- The Cast Showoff: As with the Hex Girls' voice actresses in Witch's Ghost, Scott Ines gets to sing as Shaggy for a song.
- In Memoriam: The credits feature a dedication to Mary Kay Bergman, where this was her final performance as Daphne. She passed away just weeks after recording, and the film was released posthumously.
- What Could Have Been: Just imagine if Casey Kasem had either re-assumed his role as Shaggy in this film, or if he never had the falling out before Zombie Island began recording. He'd be the one singing "How Groovy." We know he can sing as Shaggy thanks to this little gem, so it's kind of disappointing he didn't sing here.
