The Creeping Creatures

S1 E2: A long time ago there was a town called Gatorburg, where alligators swam wild and free - and people got rich. Now, it's a ghost town. The reptiles have all disappeared. But when Scooby and the gang receive an imitation Gatorburg purse, they decide to see for themselves if the beasts really are gone. Forced to spend the night when someone steals the engine to the Mystery Machine, they soon discover that the gators have indeed returned ... only these swamp creatures have comb-overs, walk on two legs - and don't like visitors!
