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 each episode, Scooby and the gang go somewhere and encounter a mystery. The mysteries always have a monster or a ghost as the villain; next the gang splits up and finds clues. At the end, Fred sets a trap. After the monster is caught it turns out to be a person in a costume. The villains always have a motive; some might be smugglers, some might be revenge-seekers, they could be anything.
The gang's airplane lands on an island, but it's the wrong place thanks to Shaggy's bad airplane flying skills. They soon discover the entire island is one big graveyard haunted by a ghost! Will this be the gang's last mystery?
The gang is taking a walk when they enter Scooby in a tournament where dogs fight by mistake. And when the day of the tournament comes, Scooby is nervous. He has to fight some pretty brutal dogs. But the ghost of Champion Dog comes and Scooby must fight the fight of a lifetime!
