Legendary South African cartoonist Dov Fedler drew the Jet Jungle comic strips which appeared in Family Radio & TV Magazine (English), and in Patrys (Afrikaans), in the 1970s.
Jet Jungle promoted Jungle Oats and Black Cat Peanut Butter. He also featured in a Radio Programme (Jet Jungle voiced by Brian O'Shaughnessy), and a Mego Figure was produced.
