World 3-3: Unagi-Infested Waters
BGM: Beach Bowl Galaxy (Super Mario Galaxy)
"You know, I think I prefer the beach over the desert." Weiss said as they were walking around the beach, seeing a few Toads and friendly Shy Guys playing in the water.
"Because it's tropical?" Yang asked.
"That and the fact that we don't have to deal with an angry sun." Weiss said, looking up to see the sun shining down on them.
"I can agree to that… and it's not so hot either." Blake said as they saw a pool of water in front of them and dove on in, they saw a few Cheep Cheeps swimming around until they got out from the other side and walked around where they noticed a sign.
"Warning, Unagi-Infested Waters. Swim at your own risk… and may the Mushroom Gods have mercy on your soul that the Porcupuffer doesn't spot you." The sign read.
"What's a Unagi…?" Ruby asked.
"I bet it's just a really scary looking shark." Yang said, as Ruby paled up.
"Or it could be a monstrous squid with large tentacles!" Weiss said, making Ruby pale up even more.
"…Or it could be another cat-eating fish." Blake said. "…That eats humans too." She said, causing Ruby to lose her entire color… and strangely enough, the Penguin Diving Suit lost its color as well.
"Uh, Ruby… are you okay?" Yang asked.
"Yeah… just… suddenly not feeling so hot."
"Oh relax, we're just messing with you." Yang grinned as they dove on in.

BGM: Beach Bowl Galaxy –Underwater- (Super Mario Galaxy)
As they swam around, they quickly realized that a Unagi was just a small Eel. "Oh… it's just an eel." Weiss said.
"Hmm… I wonder if they taste good…" Blake wondered as she swam over and quickly took a bite as the Unagi roared in surprise and glared at her before electrocuting her as she coughed out smoke as the Unagi swam away… but not before slapping her with its tail and taking off. "Okay… not edible."
"No duh, Sherlock." Weiss said as they swam around, seeing a bunch of Unagi as they were completely unaware of a certain Porcupuffer that spotted them and sneakily approached them.
"What I want to know is what the hell is a Porcupuffer." Yang said.
"Perhaps it's a normal Cheep Cheep with an attitude." Ruby pointed out.
"Yeah right… like that would happen… then again, there was a huge one that swallowed up Blake." Weiss said as Blake shuddered.
"Never again…"
As they were swimming, several Bloopers and Blooper Nannies saw them and chased after them, as the four were completely unaware… in fact, a Cheep Chomp spotted them too and went after them as well.
When they all grouped together, they looked at each other and nodded as they swam up… and then the Bloopers and Blooper Nannies ambushed the four, surrounding them in a circle.
"What the…?!" Ruby exclaimed as they got ready to fight, and then adding insult to injury, the Cheep Chomp and the Porcupuffer got in the circle and started to swim around them in a menacing sort of way.
"Leave us alone!" Weiss ordered, as they all launched ice balls, but the two fish avoided it as some unfortunate Bloopers and Blooper Nannies took the blow as the Cheep Chomp and the Porcupuffer got in front of each other and then the Porcupuffer slammed into them and the Cheep Chomp proceeded to eat them alive.
…Well, that's what happened in their heads.
In reality, the Porcupuffer got ready to ram them when they quickly dove down and then the Porcupuffer was still swimming really fast… and got chomped on by the Cheep Chomp. Cheep Chomp's eyes widened and tried to shake it out, but unfortunately, the Porcupuffer was a little too big and his tooth was stuck inside the Porcupuffer, and since the top of him was spiky, that really had to hurt for the Cheep Chomp.
As they were struggling, the Bloopers sweatdropped at this while Team RWBY was laughing… and then something very menacing and humongous swam past them… and then the next thing they knew, a gigantic Unagi chomped down on the two of them, eating them instantly… and all of them paled at the humongous Unagi.
"Sooo… swim like hell?" Yang asked.
"YEP!" They all yelled as they took off while the Bloopers quickly swam away, but the gigantic Unagi was more interested in the girls and chased after them, as a few Cheep Cheeps were in front of them and saw the gigantic Unagi as they turned around and took off, including a few Sushi, Deep Cheeps and friendly dolphins.
