The turtles and Lizzie were using the turtle blimp to get to TCRI

Raph: So do we even have a real plan here or are we just winging it for laughs?

Lizzie: Donnie said he has an idea

Donnie: It's all on the Mighty Mutanimals. First they break into TCRI then Doc Rockwell activates the portal.

Mikey: And then it's back to Dimension X! Yeah boy! I get to be smart again!

Lizzie: again?

Leo: we've been to dimension X before and Mikey learned pretty much everything about it

Mikey: you know I did!

Lizzie: that will be helpful

Raph: I know the plan It's the save millions of mutated New Yorkers part I don't get

Leo: Well Donnie's got his super Retro Mutagen stuff. That'll work. Uh right Donnie?

Donnie: Heck yeah! And once we change all the humans back Rockwell will hone in on us with the Kraang portal and theoretically teleport us all back to Earth! hopefully... Maybe...

Lizzie: did you bring more that that one canister of retro mutagen?

Donnie: no but it'll work!

Raph: yep we're doomed

Mikey: It's an awesome plan Raph. Dimension X, here we come!

Leo: I just hope the Mutanimals don't screw this up. If they can't get that portal open

Lizzie: right now we have to trust them

At that moment a portal to dimension X appeared

Mikey: Yes! They did it!

Leo: Unbelievable. You were right Lizzie

Lizzie: I usually am

Raph: Hoist the mizzenmast lads! This pirate ship's about to jack Dimension X!

Donnie: Ready your oxygen converters

The turtles and Lizzie put on oxygen converters so they could breathe in dimension X

Mikey: Booyakasha!

___________________________________

The five of them made it to Dimension X

Leo: Ok welcome back to dimension X

Lizzie: I don't know why but I already hate this place

Raph: you and me both

Mikey threw a smoke bomb and was now wearing the outfit he had on last time he was in dimension X

Mikey: Savage Mikey of Dimension X returns!

Raph: Again with the costumes?!

Lizzie: also why are you calling yourself savage mikey?

Mikey: I'm great at naming stuff so I gave myself a dimension X name!

Leo: Let's just go with it. Great Savage Mikey so where do you think the Kraang are keeping all those mutated humans?

Mikey: Hold on. I can sense them close by with my organic antenna... keep going this way!

Raph: You heard the man Donnie. Full speed ahead!

The turtles and Lizzie continue to look for the New Yorkers

Leo: so where are all the people? Feels like we've been searching forever

Lizzie: it's only been about 30 minutes

Raph: You got any idea where we're going Mikey, for real?

Mikey: Of course I do dude!

Suddenly a giant kraang worm attacked them

Mikey: But there are always surprises along the way

Lizzie: you just had to say something!

Donnie: It's a Kraathatrogon!

The Kraathatrogon popped the blimps balloon causing the turtles and Lizzie to fall on a flouting kraang island

Mikey: I think I broke my brain...

Raph: Ha what brain? I'm taking this freaky space worm down myself!

He tired to attack the kraang worm but was pushed off the island

Raph: AHHH!!!

Lizzie: Raph!

Raph landed back on the ground

Lizzie: what the?! Do physics work differently here?

Donnie: yes!

Mikey: I got this Donnie!

Mikey threw smoke bombs at the kraang worms butt face

Mikey: FYI guys Kraang worms weak spot are their butt faces. Got that?

Lizzie: first off yes and second everything will just keep getting weirder isn't it?

Mikey: you know it Liz!

Donnie saw a kraang lair

Donnie: guys look!

Everyone else saw it to

Leo: This just keeps getting worse and worse and worse

Mikey: Let me guess. The humans that got Kraangatized have been turned into servants and are mining energy crystals for the Kraang.

Lizzie: wow that's exactly what they're doing

Leo: Mikey you never cease to amaze me.

Mikey: I'm sweet like that dude.

Raph: So we figure out a way to turn the humans back

Donnie: And then the Mutanimals figure out a way to bring us all home

Leo: It doesn't seem possible

Lizzie: I'm sure it is. We've done the impossible before and I'm sure they can

Mikey: exactly Lizzie! it's the Mighty Mutanimals the operative word being mighty. They got it all under control!

Suddenly the portal back to earth closed

Lizzie: No!

Raph: looks like your not usually right after all

Leo: not the time Raph! It looks like the Kraang have human hybrids on three islands

Raph: Those islands are huge! I mean how are we gonna turn all those mutants back into people?

Donnie: You forget Raph. We just need to find a massive amount of Mutagen and convert it into Retro Mutagen

Raph: is that all? A massive amount of Mutagen?

Lizzie: this is dimension X! There has to be enough mutagen here

Mikey pointed at a technodrome

Mikey: I bet that thing has a ton of Mutagen inside of it!

Leo: A technodrome? Mikey-

Mikey: Don't say it because I know. I'm a genius

Leo: I was gonna say you're crazy! Steal a technodrome?!

Lizzie: even if we did do you even know how to pilot one?!

Raph: not only that but how would we even get there? The blimp's a wreck

Donnie: Or we could borrow one of those stealth ships parked over on the closest island. Just saying

Raph: This is so crazy I'm starting to like this plan

Lizzie: I've been in one of those before

Raph: you mean back when you helped the kraang deliver a shipment of mutagen that spilled all over new york?

