A turtle for a dragon

Ninja in the lair

Leo made it back to the lair and gets out of the shell raiser with night ninja running out and hiding.

Night ninja: I did it. I'm at his home.

Night ninja walked around and was impressed of how the lair looked.

Night ninja: I gotta admit. They got good taste.

Something catches night ninja's attention and finds Leonardo talking to splinter.

Splinter: why were you not with your brothers Leonardo? I've been wondering where you were.

Leo: the pj masks called me and that they needed help.

Splinter: who are these pj masks?

Leo: their super heroes like us.

Splinter: they sound like children.

Leo: they are children sensei. And they were weirdly cool when they saw me.

Splinter: you revealed yourself to kids?!

Leo: three actually.

Splinter: you cannot see those pj masks again. They might reveal you.

Leo was in shock, not only that he couldn't go to tarabiscoville. But he couldn't see An Yu anymore.

Leo: *sigh* hai sensei.

Splinter: good, those kids might not be our friends.

Night ninja: you can say that again.

Night ninja leaves and sneaks into Donatello's lab.

Donnie: now if I'm correct, this should be able to work.

Donnie plugs the machine as it explodes.

Donnie: gah! Another failure.

Night ninja was about to leave when he saw the canister of mutagen. He used his ninja fingers to carefully lift the canister of the desk and into his hands.

Donnie: HEY! Where'd the mutagen go?!

Night ninja: mutagen huh? This could be useful.

Night ninja walks around and sees Raphael punching a dummy.

Raph: you like that huh? You like that?!

Night ninja: nope.

Night ninja kept on walking and sees Michelangelo.

Mikey: COWABUNGA!!

Mikey skates across the main room with Leo and splinter walking in.

Splinter: Michelangelo!

Mikey: sensei!

Mikey falls off his skateboard and splinter catches it.

Splinter: I told before not the skateboard in the lair.

Mikey: hai sensei.

Donnie: guys, do you know where the canister of mutagen ended up? I looked back and it's gone.

Leo: maybe you misplaced it.

Donnie: you could be right Leo. I'm gonna start searching. As he leaves to search his lab.

Splinter: remember Leonardo. Don't go back.

Leo: hai sensei.

Splinter leaves with Leo sneaking in the shell raiser and drives away back to tarabiscoville.

Night ninja: alright. Time to reveal the truth.

Splinter was meditating when night ninja placed a note.

Splinter: being a rat isn't bad, it is good.

Splinter opens his eyes and reads the note.

Splinter: WHAT?!?!?!?!💢💢💢

Donnie: was that sensei?

Raph: what's gotten on his beef?

Mikey: I hope it's not me.

Splinter: Leonardo is on a date!

Donnie: again?

Splinter: it's not miwa! She's An Yu, the guardian of mystery mountain! In tarabiscoville!

Turtles: WHAT?!?!

Donnie: that's he left? That little!💢

Raph: and he didn't say a word to us?! He's gonna get it!💢

Mikey: I didn't know he'd be this shy.

Splinter: we must get there! NOW!

Night ninja: *jumps in front of them* I can take you there.

Donnie: who are you?

Raph: he's infiltrating!

Night ninja: I am not infiltrating. I'm a ninja just like you guys. I come in peace.

Splinter: let him speak.

Night ninja: I know how to get to mystery mountain. Fallow me.

The turtles and splinter fallowed night ninja to the surface.

Night ninja: *whistles* ninjalinos!

A school bus drove in that looked like night ninja with big wheels.

Donnie: cool bus! Wait, you didn't steal that did you?

Night ninja: no, I found it at the junkyard. Get on.

The turtles and splinter got in the ninja bus as it drove to tarabiscoville. Night ninja was ready for the next step.
