To The Worldwalker: I've seen the Master Fortress fight on Youtube. Looks quite a challenge.

World Castle Map (Super Mario 3D World)

"Mama mia..." Mario said as he was looking up.

"Geez, how tall is this thing?" Marisa wondered.

"Might as well find out." Erza said as they walked straight ahead.

World Castle-5: Two Towers and a Trap

Simmering Lava Lake (Super Mario 3D World)

A Thwomp slammed down on the ground in front of them as soon as they entered the tower. "Yeesh! That's one way to greet people..." Pit said as they soon went under the Thwomp after it went up and then they went on a rising platform.

As soon as they got up, Meiling kicked a Parabone away as they saw another Thwomp. "Oh great...this is gonna take a while..." Sora said.

Reisen noticed a platform above them as she curiously flew over to investigate, then walking around a corner to see a Green Star and a stamp. "Hey!" She exclaimed as she picked them up and then looked up. "I wonder..." She flew up as she was greeted by three Magikoopas.

"You...you're the one that killed our leader!" A Magikoopa exclaimed.

"Uh...that was Marisa, not me." She said.

"QUIET! We will avenge Kamek!" He exclaimed.

"Oi vey..." Reisen muttered as she raised her finger at the three of them. "I guess I'll deal with you." She said.

"TAKE THIS!" A Magikoopa exclaimed, as they all fired magic at her, but she fired three bullets on magic that was aimed for her and then she jumped up and fired a bullet at one, then fired at another and right before she landed, she fired right at the last Magikoopa's wand, making it go flying into the lava below.

"H-have mercy!" He exclaimed, raising his hands up. "I surrender!"

"You can't give up that easily." She said, firing directly at him as he fell to the lava below, and then a Green Star appeared in front of her as she took it. "That's the end of them." She said as she noticed the others walking up to her.

"Uh, how did you...?" Natsu wondered.

"Oh, I decided to wander around and collect two Green Stars and a stamp." She replied.

"I was wondering where you went." Eirin said as they went on a gondola and went to the next tower.

"Another one?" Pit asked. "How many towers are there?"

"Too many, I imagine." Reimu said.

"Actually, there are only two." FLUDD said.

"Okay, two." Reimu corrected as they walked in as they saw tons of Fizzlits in the area. "Uh, what are these?"

"Fizzlits." Mario replied. "We encountered them at Switchboard Falls when you were busy racing."

"They were racing?" Erza asked.

"Oh come on! You didn't invite me?" Pit asked. "Man, I should've stayed for the celebration of the Mushroom Kingdom...but no, Lady Palutena and Viridi were insistent that I should go." He sighed.

"Well, what are you gonna do about it?" Gray shrugged as they easily wiped out any Fizzlit in the way while Captain Toad found a secret passageway as he curiously went in and finding a Green Star.

"Booyah!" He exclaimed as he took it and then came back.

"Found a Green Star?" Toadette asked.

"Yep!" Captain Toad smiled as they kept on going.

As they kept climbing, Erza had a troubled look on her face. "Something wrong?" Reimu asked.

"I don't know why...but I have a bad feeling." She muttered. "Doesn't it seem...too easy that we're facing little opposition in this tower?"

"Come to think of it, it does seem easy." Reimu said. "Anyone else having this same feeling?"

"I am." Eirin said.

"Me." Luigi said.

"Same." Sakuya said.

"I'm not alone." Remilia muttered.

"I am too." Nitori said and then looked at FLUDD. "Do you got anything?"

"I'm picking up some sort of...immense power." FLUDD said. "And it's at the top of this tower." He said as they got to the top.

"I don't see anything..." Reimu said.

"Hmm..." Natsu saw the last Key Coin in front of them. "Well, might as well grab it." He said as he picked it up.

"Wait, Natsu!" Erza exclaimed...but it was too late. Suddenly, the whole place rumbled as dark purple smoke came down from above.

"What is THAT?!" Luigi exclaimed.

"Purple smoke." FLUDD said. "Very deadly."

No Time to Think! (Kingdom Hearts)

"Quick! Let's get out of here!" Reimu exclaimed as they nodded and then ran down the tower with the smoke closing in on them until they all got out and the purple smoke spilled out and landed in the lava below.

"Well, that was too close..." Luigi said.

"Um, guys...? We're not out of the woods yet." Lucy said.

"What makes you say that?" Marisa asked, and then they noticed the lava was rising. "OH CRAP!"