Lizzie: I'm not that kind of person anymore!

Mikey: All right guys. Stay frosty and keep quiet and all those other things Leo likes to say

___________________________________

The five of them use the low gravity to jump all the way to the other island and snuck inside the stealth ship

Mikey: Get this baby moving Donnie!

Lizzie: we don't have much time!

Donnie: I'm starting it. I'm starting it!

Donnie used the ship's controls to turn it on

Leo: So you really know how to fly this thing?

Donnie: Um sort of I kinda did it before. Not exactly...

Lizzie: oh for gods sake I'll fly this thing! Like I said before I saw the kraang it up close!

Mikey: no need Lizzie! Let me handle this!

Mikey took the controls and was able to fly the stealth ship easily

Raph: So what are we gonna do when we reach that technodrome? Anyone thought that far ahead?

Donnie: Um not really?

Lizzie: wait what?! You said we turn the mutagen into retro mutagen!

Donnie: I did! But I need to find out how!

___________________________________

The turtles and Lizzie made it to the technodrome

Raph: We made it! Wow that was easy

Mikey: uh Raph?

They all saw a bunch of kraang guarding a gigantic tube of mutagen

Raph: Ah Kraang

Lizzie: you should've learned by now to never say that

Leo: Attack!

The five of them attacked the kraang

Mikey: Leo I'm leader in Dimension X!

Lizzie cut a kraang in half with her scythe

Lizzie: it doesn't matter who's in charge!

Mikey: yes it dose!

He stole two blasters and took out the kraang easily

Raph: Mikey that was amazing!

Mikey: Dimension X plus years of video games equals Mikey awesomeness!

Lizzie: well i guess I was wrong before

Leo: time to get this thing moving! Donnie what have we got?

Donnie tooked at the controls

Donnie: Good news. It looks like we have access to their mutagen supply through this fuel tube. Not only do they use Mutagen to terraform they use it to power the ship. We've got a massive supply!

Mikey: Nice! Let's save New York!

Human's were shown on the screen

Leo: We have a visual on the human hybrids Donnie we need that portal ready to go

Lizzie: did you figure out a will you turn all the mutagen into retro mutagen?

Donnie: almost... got it!

Donnie added the retro mutagen into the tube and all of it became retro mutagen but then the technodrome stopped moving

Leo: Something's wrong. What's going on Donnie?! Report!

Lizzie: report?

Donnie: I told you the technodrome runs on Mutagen. The engines just can't take Retro-Mutagen Captain!

Lizzie: captain? Whatever mikey what do we do?

Mikey pressed a bunch of bottles on the controls

Mikey: I just need to alter the ship's fuel convertors, tweak the quantum defiblitrons, and voila!

The technodrome's colors changed from pink to orange and was working again

Raph: Mikey you're-

Mikey: A genius I know

Raph: Wasting time! Get this thing moving! We have to save the humans already!

Lizzie heard the kraang banging on the locked door

Lizzie: Donnie do something!

Leo: we need that portal open!

Donnie used the T-phone to call Dr. Rockwell

Donnie: come in Dr. Rockwell!

Dr. Rockwell (on the T-phone): Donatello we are back online!

The portal back to earth opened again

Dr. Rockwell: 30 seconds until we teleport you home

Lizzie: ready the retro mutagen!

Leo and Mikey: FIRE!

Donnie activated the retro mutagen turning the humans back to normal and then we're immediately teleported back to earth

Donnie: We did it! We turned a multidimensional transmat device into a mass-displacement teleporter!

Raph: I have no idea what you just said but hooray?

Lizzie: can anyone translate what Donnie just said?

Mikey: That's how we're going home. Teleportation y'all!

Leo: Just like space heroes!

The turtles and Lizzie were teleported home right when the technodrome blew up

___________________________________

The five of them landed on a roof of a building in New York

Lizzie: we're alive! Yes!

Leo: we did it! Somehow we did it!

Lizzie hugged Leo

Lizzie: I have a feeling we won't have to worry about the kraang for while

Leo: your right about that Lizzie

Mikey: We're the best! Go Ninja! Go Ninja go!

Donnie: Finally everything is gonna go back to normal. Well as normal as this city can get

Lizzie: what about my mom? She might still be hurt

Raph: and the Mighty Mutanimals?

the Mighty Mutanimals were standing right behind them

Leatherhead: What about us?

Mikey: Leatherhead! My big green buddy!

Mikey hugged leatherhead

Leatherhead: We made it my friend

Donnie: Looks like our plan worked Doctor

Rockwell: Yes and teleporting the Kraang back to Dimension X was a stroke of genius and Elizabeth your skills against the kraang were very impressive

Lizzie: thank you Rockwell

Raph: You gotta admit Leo. We couldn't have done this without Slash and his team.

Leo: You did great Slash and I'm sorry I doubted you. Everyone deserves a second chance.

Lizzie: just like me. I've made many mistakes but making the right choices is what really counts

Slash: I just tried to model myself after the best leader I ever knew Leonardo

Leo: today's It's time to celebrate!

All: Booyakasha!
