Courageous Cat and Minute Mouse
In the animated series, the pair are anthropomorphic animal superheroes without known secret identities (the green-eyed caped crimefighter and his squeaky-voiced companion are usually addressed as simply "Courageous" and "Minute") who live in the Cat Cave and, when summoned via the Cat Signal over their television set, race to the scene of the crime in their sleekly feline red Cat Mobile which can convert into both the extendable-winged Cat Plane and submersible Cat Boat and thwart the criminal plots of various villains who threaten Empire City.
Though they fought many miscreants, the duo's recurring arch-enemy, who appeared in nearly every episode, was known as Chauncey "Flat-Face" Frog.
The five-minute length of the cartoons made the series suitable for use as interstitials or airtime fillers, especially to accommodate a movie or show that ended at an unusually early time, as well as animated content for local children's shows.