"We need to get to higher ground!" Xion exclaimed.

"What higher ground? The tower is covered in toxic smoke!" Pit exclaimed. "This is not how I wanted to go down...I want to see my little kid be born! I don't want to be a fried angel!"

"Wait...what did you just say?" Marisa asked, looking at Pit. "Did you say...your little kid?"

"Yeah."

"YOU DID NOT DO WHAT I THINK YOU JUST DID TO VIRIDI!" Luigi yelled.

"Hey! I'm married! It happens all the time, Luigi! When you get married, I'm pretty sure you're going to get Daisy pregnant!"

"I'm not ready to be a dad!"

"Will you both shut up! We need to find higher ground!" Toadette exclaimed.

"WELL WE'RE DEAD! I DON'T SEE ANY HIGH GROUND!" Blue Toad exclaimed, and suddenly...they all lit up and disappeared before the lava could touch their feet.

"...Are we dead?" Luigi asked.

"No..." Pit replied as they looked at a Flagpole near them. "We're next to the flagpole."

"Sweet!" Sora exclaimed as Marisa took the flagpole, and then they saw a warp pipe in front of them as they went in.

World Castle-6: Rammerhead Territory

Cave (Super Mario 3D World)

They all screamed on the way down and then they landed in water. "Does it HAVE to be water?!" Marisa exclaimed.

"Mario...I think she's turning into Sonic the Hedgehog..." Pit whispered.

"No kidding." He agreed.

"I heard that!" She exclaimed.

Nitori sighed and then manipulated the water. "There, you can breathe underwater. Happy?"

Erza shook her head. "I know you had bad luck with water in the past, but this is getting ridiculous."

"Not my fault that King Fin knocked the living crap out of me..." She muttered as they dived in.

As they were swimming around, they saw the first Green Star in a small opening as Mario took it as they then kept swimming around...however, Erza's armor was kind of slowing her down. "Man...I didn't think this armor would slow me down underwater..." She muttered. "I guess I have to change my armor." She said. "REQUIP!"

"What's she changing into now?" Luigi asked as they all looked to see that she's in her Sea Empress Armor...and cue anime nosebleeds from all the guys.

A Blooper swam by and noticed Erza, as its eyes widened and kept looking at her, not seeing where it was going and then smacked RIGHT into a wall, knocking itself out.

"That is a lot of blood..." FLUDD said.

"Wow..." Reimu said. "That's...wow."

One major revival later...

Wendy panted. "Man...I think I did a little too much..." She muttered while Eirin sighed.

"No kidding..." Xion said. "I think I need to recharge my Curaga spell..." She said as they kept on walking.

"I never thought I'd die from a major nosebleed..." Pit said. "What a way to go..."

"Namine is gonna kill me..." Roxas muttered.

"And Kairi." Sora said as they kept swimming along, and as they did, they saw a few Rammerheads. "FLUDD?"

"These sea creatures are called Rammerheads. They are very rare." FLUDD said. "The only things that can kill them are Invincibility Stars."

"What about when I go mentally unstable?" Flandre asked.

"According to my data, not even a mentally unstable vampire can kill them."

"WHAT?!" Flandre yelled. "That's no fun!"

Pit sighed with relief. "Oh thank goodness...I thought I was going to go through that nightmare again..." He muttered as they swam around while avoiding the small Rammerheads, but Kaguya managed to grab a Green Star behind a Rammerhead's tail and then they kept on going.

"How far is this place underwater?" Sora asked.

"I think we've been here for quite a while, I imagine." Erza said, still in her Sea Empress armor as they still swam around until they saw the final Green Star in a clear pipe surrounded by spiked balls.

"Okay, how are we going to get that?" Happy wondered.

"Leave it to me." Lucy said, who STILL had the Fire Flower still active as she swam over it and then threw two fireballs to destroy them. "There we go." She said after she came out of the other end with the Green Star.

They continued to swim on and then discovering a lot of Rammerheads with a stamp in the middle of the area. "Oh great..." Pit muttered.

"STOPZA!" Roxas yelled, stopping the Rammerheads. "That should do it." He said as he took the stamp and then they swam to the warp pipe in front of them, and then they went in.

As they came out, they saw the Flagpole in front of them. "Oh thank goodness...I was about to go crazy in there..." Marisa muttered as Reimu looked at her with a raised eyebrow as Erza took it while changing into her regular armor, then they went onward.

I got nothing to say, really...
