Of course, the other Sound idea was brought by Riku and the others, but this is how they got thiers.
Riku and the others appeared at the entrance to the tower, where the place was flooded.
"Of course this is Fantasia, the Sorcerer's apprentice. As the Ultimate Musician Ibuki, youd eat this stuff up, being into this right?" Hope said.
"I'm into Heavy Metal mainly, but this is rocking too." Ibuki said.
"Its coming from upstairs." Riku said as they ran up stairs to see a sleeping Mickey waving his fingers as brooms marched with water buckets in their hands.
"And now the whole plot of the song. Mickey goes to sleep, things get outta control, and the brooms do Mickeys job too well and flood the tower." Hope said.
"That's right, but how did you know?" mickeys voice came.
"I...just...do." Hope said. "And we can help you stop this."
"Yeah. My name is Riku." Riku said.
"Riku huh? I don't know how but we can be good friends helping each other out alot someday." Mickey said.
"Oh you dont know the half of it." Hope said. "Anyway, i suppose the source of you still asleep is that?" Hope asked pointing to the darkness possessed scoresheet.
"Yes. But you're going to need a sound idea to unlock it." Mickey said before a score sheet appeared.
Riku pointed his keyblade at the score sheet, transporting the group into a small wooded area with glowing flowers that shined in moonlight.
"Wait, this area...this is from the Nutcracker Suite." Ibuki said.
"So what's the story with this one?" Bubbles asked.
"Its something to do with changing seasons. We keep going, we'll go to a Golden Wood and then a Snowgleam Wood, where the Sound Idea thing is." Ibuki said.
"Well, good enough for us, I guess." Riku said.
As they marched onward, beautiful music played the further they went as it seemed like the seasons changed with each step they would take. It changed from a warm summer to a breezy fall before ending in a cool winter where the group soon came across the sound idea. But as soon as they got it, darkness overtook them as they fell into a deep area with black mountains and lava streams that were like rivers.
"DId this happen in the original song?" Hiyoko asked.
"No. This is A Night on Bald Mountain!" Ibuki shouted.
As they fell, they flew for a moment before landing on land before seeing the Young Xehanort waiting for them.
"Oh come on, you just had to step in and change up the song, didnt you?" Ibuki said.
"So you were waiting for me." Riku said.
"Yes, I have. The boy chosen by the keyblade, Riku." Xehanort said.
"What?" Riku asked.
"It was yours first, wasn't it? But you succumbed to the darkness you could not control, and your prize, the keyblade, passed on to Sora. Your mistakes always end up being other peoples problems." Xehanort said.
"Maybe so, but I'm here to change all of that." Riku said.
"Once again, you have performed predictably. Although on a grander scale than I imagined." Xehanort said.
"If you're feeling so chatty, let's skip to where you reveal what this is all about." Riku said.
"I don't know how you and that boy in blue did it, but you both have found ways to trap the darkness inside your hearts. And boys who are immune to darkness are of no use to us." Xehanort said.
"Trap darkness?" Titanica asked Hope.
'Yeah. Its a trick I learned from watching Sora and Riku fight. When I jab my hand into a person's heart to purify them, I absorb the darkness into my own heart and turn it into light. Its just how my purification works." Hope said.
"Well, at least there's some good news for the both of us." Riku said.
"Your abyss awaits." Xehanort said as fire erupted behind him as he vanished as a large black demon with wings rose from the volcano.
"Well that doesnt look good…" Hope said.
"Alright you guys, we have a new target. Lets beat that thing into next week!" Ibuki said.
"Were going to fight that thing?!" Hikoko asked.
"Its called Chernabog, not a thing one, and two, we dont have much of a choice, now try to keep up and not get burned by lava!" Hope said.
"Lets rock this Musical Orchestra!" Ibuki said as her guitars presence changed the music to a whole new track.
(Cue-Dragon Force: Through the Fire and Flames)
Chernabog just stood on his mountain as he summoned evil spirits to do his bidding against the squad.
"Lets do this!" Hope said as they fought through the spirits as they flew right at Chernabog in order to combat the evil he was summoning. He was not giving an inch as he summoned fire to attack the group as they countered to the best of their ability.
"Come on. You guys can do it!" Ibuki said.
