Ep 63. A Fly In The Ointment

When Zipper, who has been feeling left out of the action tries to single-handedly battle Nimnul, he gets sucked into the Nimnul's latest invention, the "modumizer," which causes him and Nimnul to exchange heads! Soon after, Zipper is caught by soldiers who think he is a space creature, forcing Nimnul-the-fly to join forces with the Rangers to get Zipper back. In the course of the rescue the modumizer switches all the Rangers' heads, adding confusion to chaos. Through solid team work, however, Zipper is rescued, the Rangers and Nimnul are brought back to normal, and Zipper cleverly defeats Nimnul single-handedly, just as he set out to do.
