[3] 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.

McNamara (John Anthony Bailey) and Susan Talbot (Carol Anne Seflinger-[IMDB]).

Schlepcar transformed into the shiny metal-flake red Wonderbug (vocal effects provided by Frank Welker) whenever a magic horn (which played the bugle call for "cavalry charge") 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.

Wonderbug shared the one-hour time slot with other Krofft Supershow titles, including Magic Mongo, Bigfoot and Wildboy, Dr. Shrinker, The Lost Saucer, and Electra Woman and Dyna Girl.
