Right. Misterjaw had a thick German accent, and a sidekick named "Catfish", who (shockingly) was a catfish wearing a bowler and had a Brooklyn accent.
Jabberjaw on the other hand, was a Hanna-Barbera cookie-cutter doofus (See also; Grape Ape, Captain Caveman), and was a drummer in a rock band with three humans.
Misterjaw is often lost to obscurity, like most of the Pink Panther franchise...
