To BlazingEdge: Actually, it was in the demo of Urban Legend in Limbo. It wasn't made up.

World 5 Map (Super Mario 3D World)

"I can finally live in peace." Mokou said. "Without her, it feels like I don't have to worry about her anymore."

"Yeah, we kinda get it." Youmu said.

"Hmm..." Lucy folded her arms. "You know...it's quiet without Kaguya...a little too quiet." She then glanced at Natsu and Gray.

"What?" Natsu asked.

"No matter what happens, you guys bond...even though you still butt heads to this day."

"She makes a good point." Gray said. "Heck, I'd be bored out of my mind if I didn't have someone to argue with."

"Ha! Same here." Natsu said.

"Are you saying I'd miss her?" Mokou asked. "There's no way I'm missing THAT hag!" She exclaimed.

It's only a matter of time... Reimu thought as they then noticed a warp pipe. "A warp pipe in the middle of nowhere?"

"Well, you know what they say..." Mario said. "If there's a pipe, there's gotta be something in it!" He exclaimed as he jumped in.

"Uh...no one says that, bro." Luigi told him.

"Well, he just did." Peach said as they all hopped in after him.

World 5-5: Bob-ombs Away!

Cave (Super Mario 3D World)

They landed and then they looked around. "I am detecting large amounts of POW Blocks in this area." FLUDD said.

"Whoa...that's a lot." Nitori said as they walked around, and then noticed a Bob-omb walking around.

"Oh look, it's a walking bomb." Marisa said as she picked it up, making it panic and light its fuse. "Oh stop panicking!" She told it as she threw it to a brick wall with a POW block on top, taking out a few Goombas as well.

"Nice throw." Reimu said.

"Thanks." Marisa smiled as they continued onward.

"I guess I don't need my headlamp for this." Captain Toad said as he noticed hanging lamps.

Mario picked up a Bob-omb and then threw it at a purple brick wall, revealing a Green Star. "Hey Mokou! I found one for you!"

"Hmm? Oh, okay." She said as she took it. Why do I suddenly feel empty? She thought as she walked away.

Flandre picked up a Bob-omb and just threw it at a wall, which hit a POW Block as it did some sort of chain reaction to more POW blocks, killing any Piranha Plant and then launching a Green Star out of a rabbit's hand. "Oh, hello!" She exclaimed as a stamp then fell near them.

"Well, that's quite the treasure we found." Remilia said.

"I guess." Flandre said as she picked up the stamp and then Mokou picked up the Green Star as they kept on walking.

"Hey Mokou, you feeling alright?" Sora asked.

"Uh...yeah." She nodded. Are you kidding? It's so boring without Kaguya! Sure we had our differences but... no...why am I feeling sad? That hag deserved every bit of it. She thought. ...Did she? She wondered as they went in a clear pipe, but Natsu and Happy went a different route since they saw an all familiar cloud, this time Gray and Erza followed them.

"Wow, that is a long line of POW Blocks." Reimu said.

Meiling saw a Bob-omb walking around and she looked at the POW Blocks. This is going to be epic. She thought as she walked over to it as she poked it. The Bob-omb curiously turned around...to get kicked in the face by her as it was launched straight to the POW Block and exploded. A Piranha Plant jawdropped at this before getting killed by the chain reaction. "Oh yeah!" She exclaimed.

"Well so much for picking it up." Xion shrugged.

"I wanted to throw it." Toadette sighed.

"You're not the only one." Nitori said as they walked ahead as Natsu, Happy, Gray and Erza landed near them with a Green Star in Gray's hand.

"Where'd you guys go?" Wendy asked.

"Someplace that wasn't in the clouds." Natsu replied.

"We were on this tile board thing." Happy said. "Once all the tiles were filled...it...looked like a 2D pixelated Mario."

Mario blinked. "I was pixelated back in the day?"

"Uh...I don't seem to remember that." Peach said.

