Plot hole: There is a "scarab alarm" when the blue scarab arrives, Shaggy even comments on hearing this. The problem is, The Blue Scarab is a comic book, so the villain and Shaggy wouldn't know what the Scarab alarm sounded like.

6.3/10. Maybe not the best Scooby Doo cartoon but way better than Shaggy and Scooby Doo Get A Clue. A few decent episodes in this one.
