  • The Gashadokuro is a homage to Rito Revolto from Mighty Morphin Power Rangers.
  • The Skeleton Dance is referenced in this episode when Shaggy and Scooby distracted the Gashadokuro.
  • In Japanese mythology the Gashadokuro is said to be fifteen times the size of a regular human being. But in this episode the Gashadokuro can grow to giant size and shrink to human size at will.
  • Shimagura dresses up as a veiled harem girl, Mishi as a surgical-masked hospital nurse, Moshu as Megaman, Scooby the superhero, Scrappy the pirate, Shaggy the Native American, and Nigamora as a cat. Also, Ashiyama, Siba, and Koba dress up as vampires.
  • Fans consider this the first appearance of Scooby's superhero alter-ego Lightning Dog, but this is considered wrong as the costume Scooby wears is actually an early design for Lightning Dog.
  • The voice Clancy Brown used for Gashadokuro is the same one he used for Dogpound from Teenage Mutant Ninja Turtles.
