The Stretcher

S1 E6: An arch-villain, The Stretcher, is manufacturing "Rubber Glubbers," evil robots who are stealing tires (right off police cars!), fire hoses, firemen's boots and anything else rubber in order to gather all the rubber in the world. The Mighty Heroes come into play, but they get all stuck up in rubber glue. They're put into a giant rubber ball and rolled off a skyscraper.
