One-"Uhhhhhh, what happened? And why are my closes making me itch?"

Numbuh One opens his eyes and sees the sun shining and when he gets up, he's surprised to be on top of a hill.

One-"Huh? Wasn't I suppose to be in the tree house? Unless the light explosion from that weird stone has something to do with this!"

He looks around, walks up to the edge of the hill and sees a huge and beautiful emerald colour forest full of trees of all kinds, flowers and some more hills.

One-"Just, where am I?"

That is when he hears a yawning sound and it sounded like Numbuh Two's.

One-"Numbuh Two? Is that you?"

He turns around and behind him, he sees something huge on the ground and it is now getting up. A huge brown half human, half bear and it's wearing the same clothes as Numbuh Two does and some dark brown gloves, which is what caught Numbuh One's attention.

Bear-"(Yawning in Numbuh Two's voice) Maaaaaaaan, what time is it?"

Numbuh One slowly walks up to the bear.

One-"Numbuh Two?"

Two-"Oh morning Numbuh One! (turns to Numbuh One and…) AK, who are you?"

One-"Huh? Who are you referring to?"

Two-"(After hearing what he said) Numbuh One? Is that really you?"

One-"Well of course it's me Numbuh Two, what do you think?"

A blue vein sticks out from his head

Two-"Uh, well, you're a hedgehog!"

One-"(confused) A what???"

Two-"Yeah! Umm, (takes out his tool box and shows him a mirror) Look!"

Numbuh One looks at the mirror and…

One-"(Freaked out) OH MY GOD, I AM A HEDGEHOG!!!"

Two-"Told ya."

Nigel saw that he is now a half human, half Hedgehog of the same colour of his shirt, narrow green eyes behind his sunglasses, pointy ears, a huge hair of spines curved back, white gloves and his old clothes, but they were making him itch.

One-"(scratching himself) OW, Numbuh Two? Does your clothes make you itch?"

Two-"(also scratching himself) Yeah, in fact, they do! I say we ditch them!"

One-"(horrified) You mean, go nude???"

Two-"Yeah, something wrong about it?"

One-"Everything, Numbuh Two."

Two-"Hey, if we are animals, no one will see a thing!"

One-"If you say so."

And so, they take of all of they're clothes and the itching's gone. By removing they're clothes, it reviled that Numbuh One had Skin colour arms and a plain belly. Numbuh Two had white hair coming from the belly up to the chest and a new belt around the waist with a golden buckle. Numbuh One remained the sunglasses and Numbuh Two remained the pilot helmet.

One-"Ah, much better."

Two-"Uh, Numbuh One? What do you think it could have happened to us?"

One-"I don't know, all I remember was the light explosion from that stone and here we are, as a hedgehog and a bear."

Two-"Hey uh Numbuh One? (shows the stone in his hand) Look!"

One-"The stone? How did you get it?"

Two-"I guess it was taken here to."

One-"Hmmm, that stone is really supernatural, we need to find out more about it! But first we must find the others."

Two-"(Putting the stone in his tool box) Aye aye!

Numbuh Four's voice-"(cring) HEEEELLLLPPP!!!"

Two-"That sounded like Numbuh Four!"

One-"Come on, he might be in trouble!"

And they both ran down the hill into the forest.

Numbuh Four's voice-"HHHHEEEELLLLPPPP!!!"

One-"HANG ON NUMBUH FOUR!!! WERE COMING!!!"

And they reached the river. There was a bridge and they started to cross it.

Numbuh Four's voice-"(from the river) HEY, A LITTLE HELP OVER HERE?"

Numbuh's One and Two looked down to the river and there was a Half human, half Echidna of the same colour of Wally's hair and the same clothes as him. He was standing ona rock in the middle of the river and surrounded by piranha robots.

One-"Numbuh Four?"

Four-"(looks up to the red hedgehog and the brown bear) Numbuh One? Numbuh Two?"

Two-"Don't worry! We'll get you out of there, one way or another!"

An unknown voice-"Now that's what I'm talking about!"

One, Two and Four-"Huh?"

The three operatives look at where the voice come from and are surprised to see a 15-year-old blue half human, half hedgehog with narrow green eyes, pointy ears, a huge hair of spines curved back, a plain belly, skin coloured arms, white gloves and red snickers with one white stripe in each of them with golden buckles. The hedgehog had a smirk on his face.

