There is no Mystery Inc or Mystery Machine in this movie. It's just Shaggy (wearing a red shirt instead of a green one) and Scooby (and unfortunately, Scrappy, tho he doesn't feature prominently) and Shag's girlfriend Googy. Shaggy lives in an alarmingly large, mansion-esque house and is chosen by Count Dracula to become a werewolf so he can take part in a race for monsters.
Despite looking cute and cuddly as a Werewolf, Shaggy obviously doesn't want to do it but Dracula promises to change him back to human if he wins. What follows is a Scooby Doo version of the Wacky Races as insane customized cars battle it out on an anything-goes Transylvanian race-course.
The majority of laughs come from Dracula, ever so desperate to keep his wicked plan from falling apart and always making a complete idiot of himself.
It's also new to see Shaggy not jump into Scooby's arms every time he sees a monster. And this time they're real too , not just some guy in a mask.
I would definitely recommend this to Scooby fans and those who are just total Scooby completists (like me). It's very funny and totally rewatchable.
The DVD is in 1.33:1, as drawn and comes with a Dolby Mono soundtrack.
