Although many fans pegged "Space Station Scooby" being listed 14th on the Scooby-Doo and Guess Who? season 1 set as wrong, given it was the season finale, the copyright date for the episode lists 2018 whereas all others after it list 2019, so the placement on the set may actually reflect the order in which it was produced in. In addition, given "The High School Wolfman's Musical Lament!" features a clip show of scenes from the series, that episode may have been intended as the true season finale.
James, who inspired this week's fun fact again, also pointed out that there is an astronaut suit in "Dance Matron of Mayhem!" that looks exactly like the gang's in "Space Station Scooby." It's probably more likely that the "Dance Matron of Mayhem!" astronaut suit was designed to look like the gang's, not the other way around, which would serve as further evidence for "Space Station Scooby" airing 14th rather than 26th.