Blue Hedgehog-"So your friend is in trouble, huh? Let me take care of that!"

And to they're shock, the Hedgehog jumped from the bridge and turned into a spiny spinning ball and crashed into the piranha robots, destroying them. After destring the last one, the hedgehog back flip jumped to the rock where Numbuh Four was, picked him up and jumped back to the bridge.

Blue hedgehog-"You okay, little buddy?"

Four-"Yeah, I'm Okay. Thanks, I guess."

Meanwhile, Nigel and Hoagie were shocked on what he had done.

One-"Did you see what he did? That strange Teenage Hedgehog saved Numbuh Four!"

Two-"I know, did you see the way he took out those piranha robots?"

Numbuh Four walks up to them.

Four-"All right Numbuh One, what is going on here?"

One-"Um, perhaps that blue hedgehog can explain."

Blue Hedgehog-"Ahem."

And they look to where the voice came and there was the blue hedgehog laying on the beam of the bridge.

Blue Hedgehog-"The Hedgehog here has a name, and it's Sonic, Sonic the Hedgehog!"

One-"Sonic the Hedgehog?"

Sonic-"That's my name!"

They remain silent for a few seconds.

One-"All right, I am Numbuh One of the Kids Next Door and these are my fellow Kids Next Door operatives: Numbuhs Two and Four. At a few moments, we had arrived at our tree house back from our mission and we found this strange white diamond shaped stone that created this light explosion that had taken us all to this forest. We had appeared to have be unconscious after that explosion and when we wake up, here we are as a hedgehog, a bear and a echidna. Now, we require to know our exact location and why are we now in these new half human, half animal forms just like you."

Then he notices that Sonic had fallen asleep after all that conversation.

One-"HEEELLLLLLOOOOOOO!!!"

Sonic-"(wakes up) Huh?"

One-"Did you even hear a word I said?"

Sonic-"Yeah I did, you just talk too much there."

One-"(falls over, anime style)"

Sonic-"Anyway, you said something about a white diamond shaped stone, do you have it?"

One-"Affirmative, Numbuh Two?"

Two-"Aye, aye!"

Numbuh Two takes out his tool box and takes out the stone.

Sonic looks directly at the stone and gasps.

Sonic-"I knew it!"

One-"You know about this stone?"

Sonic-"Heck I do! It's one of the seven Chaos Emeralds!"

One, Two and Four-"Chaos Emeralds?"

Four-"What the crud is this about the Chaos Emeralds?"

Sonic-"Well…"

"The seven Chaos Emeralds are mystical gemstones that posses unlimited power. No one knows they're origin, but they are linked to many ancient races. They're power depends on the user, they can be used to power-up machines and unlock special abilities, for those who can harness they're power. And if someone collects all seven, he or she will gain the power to do whatever they want!"

One, Two and Four-"WOW!"

One-"But how can such puny Emeralds carry so much power?"

Sonic-"Sorry, but I don't even know that. As where you are, you are know on planet Mobius and you have been changed into Mobius."

Two-"Well, that makes sense now, because everything looks different and somehow similar to Earth."

Four-"If Kuki is here, I just hope she's OK."

Sonic-"A girl you like?"

And Numbuh Four blushes making Numbuh Two burst into a laughter.

Four-"(nervously) T…That's not true, she just, uh…owns me a coater."

Sonic-"(sarcastic) Right."

One-"Come on team, we've got to find the others!"

Two and Four-"Yes Numbuh One!"

Sonic-"You might as well let me come with you. After all, your on a different planet, right?"

Four-"Sorry, no teenagers allowed."

One-"Ok."

Four-"What?"

One-"Listen, we are on another planet and Sonic here seems to know this planet a lot better then we do, so we are going to need all the help we need to find Numbuhs Three and Five."

Two-"He's right Numbuh Four."

Four-"Okay, but I still don't like it."

Two-"Hey, don't say that, besides he saved your life, remember?"

Four-"(sigh) yeah your right."

One-"All right Sonic, you take the lead."

Sonic-"All right, but you better hang on to me Okay?"

One-"Uh, Okay, do what he said guys."

And they all hanged to Sonic's arms and shoulders.

Sonic-"All right here we go."

And all the sudden, they disappeared in a blue stream of light. It was Sonic running at supersonic speed and the operatives are doing they're best to hang on to him.
