Turtle Power! YH catches up with the voices behind Donatello (Rob Paulsen), Michelangelo (Greg Cipes), and Raphael (Sean Astin) of Nickelodeon's "Teenage Mutant Ninja Turtles" at Comic-Con and we quickly begin to realize how perfect for their respective roles they truly are! Greg tells us about his life-long dream to be a TMNT, Sean shares some vocal warmups, and then the nunchucks come out! Hosted by Nikki Novak (@nikkinovak).
