I only saw this character in a couple of episodes and never learned his name. He was based on the stereotypical Cajun hillbilly, spoke with an equally stereotypical bayou accent and kept an alligator as a pet/sidekick.
Could this be Jambalaya Jake?
Jambalaya Jake lived in the bayou along with his pet alligator Gumbo (who seems to be much smarter than him), but the two decide to move to the big city after hearing it was easy pickings. The two make their hideout in the sewers of St. Canard, where they plot their crimes. Jake and Gumbo first appear in the episode "Can't Bayou Love." By using Launchpad McQuack as bait, they try and catch Darkwing Duck. But Darkwing shows them first hand that in the city it is not so "easy pickings."
