Notes/Trivia

 * Flim-Flam has an exhibit in the Crystal Cove Spook Museum. He is incarcerated, serving 25 years to life.
 * Scrappy-Doo is also there, but they have sworn never to speak of him.
 * Velma runs a blog about the gang.
 * They meet Ed Machine again face-to-face, with absolutely no recognition of him as the associate of Mr. E who spoke to them after the Aphrodite case.
 * There are six Skipper Sheltons (the clammer who has appeared before, 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).
 * 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.
 * 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."