The girls quickly swam up to the surface while all the other aquatic life got the hell out of there as the Mega Unagi was closing in on them, and then when they got to the surface, they quickly swam to the beach where a few curious Skeeters looked at them in curiosity before the Unagi breached for the surface… and crushed the poor Skeeters in the process.
As they reached the land, the Mega Unagi glared at them before swimming back into the watery depths.

"I think…I saw…my life flashing before my eyes…" Ruby panted.
"Same here…" Yang said as they noticed the flagpole right next to them as Blake took it and then they noticed a warp pipe that lead back into the ocean.
"Oh great…" Weiss muttered as they took the Warp Pipe… and into a sunken castle.
World 3-4: An Undead Shark's Domain
BGM: Abyssal Ruins (Pokemon Black/White)
"Are we in some sort of underwater castle?" Yang asked.
"Oh! Maybe we're in that lost city of Atlantis that Nora talked about at one point!" Ruby exclaimed, her eyes sparkling. "Nora's gonna be so jealous!"
"…I don't think we're there, you dolt!" Weiss said as they swam around, seeing the various seaweed and moss covered in the walls, and seeing several Bonefish in the process.
"This could be another one of Bowser's castles… I think." Blake said, seeing a few paintings of an ancient civilization. "Or it could be an ancient castle from long ago."
"Hmm, a beach castle… oh, I'd go swimming every day!" Ruby giggled as they swam around as they got in a humongous room and looked around.
Yang spotted something in the corner of her eye and went over to some ancient text. "Hmm… it says here that a humongous war broke out and is the main cause for the castle to be sunk in the bottom of the ocean."
"How did a war cause a castle to sink in the middle of the ocean?" Weiss asked.
"Well, given how this kingdom is… I wouldn't be surprised if they used something that changed the landscape of this place." Blake said.
"Oh, it says here that this castle was ruled by King Bowser the First who despised the Emperor of the Mushroom Kingdom and it lead to a great war until they used an underwater bomb that caused this part of the land to explode and sink the castle along with King Bowser the First… or who is now called Dry Bowser." Yang read.
"Dry Bowser… okay…?" Ruby raised an eyebrow at this.
Then Yang read the next note as she raised an eyebrow at this. "During an underwater exploration of Seventeen Toads, only three made it out alive due to a menacing species called Kingfin. Kingfin is extraordinarily dangerous and will eat you alive within seconds. Whatever you do, do not anger it, otherwise you are dead."
Unaware of them, a certain bony shark was right behind them.
"Oh, here's another note. It says here that Koopa Shells are its weakness, due to a great battle with it several years ago, but Kingfin killed the brave men and women who tried to get rid of the menace." Yang said.
"Well, let's just hope we don't run into that th-" A deep growl was heard, interrupting Weiss. "-ing…" She gulped. "Ruby… was that your stomach?"
"I wish it was…" Ruby said as they slowly turned their heads to see Kingfin who roared at them.
BGM: Bouldergeist/Kingfin (Super Mario Galaxy)
"Oh god, it's a bony shark!" Blake exclaimed.
"What do we do?!" Weiss exclaimed.
"We fight! That's what we do!" Ruby said as they proceeded to fight the bony shark. Kingfin swam in front of them but they quickly dispersed to confuse is as they all pelted it with ice balls, but that didn't seem to do much harm to the creature until Yang noticed a treasure chest on the ground as she swam down and saw a Koopa Shell in it as she opened it up.
"Aha!" She grinned as she pulled it out as she swam over to it as Kingfin was trying to fight them and actually used his tail to try and stun them, but luckily, they were fast enough to avoid it.
"Is ice not effective against this thing?!" Weiss wondered.
"Hey, fish guts!" Yang got its attention. "EAT KOOPA SHELL!" She yelled as she threw it, hitting him right in the jaw as it roared in agony, and then it whistled, calling in its Bonefish friends to help them as a few of them locked cannons at them and fired Torpedo Teds at them.
"Whoa!" Ruby exclaimed as they quickly avoided them as the Bonefish tried to snap at them while the Torpedo Teds circled around them as Kingfin tried to attack them as they tried to avoid all of them until a Torpedo Ted quickly circled around Ruby as Kingfin was right behind her while WBY was attempting to shake off the Bonefish and Torpedo Teds.
