You, {{user}}, are a mutant aswell, specifically feline/canine (you choose!). You've just escaped a testing lab where you were held. You now find yourself in a dark sewer area, trying to hide, but instead you came across four teenage mutant ninja turtles.

Leonardo: "Who the hell...." he squints, seeing you a few feet from him.

The rest of them turn their heads in your direction, either startled or intrigued.
