"Reflections in a Ghoulish 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 Elliot Ness, though the character was a Treasury agent, not a detective.
- Before leaving the room, Flim-Flam does a disclaimer:
- When Daphne, Shaggy and Scooby are sucked into the demon mirror, they are shown in a room with several staircases going in multiple directions including upside down, it alludes to M. C. Escher’s well-known piece of art titled "Relativity."
- Episode title is based on The Greatest Show on Earth. The episode title also alludes to the well-known phrase "The Greatest Show on Earth", which was the slogan of the Ringling Bros. and Barnum & Bailey Circus that started in 1870.
- Professor Phantasm bears more than a few similarities to sinister master G. W. Dark of the Cooger and Dark Circus.
- While Zagraz looks like Merlin, his name could be a reference to the wizard from He-Man and the Masters of the Universe (1983).
- When Daphne, Shaggy, Scooby and Scrappy are singing, they make a reference to catchphrase "where’s the beef?" popularized by Clara Peller in a 1984 commercial for Wendy’s fast food restaurants:
If you’re in a hurry
And want a great big feast
Drag on down to Dragon’s
And just say "Where’s the beast?"
- While cooking soup, Scooby sings the The New Scooby-Doo Movies theme song.

- Episode title is based on the song "Spooky Little Girl Like You" by The Zombies.
- Scooby singing "Hawaii lies over the ocean, Hawaii lies over the sea," is a takeoff of traditional Scottish folk song "My Bonnie Lies Over the Ocean."
- Daphne refers to pilot Charles Lindbergh, famous for making the first non-stop trip across the Atlantic Ocean, by saying, "Look again, Lindbergh, that’s not sand, it’s snow!"
- 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 Willie Nelson.
- 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 The Music Man.
- The mock game-show "Let’s Make ’Em Squeal" parodies Let's Make a Deal with Weerd assuming the name "Haunty Maul", spoofing Monty Hall, the host of the aforementioned game show.
- Episode title and plot is based on It's a Wonderful Life.
- At one point, the President of the United States himself urges Scooby to rethink his retirement rand ejoin the team. Not only is the president designed after Ronald Reagan, but on his desk is a jar of jellybeans. Reagan was famous for loving Jelly Belly brand Jellybeans.
- "Kwackyland" is based on the whimsical world of living objects, Wackyland, consisting largely of surreal, Dali-like imagery and free-floating objects that obeyed no laws of standard physics in Porky Pig episodes "Porky in Wacky Land" and "Dough for the Do-Do", as well as being a major part in Tiny Toon Adventures, where Gogo Dodo is from there.

- After the gang, plus Vincent Van Ghoul, are sucked into fictional movie ‘The Son of the Bride of the Ghost of Frankenstein,’ the movie cuts to a logo of Scooby imitating the MGM lion logo and the words "Ranna Rarrera Extravaganza."
- Other than Vincent Van Ghoul and Flim-Flam, in "That’s Monstertainment" Shaggy, Scooby, Daphne and Scrappy are given recurring roles in the Frankenstein movie mythos: Scooby Doo as mad scientist Dr. Frankenstein, or in this case, Dr. Frankenscoob; Scrappy is "Egad", which is a parody of "Igor"; the misshapen servant and lab assistant to Dr. Frankenstein; Daphne is both Dr. Frankenstein’s fiancée, Elizabeth, with her dialogue’s indication and the Bride of Frankenstein with her hair and appearance; and Shaggy’s role of Constable Von Shaggobon is a reference to the recurring role of the concerned lawman who goes to investigate what the doctor is up to when the townspeople start to get worried about his unnatural work.
- As Dr. Frankenscoob, Scooby shouts, "IT’S ALIVE! IT’S ALIVE!"
- The fictional movie is a combination of the black-and-white film starring Boris Karloff and its sequels/parodies, Frankenstein (1931), Bride of Frankenstein (1935), Son of Frankenstein (1939), and The Ghost of Frankenstein (1942).