As Kingfin went for the kill, so did the Torpedo Ted as Ruby quickly dove underwater and then Kingfin chomped down, getting a mouthful of Torpedo Ted and… well… exploded as it roared in agony as Ruby threw a shell when she dove down, seeing a lot of cracks around it.
Perhaps one more will dispose of it!
Weiss quickly was corned to a wall as she quickly swam up as a Torpedo Ted went a little too fast and smacked into the wall, revealing a Blue Spiny Koopa Shell from behind the wall… and this had wings. "Oh?" She curiously looked at it before picking it up and throwing it at Kingfin, but Kingfin noticed this and dove down, as the Blue Shell went past him.
"Drat!" She growled as they quickly tried to find another way to dispose of the shark, none of them finding any Koopa Shells.
However, unaware of any of them, the Blue Shell screeched to a halt before it hit a wall and it turned around, looking directly at Kingfin as it proceeded to go straight for Kingfin and to their amazement, the Blue Shell circled above Kingfin.
"Um… Mr. Shark? You got a little something… above you." Ruby said as Kingfin curiously looked up and saw the Blue Shell was coming down really fast as Kingfin's eyes widened and tried to escape… but it was no use as it eventually caught up to it and made a spectacular explosion that caused Kingfin to explode into pieces.
End BGM
"Wahoo! We did it!" Ruby cheered.
"I didn't think I had it in me…" Weiss said, unaware of the Blue Shell's mechanics as they swam up to the surface and got out as they found a few bushes as they proceeded to get out of their diving suits and their swimming suits and into their clothes once again.
"Well, that was fun." Yang said.
"Yeah. Let's keep going." Ruby said as they proceeded to walk along the beach as they saw a forest in front of them.
Behind them, a few Airships came up from behind them and General Guy was in the lead. "Alright men, let's take 'em out!" He ordered as a few Shy Guys armed the King Bill Blaster. "Ready… aim… FIRE!" He ordered as the King Bill was shot out.
"Did you hear something?" Yang asked as suddenly, the King Bill landed near them and was embedded n the ground.
"What the heck?" Ruby asked as they looked at it curiously before it lit up and exploded, as they all screamed and was launched into the jungle.
"Direct hit!" A Shy Guy Commander exclaimed. "Well… sort of."
"Either way, they were launched in the jungle." General Guy said and then pulled out a walkie talkie. "Lord Bowser, the deed has been done."
"Have they been killed?" Bowser asked.
"Well, I assume so. They were launched into DK Jungle."
"Make sure they're dead!"
"Right away sir." General Guy nodded as a Shy Guy whispered in his ear. "Oh?"
"What is it, General Guy?"
"Your Nastiness, a few Shy Guys just picked up on an Underwater Castle in the ocean."
"Underwater Castle? Never heard of such a thing."
"Well, they said it holds the remains of your ancestor, King Bowser the First."
"…I'll send an exploration party. I want to learn more about him and figure out WHY I share a name with that guy. Meanwhile, I want you and your team to go into DK Jungle and see if they're alive."
"Yes sir." General Guy nodded as they docked the Airships. "Alright men, let's move!" He ordered as they proceeded to go into the DK Jungle.
With a KO'd Ruby…
Ruby was lying in the middle of the jungle, separated from her team as a big familiar ape came down from a tree and noticed Ruby, curiously poking her before picking her up and taking her to a treehouse.
At Beacon…
"Ah… this feels good to kick back and relax…" Jaune said, lying on a beach chair with Ren as Nora and Pyrrha were in a pool, swimming around and playfully splashing each other.
Meanwhile, Zwei managed to find a bone and found a perfect spot to bury it as he started digging furiously as dirt was flying everywhere until he put the bone in the hole and barked happily, then walked away.
Unfortunately, the dirt just so happened to land on Jaune and Ren as both of the girls saw this and immediately dug them out.
"Talk about being at the wrong place at the wrong time." Ren said.
"Or maybe he just wants to bury us alive…" Jaune muttered.
"You're all dirty… in you go!" Nora pushed the two in and she and Pyrrha dove on in again while Zwei started to rest near the pool, sleeping soundly and dreaming about that bone he just buried.
Oh ho ho, the plot thickens!
