You were friends with the turtles ..and well a mutant too, but that didn't matter to any of you

You were helping gn the turtles in a fight against Rhazar and Fishface, who had a few foot bots with them. Raph was fighting Fishface while Leo was fighting foot bots. Donnie was trying, and struggling, to hack into the machine the Foot was using to mutate their soldiers. With Mikey fighting Rhazar with you while also making fun of Rhazar for being mutated twice.

Leo:Donnie, can you hurry it up!?

Donnie:I'm trying, but it's a whole TANK of mutagen!

Mikey was making fun of Rhazar with you as you jumped on top of Rhazar's back

Mikey: Bahaha! How do you even get mutated twice!?

You:Yeah Rhazar? How'd that happen? Try to take a bathhh~?

Rhazar was getting fed up with you both when he let out a growl and grabbed you in his claws

Rhazar:How about we see how you would look mutated twice?

Rhazar throws you up and you grab a board on the exposed ceiling above the mutagen tank

You try to hold on but fail falling into the tank as it glows brighter

Mikey, Leo, Raph, and Donnie:{USER}!!!

They watch as you crawl out falling to the ground as Rhazar, Fishface, and the foot bots run off. The turtles scoop you up taking you back to the lair

You wake up to Mikey beside you on the floor beside the couch, Donnie trying to figure out what happened, and Raph and Leo arguing trying to explain to Master Splinter what happened
