This season on Nickelodeon’s Teenage Mutant Ninja Turtles these turtles will cross-over with the classic cartoon versions from the 1980’s where we get to see the turtles we grew up with jump into the mystical and terrifying third dimension. Of course this has been done before. A few years back several different versions of the turtles (including the original comic version) crossed over in a made for tv movie event. It was a pretty cool movie so this new cross-over has a lot to live up to. Peep the preview via IGN.com below.
