  • This episode contains one of the few references to Scrappy-Doo and Flim-Flam in the Scooby-Doo franchise since the 1980's. Flim-Flam's appearance is his first since The 13 Ghosts of Scooby-Doo, while Scrappy makes his first and only appearance since the 2002 live-action film.
    • Their portrayal as villains references the negative views that fans have of their time as main characters in the 1980's. They are commonly blamed for Scooby-Doo's decline during that decade and their unpopularity has been referenced everywhere from Cartoon Network (which reflected their unpopularity in their bumpers) to the villainous portrayal of Scrappy in 2002's Scooby-Doo.
    • Fred's statement that he does not know Flim-Flam is a reference to his standard continuity counterpart's absence from The 13 Ghosts of Scooby-Doo. Given that Velma was also absent from that series, her SDMI counterpart would likely not know him, either. 
  • Velma runs a blog about the gang. She finds out that Amy and her mother both follow it.
  • Though Velma regularly locks her door, Angie has a key and regularly invades her privacy.
  • This is the second time the gang meet Ed Machine face-to-face, after Where Walks Aphrodite.
  • There are six Skipper Sheltons: the clammer who owns the Clam Cabin, a sardiner, a shrimper, a manta-rayer, a kelper, and a sea-dragoner (whom they don't talk about). This parallels Daphne and her sisters, suggesting she has five (with the odd one being the astronaut sister).
  • Ernesto's group is missing the balding, gray-haired middle-aged guy from The Shrieking Madness.
  • In this episode, skeptical Velma believed a person in a costume to be a real supernatural creature. Amy appealed to her loneliness and her desire to have a secret friend.
  • This is the first time that Angel Dynamite has been hinted to be Cassidy Williams; Velma outright declares it.
  • Ernesto's statement, "We have to destroy the environment in order to save it" is an echo of the famous Vietnam-era quote, "We had to destroy the village in order to save it."

Animation mistakes and/or technical glitches

  • The statue represents Flim-Flam with his hands in his sweater pockets, but from behind, his hands are on his waist.

Inconstitencies/continuity errors and/or goofs/oddities

  • Despite having already met Ed face-to-face once before, the gang show no apparent recognition of him as the associate of Mr. E who spoke to them after the Aphrodite case. The only reasonable explanation is they met him at night and would not have been able to have a good look at him or it's just something they cared not to reference.
  • The gang doesn't seem to recognize the scuba gear as a potential clue.

Daphne: Oh look. Flim-Flam. Remember him Freddy?
Fred: You forget. I was away that year. I spent the summer tied up at trapping camp.Get it? Tied up... trapping camp.
Daphne: (Sighs) So tragic. 25 to life is a long stretch. Even for a preteen con artist. (Spots Scrappy-Doo statue) Wow, I haven't seen...
Fred: Look away Daphne. We all promised each other that we would never speak of him. Not ever!

Velma: Scooby? Velma. Put Shaggy on. (Pause for reply) Because you're almost impossible to understand on a phone.

Amy: ♪ My song fills your heart. From the depths of the sea. Please listen and learn. All you can learn from me. ♪

Skipper Shelton: Besides meself there are five Skipper Sheltons, all siblings of mine: a sardiner, a shrimper, a manta rayer, a kelper, and a sea-dragoner.

Velma: Hold on. Are you telling us that you were going to cause a major environmental disaster in order to get the cash to protest against major environmental disasters?
Ernesto: Yes. You must be willing to kill the environment to save it!
Mystery Inc: (In unison) Er no. I don't think that's right.
