As @Brainspore mentioned, the Saturday morning cartoon was spun off from the animation in the film’s credits. But the cartoon show also had The Ant and The Aardvark, and an Inspector Clouseau cartoon (whose theme music, IIRC, was from A Shot in the Dark). (Also Misterjaw and Tijuana/Texas Toads, along with several other cartoons that I didn’t otherwise remember.) The Pink Panther was continuously antagonizing another character (a painter?) who, for some reason, I confused with Inspector Clouseau.
But this was the first I’d heard of the Panthermobile or the breakfast cereal.
