Finally, a proper trailer for the Teenage Mutant Ninja Turtles mash-up, Turtles Forever, has been released on the web. We’ve shown you the leaked scene which features some voice changes in Leonardo’s voice (like the old cartoon) and the awesomely upgraded animation.

However, now you can see a tubular new montage trailer that puts together several scenes of the 1980’s turtles, the 2003 turtles, and the Mirage comics turtles, along with all their friends! Have a look at the “trailer” below!

Turtles Forever was originally planned to release in theaters as a one time event for the 25th anniversary “Shell-ebration,” however some problems arose that caused that plan to fall through.

Do not fret though, Turtles Forever is being broadcast on Saturday, November 21, 2009 at 10 a.m. on The CW4Kids TV. Be sure not to miss it, otherwise it might be a while before we see it pop up on DVD.
