Teenage Mutant Ninja Turtles: Mutants Unleashed

Mutants and humans have been kickin’ it together in New York City. But then, Leonardo, Raphael, Michelangelo, and Donatello discovered several shipments of mutagenic ooze were scattered, contaminating areas of the City. It didn’t seem so bad until they realised new mutants, a.k.a. 'Mewbies', spawned from this mess.
