Leonardo, Donatello, Michaelangelo, and Raphael are back in an animated series that more closely follows the dark tone of the original comic books than did the comedy-driven 1980s version. With the help of Zen master Splinter (a mutated rat) and their human ally April O`Neil, the four ninja turtles battle New York City crime, their evil nemesis Shredder, and the mad scientist Baxter Stockman in a series of action-packed adventures. This volume continues the series with five more episodes.
