Frank Welker does the voices of Fred and Scooby. Matthew Lillard does Shaggy's voice, Grey DeLisle does Daphne's voice, and Mindy Cohn does Velma's voice. In every episode the gang goes abroad and finds a super, funny and scary mystery to solve. Maybe encountering a ghost, or a robbery. Then they find the clues and the suspects and try and figure out who the villain is. In each episode there is a chase scene when the ghost chases the gang, usually Scooby and Shaggy. Soon, Fred decides to set a trap and Scooby and Shaggy are live bait. Then the ghost gets trapped and is unmasked. The villain is taken to prison, and sometimes even returns to have revenge on the gang. After a hard mystery, Scooby usually cheers "Scooby-Dooby-Doo!".
