The new Teenage Mutant Ninja Turtles series is funnier and "ninja-ier" than ever before, as Nickelodeon reintroduces the wildly popular band of reptile brothers to a whole new generation of fans. The action comedy explores the camaraderie of four teenage brothers learning to rely on one another as they unravel the mystery of their existence and train to become the heroes they're destined to be. Traveling to the surface from their sewer lair home for the first time, the Turtles experience many "firsts," from battling evil denizens to eating their beloved pizza.
