Notes/trivia

 * The idea of a crossover had been around for about ten years, but it wasn't until co-writer Jeremy Adams's suggestion that it went forward. Getting an early season pick-up meant the animation could be done early. Episodes of Scooby-Doo, Where Are You! had appeared in previous episodes to the crossover.
 * Since this is a Supernatural episode, the events in the animated world of Scooby-Doo are not kid-friendly.
 * Before its TV debut, the episode had an early screening on March 20, 2018 during PaleyFest 2018.
 * This is the first time new Scooby-Doo material on the CW since the final episode of Shaggy & Scooby-Doo Get a Clue!
 * During the scene where Mystery Inc. and the Supernatural gang run between the doors, Scrappy-Doo is briefly visible.
 * The episode features a montage scene with the Scooby-Doo, Where Are You! theme song, mainly the scene where both groups flee the ghost and try to board it up behind doors with no luck.
 * During the episode, Fred and Shaggy both suffer actual injuries, a bloody nose in Fred's case and a broken arm in Shaggy's. This is due to the unique circumstances of the episode since, as Shaggy points out, he never gets hurt no matter what dangerous stunt he pulls. Before returning to the Supernatural world, Castiel uses his powers as an angel to heal Shaggy's injuries, making Shaggy think that he was wrong about breaking his arm.
 * During the explanation scenes, both in the cartoon world and the real world, the episode features intercut moments similar to what is shown when Mystery Inc. solves a mystery and uncovers the bad guy's identity and how they did it.

Animation mistakes and/or technical glitches

 * None known.

Inconsistencies/continuity errors and/or goofs/oddities

 * From an in-universe perspective, Scrappy's cameo makes little sense at this point (although Scrappy's Birthday would later retcon Scooby and Shaggy to have known him since birth).
