Common Sense Note
Parents need to know that this movie has more intense, scary special effects than you'll find in the cartoon Scooby-Doo features. The characters are in frequent peril, though no one gets hurt. There is some drug humor (as "Pass the Dutchie" plays on the soundtrack, what appears to be marijuana smoke turns out to be something else) and some vulgar jokes and graphic bathroom humor. The girls wear very skimpy clothes.
Fred is transferred into Daphne's body and says, "Hey! Now I can look at myself in the mirror!" Fred and Daphne kiss. Plenty of short skirts and tight tops that don't leave much to the imagination. Fred fashions himself as a womanizer and includes Pamela Anderson as one of his admirers -- though he does admit to Velma that "I'm a man of substance; dork chicks like you turn me on, too."
Lots of toothsome, scary faces, zombies, evil men in charge of teens on an island. Lizard monsters and zombies chasing the gang, even inhabiting the bodies of Velma, Fred, and Daphne.
Besides "zoinks" and "jinkies," there are little slips, like "beeatch," booty, "your mom eats cat poop," and for the French speakers out there: "Voulez-vous couchez avec moi, c'est soir."
Friendship and teamwork are less important here than in other Scooby-Doo features, as the gang tries to salvage their team dynamic; but their efforts are overshadowed by strange zombies and a madman's attempt at mind control. The action takes place on an island alongside partying college kids. These peers are more serious partiers than seen in any previous Scooby-Doo features -- and Velma getting drunk raises a big flag.
The consumption of food is the devoted past time of Shaggy and Scooby. Daphne is materialistic, carrying seven matching bags onto the plane. Telemundo is mentioned, so is NASA.

It is obvious that Shaggy is into pot, by the way the song "Pass the Dutchie on the Left Hand Side" plays while smoke rises from his van. But wait, they are just grilling some eggplant burgers in there. Sure. And Shaggy's love interest is named Mary Jane. "Mary Jane is my favorite name," he says dreamily. Velma gets drunk at a bar on a tiki drink.
