How to Dress Like Scooby Doo Characters. The Scooby Doo gang (also known as "Mystery Inc.") are among the most recognizable cartoon characters of all time. One of the best ways to draw attention at the next costume party will be to get three of your friends to show up with you dressed as Fred, Shaggy, Daphne and Velma.
The final addition to your costumed group would be a plush Scooby Doo doll. Shaggy would be the best person to carry it, since Scooby has always unofficially been his dog.
