While reading his favorite comic book, Daffy accidentally knocks himself unconscious and dreams he’s Duck Twacy, famous detective, trying to solve the case of the missing piggy banks. Taking a streetcar (conducted by Porky Pig, in a non-speaking cameo role) to the gangsters’ hideout, he meets up with such grotesque criminals as Pickle Puss, Eighty-Eight Teeth and Neon Noodle.
