Chapter 2: When Worlds collide

Narriator: Last time on "New Dimensions" an evil gem from a different world freed himself from its prison and unleashed his powers to the four worlds of our heroes! Sonic and his friends were landed in the White Space, where not only meet their Boom counterparts, but also Johnny once again. Now they have to find the reason of the events. But a yellow sponge and his friends were also in the scene.

The gang is still confused about the other gang. Boom Amy tries to reach them, but Sticks holds her back.

Sticks: Be careful, maybe these creatures are DANGEROUS!!

Sonic: Or they need some help.

Johnny: How? Again, we don't know about them!

Dukey: İt's like the first encounter with Sonic. Hah, good memories...

Dukey remembers back, how he and Johnny met Sonic and Tails for the first time.

Johnny: Wait. ThIs hedgehog and the fox. (tries to wake them up) Hello?

Dukey: (narrating) I thought, this won't work again. And it was.

Dukey: It's no use, Johnny. We must help these poor blue and yellow animals.

Johnny: But we don't know about them. (looked to Dukey, who was not so happy and then sighs) Fine. To the lab!

The yellow sponge interrupted the memory.

???: Hello? How about us?

Johnny: Huh? (looked to the sponge) Oh.

Cream: Who are you?

The gang introduced themselves as SpongeBob, Patrick, Sandy and Squidward.

SpongeBob: My name is SpongeBob SquarePants. And these are my favorite buddies, Patrick, Sandy and Squidward.

Sandy: Hello.

Squidward: Oh boy... (facepalms)

Susan: Squidward looks like, he's not happy about it.

Squidward: It's about these stupid morons!! (points at SpongeBob and Patrick)

Patrick: Haha! Nice joke!

Squidward: (angry) IT'S NOT A JOKE!!!!

Johnny: Sheesh, what's wrong with him?

Dukey: Nevermind.

Sandy: Who are you guys, anyway?

Sonic: I'm Sonic. Sonic the Hedgehog! And these are my friends: Tails, Knuckles, Amy, Cream, Cheese and also the so called "Boom" version of myself.

Boom Sonic: Don't forget about my friends. They have the same names as our different versions, except Sticks. (points at Sticks)

Sticks: Hmmm....

Johnny: Also I'm Johnny Test. These are my sisters, Susan and Mary...

Dukey: ...and also his best friend and dog, Dukey!

Spongebob, Patrick and Squidward: Aaaaah!

Sandy: A talking dog? Cool!

???: Arrr. What's going on here?

Spongebob: Mr. Krabs?

True, Mr. Krabs appeared to the group.

Mr. Krabs: Spongebob! Squidward! Who are these people?

Spongebob: These are our new friends. Right, Patrick? Patrick?

Patrick is somewhat in love with Amy...

Patrick: Sweeeeeet!

Amy: Eew!

Boom Amy: I hate to say, but she's right. (disgusted)

Johnny: Okay, this gets really awkward...

Susan: Yep...

Johnny went to Sticks.


Sticks: İ don't trust you.

Dukey: But there is no need to attack him.

Sandy: Yeah, I think you two have to learn, to trust each other.

Suddenly the ground shakes.

Patrick and Boom Knuckles: AAAAHH! Earthquake!

Boom Tails: No. I think, something is wrong here...

Boom Sonic: Well, time to investigate!

The Boom crew ran to the cause of the shake.

Sonic: Guys, we have to go too!

SpongeBob: I'm not really sure... Maybe there is a ghost! (in fear)

Sandy: Come on, SpongeBob! Ghosts don't exist!

The ground shakes again.

Patrick tries to hold Amy.

Amy: Hey, get off me, Patrick!

Patrick: İ can't!

Johnny and Dukey tried to pull him away from Amy.

Dukey: Let her go!

Johnny: Get off!

They managed to pull Patrick away.

Cream: We don't have much time, guys.

Mary: She's right.

Johnny: Come on! What do we waiting for?

Sonic: Let's go!

The gang followed the Boom crew. Meanwhile, Eggman, as well with his minions were at the White space too.

Cubot: What happened?

Eggman: It seens, that a massive shockwave of dark energy caused a dimentional corruption and we all landed here.

???: Well, if isn't our old friend?

Eggman recognized the voice immediatley. It was Wacko with the rest.

Eggman: Wacko, old buddy! Nice to see you and your pals again!

But Eggman stepped of something, as he tried to reach them.

???: Ow!

Eggman rose his right foot and saw a creature underneath it. He pulled him out of his shoe. It was a little plankton.

???: Hey! Watch out, were you going!

Eggman: Sorry. I didn't know, that you were here.

Mr. Mittens: It's because, he is so tiny!

???: Silence!

Wacko: Couldn't you introduce yourself first?

???: My name is Plankton! I WILL RULE THE WORLD!! Hahahaha!

Dark Vegan: We have the same goal too. But we get stopped by our enemies.

???: Need help?

The rest turned to Modern Eggman.

Eggman: That was not from me!

They looked around and saw Boom Eggman.

Eggman: Is that myself?

Plankton: Hmmm.

Wacko: So, Eggman Nr. 2, what are you doing?

Boom Eggman: Allow me to demonstrate.

Boom Eggman showed to the villains a crystal.

Plankton: Wow.

Wacko: What is that?

Boom Eggman: This crystal contains a lot of power...

Eggman grins evilly, while the others are thinking.

Back to our heroes...
