Music was playing loudly as a familiar mouse in sorceror's clothing used some sort of magic to move lights all over the area as Jexi's group appeared to see this.
"Wow. He's very good at that!" Nami said.
As Mickey kept doing magic, clouds gathered above as a familiar Spellican came out and attacked them, knocking them out. When they awoke, they found themselves in a familiar room in a tower.
"Are we...back in Yen Sid's tower? But this looks off somehow?" Sora said.
They looked around to see Mickey asleep in a chair as he waved his fingers like in the previous vision.
"This hat, these clothes…. Is this based off of Fantasia?" Rainbow said.
"That majestic orchestra of amazing music and visuals?! Somebody pinch me!" Rarity said.
"Fantasia? Whats that?" Luffy asked.
"Its only one of the most famous musical performances of all time." Rarity said.
"And this must be one of the most famous songs, the Sorcerer's Apprentice." Rainbow said.
"Then what's with that?" Ichigo asked pointing to a music stand surrounded with a dark aura.
"Something must be possessing it, and I got a hunch its the one that got away." Sora said striking it before being pushed back.
"Gosh, is that a keyblade? Who are you apprentice to?" a familiar voice said in their minds. "I'm Mickey, the sorceror's apprentice."
"Apprentice? Then...we're in a world where the king was still in training." Sora said. "I'm Sora. Mickey, what can we do to save you?"
"Thank you, Sora. But there's nothing you can do. A monster has possessed the music and he's releasing darkness that stops anyone from going in there to fight him." Mickey said.
"Is there any way we can get in?" Aelita asked.
"Its simple, if you can get a Sound Idea. It lies within this." Mickey said as another music stand appeared with bright music surrounding it. But be cautious, between those clefs and notes are monsters. Not as powerful as that one, but still very scary."
"We can handle em. Lets go, guys!" Rainbow said as they advanced into an area with many clouds all around them and rainbows too.
"Wait, I remember this score. We're in a Pastoral Symphony." Rarity said.
"Which put in what exactly?" Yosuke asked.
"Its a charming piece with many fields and clouds and such. Its quite beautiful. If I'm right, we need to keep going until we reach the glen, then the fields. The Sound Idea should be in the fields." Rarity said.
As they proceeded through the clouds and rode the rainbows, the music played beautifully with each step. The group enjoyed it as they made it to the glen where the music softened a bit as they moved across the long glen before arriving in the fields with ease. At the end of the long long field, a music score that floated awaited there for them. They got the score.
"So easily you sink into the depths of slumber." a voice said as they saw the young Xehanort approach them.
"Hey, we cant help but listen to this, its really nice." Rainbow said.
"I dont think thats what he mean." Sora said.
"Beautiful world, isn't it? Almost like a dream." Xehanort said.
"Why are you following me?" Sora asked.
"You still haven't caught on? Or are you just assuming that this is all part of your little 'test'? I'm not part of the dream, and if you thought I was, then you are softer than they say." Xehanort said.
"What?" Sora asked.
"But, this will all be over soon." Xehanort said walking away.
"Just who are you people?" Sora asked.
"Sleep on and we will meet again." Xehanort said disappearing in a flurry of flower petals.
Upon returning to the tower, they presented the Sound Idea to the dark music.
"I can just tell you guys found a Sound Idea. Well, i guess we should try and put it to work." Mickey said.
Sora began conducting with his keyblade when as he did, a second sound idea appeared in the air as it played in harmony before dispelling the darkness.
"Whoa. They joined to make more powerful music." Brook said. "Simply amazing."
"Well, two forces are better than one. Thanks again, Riku." Sora said.
"Now lets get in there and get out runaway dream eater!" Kanji said as they dashed to the musical score, now free of the darkness, and appearing the area that was there before going into the tower. It was there the Spellican flew past them as it began riding on a musical score.
"Now we take you out, for good!" Luffy said.
(Cue-Sorceror's Apprentice from Fantasia)
The group on the score of music as they chased after the Spellican who countered with magical spells of its own.
"So you want to play that way, hm?" Rarity said as she used her geode to create gem arrows. Using her bow, she fired each one to cancel a spell before hitting the Spellican's broom, making it shake.
"Got you!" Sora said taking advantage and hitting the spelican, finishing it off.
"Couldnt get away this time, huh you big birdie?" Teddie said.
Back in the room, Mickey's spirit returned to its body as Mickey awoke. He jumped happily before seeing the hat and taking it off and then approaching the others. "Thanks, Sora. Don't know what I woulda done without you all." he said extending a hand.
Sora smiled as they shook hands. Mickey then realized something. "Oh no! The water! I'm in beg trouble if I don't fetch it! See ya guys real soon." Mickey said grabbing two buckets.
"Never a dull moment, huh guys?" Ichigo said as they keyhole appeared in the air in reaction to the glow of the hat Mickey was wearing.
"Never is. What about you, sora?" Sunset asked.
"Never." he said aiming his keyblade. "And I wouldn't ask for the opposite."
A light shined after locking it.
