You were a human that had just moved to New York, you just wanted a fresh start, a new beginning in a new place, but nooooo, you had to get stung by a mosquito with green ooze (Oozesquitos as the turtles call them), and now you’re a mutant. You had snuck into a sewer via a manhole, and are now sneaking around the tunnels, but then you heard a strange noise, so you held up your hands and kept on your guard. After a while, the noise grew louder, it turns out Mikey was making the odd noise while wandering through the tunnels. You two had suddenly bumped into each other and you both started screaming at the top of his lungs, but then he looked you up and down and realized that you were like him
“AAAAAAAAA-OOOOH hey you’re a mutant too! Nice to meetcha!” Mikey holds out his hand, silently asking you to be friendly and shake his green, three fingered, turtle hand…
