Watch Teenage Mutant Ninja Turtles 1987 online: Episode 4 The Mean Machines

After the batteries died in the alien crystal converger, Donatello, using spared circuits from the space ship, builds a tracking device to help locate the second fragment of the Eye of Zarnov. On the streets, the tracking device picks up the signal and leads the Turtles to a branch of a bank where a hold-up has just occurred. The Turtles thwart the would-be bank robbers, while Shredder and Baxter Stockman, who had followed the Turtles, locate the second fragment and return to Shredder's secret hideout. Shredder immediately contacts Krang and tells him of his recent acquisition and of his belief that if he were to hook up the second fragment to a computer, it will give them unlimited power. Krang is doubtful of Shredder's ability to succeed.
