[[AC:"Reflections in a Ghoulish Eye"]]
* The title is a spoof of the title of a novel, ''Reflections in a Golden Eye''.
* During the scene where Flim-Flam and Scrappy pretend to be detectives arresting the gang, Scrappy introduces himself as "Elliot Messy," a nod to [[Series/TheUntouchables Elliot Ness]], though the character was a Treasury agent, not a detective.

* Scooby and Ghoulio sing "To all the Ghouls I’ve Loved Before," which is a parody of "To All the Girls I’ve Loved Before" by Julio Inglesias and Music/WillieNelson.
* Replace "B" with "P" and "bad luck" with "pool" in Flim-Flam’s "'Trouble with a capital 'T' and that rhymes with 'B' and that stands for 'bad luck'" line and you have a quote from ''Theatre/TheMusicMan''.

** The fictional movie's title is displayed in the same font style used for the titles in ''Film/KingKong1933'' and ''Film/TheSonOfKong''.

** As Dr. Frankenscoob, Scooby shouts, "[[Film/{{Frankenstein 1931}} IT’S ALIVE! IT’S ALIVE!]]"
