Scooby-Doo! Mystery Incorporated
In addition to the traditional cases they always solve, the team finds itself being nudged into the uncovering of a dark secret that is hidden in the past of Crystal Cove. Following cryptic hints from a faceless mystery-man known only as "Mr. E." (a play on "mystery"), the gang unearths the legend of a cursed Conquistador treasure, the secret history of Crystal Cove's founding Darrow Family, and the mysterious, unsolved disappearance of four mystery-solving youths and their pet bird—the  Mystery Incorporated. Standing in the way of solving this mystery, however, there are the romantic entanglements pulling the kids apart: Shaggy finds himself unable to put his new romance with Velma ahead of his longtime friendship with Scooby, while Daphne pines for a trap-obsessed Fred, who obliviously struggles to realize that he shares her feelings, too.
