Nickelodeon's Teenage Mutant Ninja Turtles begins as the turtles emerge from their hidden lair in the sewers for the very first time, ready to confront the wondrous and hostile world of New York City and face enemies more dangerous and pizza more delicious than anything they could have imagined. Funnier and with more Ninjutsu than ever before, the show will explore the companionship of four teenage brothers learning to rely on themselves and one another as they unravel the mystery of their existence and grow to become the heroes in a half-shell that they are destined to be.
