 A 1930s football player named the Rambling Ghost placed a curse on his football team. Now it seems he really is a ghost who is back from the grave to send his ex-team s star quarterback into oblivion. It s up to Scooby and the gang to solve this mystery. . . . Blue Falcon and his inept mechanical sidekick, Dynomutt the Dog Wonder, face their deadliest threat yet. Six of their arch-foes - The Gimmick, Lowbrow, Queen Hornet, The Worm, Fishface and Superthug - have formed the Injustice League of America. Their main goal: wipe out Blue Falcon and Dynomutt. The super-heroic duo s only chance is to use a bit of psychology to undermine this terrible team.
