This is the first Scooby-Doo animated series since 1991 to make extensive use of the Castle Thunder sound effect, which Hanna-Barbera began to stop using around 1994, and was very rarely used on What's New, Scooby-Doo? and on none of the post-2003 direct-to-video Scooby-Doo movies, to be replaced with new digitally-recorded thunderclaps.
In episode 8, there is one scene where actual footage from a few of the Scooby-Doo direct-to-video movies is used. Shaggy even converses about the events in that movie.
