Team Turtles is about to get a little bigger in this retro "Teenage Mutant Ninja Turtles" release! We're taking it all the way back to the shell-shocking action that brought the heroes in a half-shell and their human allies April O'Neil and Casey Jones together in the fight against evil! When four pet turtles were bathed in ooze, they began to mutate and became the "Teenage Mutant Ninja Turtles." Raised in New York City sewers by their foster father and martial-arts Master Splinter, Leonardo, Michelangelo, Donatello and Raphael wage war against crime. They stop evildoers in all forms, whether barbaric gangs, lowlife crooks, deranged cyborgs, or even the crime syndicate The Foot, led by their archrival, The Shredder.
