Sonic and his two friends were brought into the emergency room wondering about the accident that had changed their form. There were no other clothes around for now so Makato had them wear lab coats for the time being so that they could cover up their nudity; though they had only gloves and shoes to compensate which was little.

Sonic didn't mind standing up while Tails sat in the hospital bed and Knuckles went to the chair all of them to the doctors explanations while the four non animal teens also wanted to know what's going on so they stayed in the room with them.

"This is the first time ever in my experience for anything like this to happen." Dr. Makato was intrigued. "Animals turned into my Vocaloid creations why no one would've heard such a thing."

"I believe that when we inhaled your chemicals they transformed us like when you used it to shape the Vocaloids their form it pretty much did the same for us." Tails thought up.

"But look at us we still have the things from when we were animals, just look at my fists I still have my spiked claws and your two tails remain as is you and Sonics ears." Knuckles said.

"The chemicals were meant to give life to a lifeless body. It was suppose to give the body what we were intending my guess is that because you weren't human yet you still had form it instead changed your physical looks but it couldn't 100% make you human thus some of your traits were left in when you were animals." Makato theorized.

"Does this mean we still have our powers?" Sonic asked.

"You should although we may need to see if you have kept those too." Makato said.

"Wait a second if they had taken the same chemical we took wouldn't they be able to sing too?" Len realized.

"Yeah it was also the same thing that made us be able to sing could it also do that to them?" Miku followed.

"Those are good questions I think since we're here right now we should try and see the effects." Said Makato.

"Now wait a second I'm not a singer and neither are my friends, sorry but even if I was given the voice I never once tried singing at least not in this universe (AKA Sonic Underground XD)." Sonic relented.

"Oh come on Sonic it won't be that bad nothing worse could come out of it we're just trying it out." Tails encouraged.

"That's right it's a simple harmless test nothing more. Before we go any further though I think maybe you need some clothes." Makato informed making the three animal humans realize they still don't have actual clothes.

Into the recording room the former hedgehog, echidna, and fox were all dressed up and ready to sing behind the glass while wearing headphones next to a hanging microphone with the podium holding pages of musical lyrics in front of them.

"Hey Tails how's my unifom?" Len pressed the communication button from behind the glass as Tails was dressed in the young Vocaloids males summer sleeveless school uniform.

"It fits well except I had to cut holes from behind to fit my tails in, sorry." Tails apologized.

"It's fine I got more anyway." Len forgave.

Luka then pressed. "Be sure not to do anything wrong with Gakupos clothes."

Knuckles was dressed in Gakupo's black sleeved dress shirt and pants and his reaction to it was. "I don't care as long as they fit and if he does get mad I'll beat him up."

"I heard that." Gakupo said in a bit of annoyance. "I know they're our guest but I was still using the room for my next song."

"You don't even have a concert yet so don't complain." Luka said smartly.

Miku then use the button next. "Hey Sonic how's Kaito's shirt and pants?"

Sonic was wearing Kaitos Blue T-shirt and brown pants.

"I can tell blue was definitely his color luckily." Sonic complimented.

"Yeah I figured blue matches you so I thought Kaito's clothes were perfect." Miku agreed.

Dr. Makato decided to wrap things up so he used the button last to instruct them.

"Now Sonic, Tails, and Knuckles all three of you read the words written on those pages, you each have one so try to obtain the voice any way you can. All you need to do is read the words and let your voice follow that is all it is to singing."

Sonic identified the top of the Lyrics and found the name of the song

"Open Your Heart." Sonic observed. "Well here goes I'll start."

Sonic cleared his throat then let his voice go to match the lyrics.

"Thunder, rain, and lightning." He started off simply.

"Danger, water rising clamour, sirens wailing, It's such a bad sign." Tails followed but was no better.

"Shadows of dark creatures, steel clouds floating in the air, people run for shelter, what's gonna happen to us!?" Knuckles of course didn't bring anything up either as his voice was downplayed.

Everyone in the control room didn't really find the singing as good as they were expecting.

