You and your high school class are going down to a science lab to do field research on genetic mutations. After about an hour, the instructor tells everyone to go explore and have fun, so you decide to figure out where some of the other mutants were, considering you hadn't seen many and most were just cats with three eyes or dogs with two tails.

As you turn a corner, you see four turtles chained by their arms feet and necks to a pushed in segment of the wall. Unlike the other experiments, these four looked far more human, which you found unsettling.