"Neither do I." Captain Toad said as they went in the warp pipe.

Super Bell Hill (Super Mario 3D World)

They came out of the warp pipe to see a flagpole and a walking Bob-omb minding its own business as there was a brick wall. "Should we make some stairs?" Luigi wondered.

"Actually, I was thinking..." Youmu flew up and got on the top of the flagpole.

"Or we can do that." Luigi shrugged as they walked away.

World 5 Map

As they kept walking, Erza stopped walking. "Hmm?" Lucy turned her head. "What's wrong?"

"I smell something...familiar." Erza said. "It smells like..." She suddenly changed in her Flight armor. "Shortcake." She then ran off while accidentally knocking down Marisa, Blue Toad, Roxas and Mokou.

"OOOF!" Marisa yelled.

"Ow!" Blue Toad exclaimed.

Roxas shook his head and used Curaga. "What the heck was that about?"

"I dunno...but she seems really excited." Mokou said.

World 5-6: Let There be Cake!

Chainlink Charge (Super Mario 3D World)

"Holy crap..." Youmu blinked. "If Lady Yuyuko were here..." She blinked.

Reimu sweatdropped. "Let's not go there; I'm still amazed that she ate a whole freakin' galaxy."

"Wait, she ate a whole galaxy?!" Lucy exclaimed.

"It was all sweets. She had a little competition with Kirby." Marisa said, as Lucy sweatdropped while there was fear in her eyes.

"I think we found our Yuyuko." Gray said as they saw Erza putting cake on a plate.

"Where did she get the plate?" Wendy wondered as they walked around the area as they saw the first Green Star.

"There's the first one." Mokou said as she walked straight ahead.

"Wait." Mario stopped her. "I don't trust those platforms." He said as he looked at them. "Hmm..." He looked at them as he started to wave, move his foot, do all kinds of things, but they didn't activate as he then jumped, and then they activated.

"Those are called Flip-Swap Platforms. They activate when someone jumps." FLUDD said.

"Oh, I bet Kaguya would throw me off if she did that." She said and then sighed...a bit sad.

"You seem sad." Sakuya said.

"I'm not." She told her as she jumped on the platform and then casually walked over to the Green Star.

"I wonder if she enjoys her rivalry with Kaguya?" Flandre wondered.

"Probably." Remilia nodded as they kept walking while avoiding the fireballs coming from Fire Piranha Plants.

The ones who couldn't fly had to do a little timed platforming with the Flip-Swap, and it took a while because everyone kept falling to the ground and adding insult to injury, the Fire Piranha Plants were making fun of them, but eventually they got up.

"Oh, this is so good." Erza smiled, eating another piece of cake.

"How much cake did you have?!" Lucy exclaimed.

"Third slice." She smiled innocently before walking away.

"I swear, she loves this a bit too much." Gray said.

"Ya think?" Natsu asked as they kept walking around until they saw a Piranha Plant on it, as Natsu ran towards and punched it off, then he went in as Happy, Lucy and Wendy followed him.

Gray looked at the other side and then the Flip-Swap panels. "ICE MAKE: BRIDGE!" He yelled, making a bridge. "There we go." He said as the others walked on it while Mokou went ahead and took all the green coins to make the Green Star, as she then looked at it.

Kaguya... She thought as she had flashbacks of her. I hate you but...it feels so...lonely without you. She then looked to see Sora taking the flagpole. I'll be all the more miserable if I keep going. She then flew up. Kaguya...i'm coming. She thought and then flew off.

"Hmm? Where's she going?" Marisa wondered.

"Is she going back to Kaguya?" Reimu asked.

Back with Kaguya...

Sprawling Savanna (Super Mario 3D World)

The fire had died down, and a burned Kaguya was weakly getting up. The tape was burnt off but surprisingly, her clothes were still intact. "M-Mokou..." She muttered. "Why...would you do this?" She asked.

Second thoughts, Mokou?
