Plot: Wonderbug's alter ego "Schlepcar" (so named due to its personalized California license plate "SCHLEP") was an old, beat up, conglomeration of several junked cars that looked like a rusty dune buggy. Like Herbie of Disney movie fame, Schlepcar was alive and could drive itself, and could also talk in a mumbling voice. It was found in a junk yard by teenagers Barry Buntrock (David Levy), C.C. McNamara (John-Anthony Bailey) and Susan Talbot (Carol Anne Seflinger). Schlepcar transformed into the shiny metal-flake orange Wonderbug when a magic horn was sounded. In his Wonderbug identity, Schlepcar had the power of flight and was able to help the three teens capture crooks and prevent wrongdoing.
