(A/a) means any animal you mutate into

With a small skip in your step, Y/N was walking back from the store. You had decided to buy Donnie a new phone so that he could mess around with the new technology to calm him after Raph had gone on a breaking spree earlier in the week.
'That turtle needs to calm his shell' you thought with a roll of your eyes as you thought of the memory. It was weird, in a matter of seconds it was like people just vanished. The usual busy New York was practically silent; not that you hated it, it meant you could easily slip into the sewers but it still made your guard be put up.

With each step you took, you felt as though someone was following you and it just grew and grew. You rushed to get to the manhole cover and began to climb down.
Suddenly, it was as if time stood still, a thick goo was poured over you from the rooftops above, causing you to fall and black out.

*A few hours later*

You woke up feeling strange. As you opened up your eyes, you saw Donnie staring down at you with wide eyes.
"What happened?" you ask, lifting your hand to your head when you let out a small scream.
"I-I found you... Shredder... He... I'm so sorry YN" Donnie apologised as he held up a mirror so you could see that you had been mutated into a(n) (A/a) .
You couldn't hold it back as tears fell slowly, Donnie wrapped his arms and held you as you cried.
"I still love you" he whispered.

I'm so sorry this has taken forever to do! I know this chapter sucks and I'll try to improve as time goes on!
I hope you enjoy and I love feedback!
