While Teenage Mutant Ninja Turtles 2 promises to bring fans the much anticipated first ever big screen appearance of favorite mutant characters Bebop and Rocksteady, Nickelodeon's animated Teenage Mutant Ninja Turtles TV series is beating them to the punch. The two classic villains are set to battle Leo, Mikey, Don and Raph on this Sunday's episode...And they have a new, improved look. We have a clip from the episode, which you can check out below.

J.B. Smoove, who kids surely won't known from his stellar work opposite Larry David on Curb Your Enthusiasm, will play Bebop in The Pig and The Rhino, while Fred Tatasciore is taking on the voice of Rocksteady. They'll both hit the small screen when brand-new episodes of Teenage Mutant Ninja Turtles return March 8, at 11:00 a.m. on Nickelodeon. In the action-packed episode, Donnie finishes a new batch of retro-mutagen, in hopes of saving Karai, while the Turtles find themselves hunted by Shredder's new vengeful henchmen, Bebop and Rocksteady.
