- In the book, Sparkles is never called out by name as the characters simply refer to him as ''Dragon''.
- Sparkles is one of the few villains in the Goosebumps franchise to not have much of a presence in their respective books besides the end.
- His name was actually introduced in HorrorTown, despite not having a name before, only being referred to as "Dragon". Though it's been debated whether or not "Sparkles" is his real name or not.
- He could also be based off the "Red Dragon" from the fantasy tabletop (RPG), Dungeons & Dragons and eventually it's animated TV series counterpart of the same name where it appeared in the season 2 episode Day of the Dungeon Master.
- His design was also heavily inspired by Charlock The Red Dragon (originally referred to as Sharlock) from the 2005 live action role-playing adventure game MagiQuest.
- Another reference can be found as he was also inspired by Smaug, the main antagonist of the 1937 J. R. R. Toliekin's novel The Hobbit as well as the Peter Jackson's film adaptations of The Hobbit where he was voiced by Benedict Cumberbatch.