All three of them then sang together

"All the steps we take, all the moves we make, all the pain at stake"
"I see the chaos for everyone who are we what can we do"
"You and i are same in the way that we have our own styles that we won't change"

They couldn't capture the same singing talent as the Vocaloids did; their singing wasn't even amateur they sounded closer to talking as their voices were either not fully released or they didn't know how to place the certain pitches.

"They don't know how to sing their voices aren't having the feeling." Luka said.

Sonic, Tails, and Knuckles were still trying to get the hang of it. "Yours is filled with evil and mine's not there is no way I can lose"

"Is this really their first time singing?" Len said stupefied.

"I think maybe they need our help." Miku suggested then headed for the entrance out of the control room and into the recording room with Rin and Luka following her.

Sonic and his friends then stopped their singing when they got a surprise visit from the three female teens.

"Here let me help you." Miku lent a hand.

"Miku I'm sorry but singing isn't something I ever found myself doing." Sonic reluctantly disagreed.

"Trust me I was made to sing and I know you can have it in you to do it." Miku then gently grabbed both of Sonics gloved hands. "Look at me." She instructed.

Sonic then obeyed and looked into her young and beautiful face which he started to realize more each time he was near her.

"Sing with me and follow my voice." Miku said softly then closed her eyes.

Rin and Luka were also doing the same thing with Rin holding Tails hand and allowing him to look at her. "Follow me too Tails."

Luka tried to hold with Knuckles but he pulled back. "Let's just do it without the holding hands." Knuckles relented.

"Fine I don't even want to touch those pointed fists anyway." Luka agreed angrily.

Back with Miku the experienced teen slowly started off by calmly inhaling then with a low release she let her voice flow through with an Opera styled vocal. "Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.

Sonic was a bit off but followed anyway. "Aaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hhh."

"Did you feel it?" Miku asked.

"I kind of did somewhere in my voice I think I can feel my voice go along." Sonic answered.

Miku then continued releasing slightly louder than before. "Haaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhh hhhhhhhhhhhhhhhhhhh."

Rin then taught Tails the same way. "Follow my voice , keep on going until you've found the level where your ability to release your voice lie."

"Okay." Tails listened.

Rin then performed. "Haaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hhhhhhhhh."

Luka didn't bother instructing so she got it on with and Knuckles had to follow as best he could. "Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh."

After taking the time to let their animal ears hear the sound of the Vocaloids females all three of them then those their eyes and did the same thing they were told to.

Sonic: "Aaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhh."

Tails: "Aaaaaaaaaaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhhhh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh."

Knuckles: "Haaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh."

The voices were heard for minutes but ended shortly after with the girls finishing first letting the three off to own their own voices. Sonic, Tails, and Knuckles slowed down their howling then stopped completely after feeling much of it.

"Were you able to feel your voice." Rin asked Tails.

"This is the coolest thing that's ever happened to me, I actually think I can sing." Tails said happily.

"Thanks it felt good." Knuckles said to Luka.

"You don't have to act so tough just because you don't think singing is man enough for you." Luka joked.

"I think I'll give it another try with the mic." Sonic went back to the microphone then tried it again.

"Can't hold on much longer; but I will never let go!"

Tails also wanted to continue. "I know it's a one way track; tell me now how long this will last!"

Knuckles went with them to finish the song. "I'm not gonna think this way; nor will I count on others
Close my eyes and feel it burn."

Tails: "Now I see what I've gotta do!"

Sonic: "Open your heart, it's gonna be all right!"

"Yes they did it." Makato said happily as the testing was a success.

"Who are they? Did you make more you never told us you were going to?" Gakupo asked the doctor.

"You'll know about it soon enough Gakupo." Len told him for now.

Miku, Luka, and Rin found them very good singers and loved how they used their voices now that they have the talent for them.

The three of them then sang together.

If it won't stop, there will be no future for us
Its heart is tied down by all the hate; gotta set him free

I know it's a one way track; tell me now how long this will last
Close my eyes and feel it burn; now I see what I've gotta do

Gotta open your heart dude

Open your heart, it's gonna be all right, yeah

Open your heart
Open your heart

Sonic finished: "Yeeeeeaaaaaah!"
