Inspector Willoughby is a cartoon character created by Walter Lantz, and named after the Hollywood avenue which runs alongside the building where Lantz's office was housed (at 861 Seward Street). In Mississippi Slow Boat (1961) the character is addressed as Inspector Seward Willoughby. His cartoons were often shown on The Woody Woodpecker Show alongside Woody Woodpecker, Chilly Willy and Andy Panda.