The squad was on the ropes as Chernabog had the upper hand. But before it could land the finishing blow, the sun slowly began to rise as Chernabog shielded its face and eyes as it soon faded away in the suns light.
"Well, there's something that can be on everyone's side." Hope smiled as they vanished.
They returned to the tower where Riku began conducting the music. But as he did, a second score appeared as it began dispelling the darkness. After that, the water vanished as Mickey awoke.
"Gosh. It worked. But what happened?" Mickey asked.
"Sora." Riku said smiling.
"Sora? Funny, just hearing that name kinda makes me wanna smile." Mickey said.
"Yeah. That's how he is." Riku said.
"Whaddya know? Riku and Sora. The sound ideas you two found joined together to create an even more powerful music." Mickey said.
"Sora can find the brightest part in anything and pull off miracles like there's nothing to it. Its pretty hard not to smile around him." Riku said.
"Wow. No wonder the music sounded like so much fun." Mickey said. "But I bet he's got all of you to thank for that. Its like you have pieces of each other. You're hearts are always in tune so they're free to sing together. I hope I can join in that someday." he said extending a hand.
Riku took and shook it. "You will. Trust me." Riku said.
After Mickey left, the keyhole soon appeared. Riku then locked it.
Meanwhile at the real tower…
It was an eerie silence with the five inside that tower. Mickey soon broke the silence.
"Master Yen Sid, do ya think they'll be able to do it?" Mickey asked.
"Hmm. Its clear you cannot teach a cat to bark. But Merlin and the three good fairies are aiding them in a place thats more temporally flexible. My hope is that they can at least learn to wield them. They both have fire, but it all depends on how strongly it burns." Yen Sid said.
"Oh. What about Sora and Riku?" Mickey asked.
"If you are asking on the assumption that Xehanort knew what we were doing, he would have needed to have been there. Back in the very place and time the Destiny Islands were lost to darkness. Otherwise, they would be beyond his reach." Yen Sid said.
"Gosh, do you really think Xehanort would have planned that far in advance?" Mickey asked.
"No, I do not believe he would." Yen Sid said.
"But what if he did what Sora and Riku did and jumped through time?" Goofy asked.
"For that to work, a version of himself would have to exist at both source and destination. Not even Xehanort can transport his body through vast reaches of time." Yen Sid said.
Aqua then realized something." But Xehanort did give up his body. There was a version of him that possessed Riku." Aqua said.
"No! It cannot be? Could he have been that cunning? Possess that kind of foresight?" Yen Sid asked in shock.
"If its all right with you, can me and Aqua go help out?" Mickey asked.
"How? You cannot enter the world of a dream? Where would you go?" Yen Sid asked.
"If my hunch is right, they can't stay in the dream world forever. Eventually, they're gonna reappear somewhere we can reach them. And we can guess the place. Follow the hearts and you will find the way. That is something you told me, Aqua." Mickey said.
Aqua then began to get a call on her comm. "Hope?" Aqua asked.
"No. This is Annette. Something impossible has happened." Annette said. "The bodies of your friends...they're gone!"
"What?!" Aqua said.
"I thought this room was safe, but somehow someone broke in and took all of them. I don't know who, but ...get back you!" Annette said before it went silent.
"Annette? Annette!" Aqua shouted before a voice came on.
"Sorry. But dreamer girl can't come to the phone right now." a guys voice said. "And don't worry about color kid and baby blue. I'm taking good care of them."
"No… is that?" Mickey asked.
"Xigbar." Aqua said.
"Xigbair, I aint. I'm back Aqua, in my own man." the voice said.
"Right. Braig." Aqua growled. "What have you done with them?"
"Don't worry. I haven't hurt them...yet. But I am having the urge to shoot baby blues eyes out, cause you know...he beat me in the castle as a nobody." Braig said.
"Where are you taking them?" Mickey asked.
"Oh, I think you already know the answer to that. Remember where we all were. That place where nothing gathers." Braig said.
"The World that Never was." Aqua said.
"So if you got any brains, you'll come running to save em before something bad happens. Bubye." Braig said before they heard the comm get crushed.
"We have to go." Aqua said.
"Thinkin the same thing. Master?" Mickey asked.
"Go. This is no longer an exam. I cannot locate Sora, but I was able to locate Riku's presence." Yen Sid said.
"Thank you. I promise to bring them all back safe and sound." Mickey said.
