Shaggy, Scooby, and Scrappy are race car champions in America, but winning a race seems to be the least of their troubles, because, across the map in spooky Transylvania, the Wolf Man has decided to retire, leaving Dracula and the other monsters one driver short for their race.
Scooby-Doo and the Ghoul School is, as always, an enjoyable adventure that feels very strange compared to the rest of the animated films released after the '80s. This is simply because of the absence of the rest of the Mystery Inc. gang, Velma, Daphne, and Fred, as well as the lack of Mystery Machine rolling about. It is also, yet again, another Scooby-Doo animated film that doesn't feature the classic unmasking of any monsters, but instead plays on the idea that all of these monsters are very real.
