Remember the Teenage Mutant Ninja Turtles (TMNT)? Yes, that cartoon sparked off at least one movie on the silver screen, a whole slew of toys as well as comics, it has yet to die off assuming this $4.99 Teenage Mutant Ninja Turtles Keychains was something new – and not dusted off some warehouse after years of being forgotten. These heroes in a half shell will feature their own sewer platform, complete with crazy fighting action for instant gratification? All you need to do was to toggle the control switch, and they will go into a fighting frenzy sans batteries. To get the whole bunch, you will have to fork out $20.
