
"I might have one… why?"
"Because we're going to need more than just simple Bullet Bills of what I plan to do."
Bowser chuckled. "Do what you have to do."
"Thank you." He bowed and walked off.
Bowser smirked. "Let's see them get through this one." He chuckled.
End BGM
At Beacon…
Jaune was happily eating his lunch as he felt a tug on his leg and looked down to see Zwei whining. "No, not now. You can have your own lunch." He said.
Zwei growled. He wasn't going to let up so easily as he hopped up on the table and grabbed Jaune's sandwich as he took off with it. "Hey!" Jaune exclaimed as he ran after him as they ran around the entire school again as he hid behind Velvet's legs.
"Hmm?" Velvet turned her head. "What are you doing, you silly dog?"
"Come back here, you little sandwich thief!" Jaune exclaimed as Zwei barked and took off running again, as he rounded a corner.
As Jaune rounded the same corner, Zwei was gone. "Zwei? Zwei! Where are you?!"
As he was looking, Ren approached him. "Jaune."
"Yes?"
"It might be best if you let Zwei eat the piece of sandwich. After all, he didn't eat this morning."
"I could've sworn he did…" Jaune muttered. "Still, I was enjoying that…"
Ren chuckled. "I'm sure the dog would've enjoyed it too."
On the roof…
"What'd you score, buddy?" Sun asked as Zwei put down the sandwich and barked. "Sweet!" He grinned as he cut the sandwich in half and gave half of it to Zwei.
Zwei barked happily and licked him.
"My thoughts exactly, this is by far the best sandwich I've ever eaten."
The two proceeded to eat the sandwich as Zwei happily jumped into his lap while eating.
The Cheep Cheep kissing Weiss was an opportunity that I couldn't just pass up.
