A new trailer for Nickelodeon’s upcoming CG-animated Teenage Mutant Ninja Turtles series has surfaced online. It’s actually the same trailer that was shown to folks who attended the TMNT panel at SDCC a few weekends ago. The new series is set to premiere on September 29th, and features the voices of Jason Biggs as Leonardo, Sean Astin as Raphael, Greg Cipes as Michelangelo and Rob Paulsen as Donatello.

If you missed out on the first trailer, watch it here.
