History NightmareFuel / HalloweenIIISeasonOfTheWitch

* The sequence of all those kids throughout America on Halloween, buying and wearing Silver Shamrock masks as company vans drive through neighborhoods reminding them about "the big giveaway." Including Dan's own kids. All while the commercial jingle plays in the background. You just know most, if not ''all'', of those kids are going to die that night. It's probably one of the most chilling sequences in the entire movie.

* The death of Grimbridge at the hospital. The robot thug pinches his nose bridge hard enough to crush it, then ''pulls it outward'', causing his entire face to become convex, bulging outward at a weird angle.

* The fact that at the end, ''Conal probably won'' when you consider the FridgeLogic. The commercial was set to air around the U.S., and we have different time zones, meaning at least one timezone will have all its kids killed.

* The practice run on the Magic Pumpkin commercial. [[spoiler:The spell in the seal triggers and messily rots away Buddy's kid's head as he holds it in ''silent'' agony. As the kid falls dead, a huge swarm of snakes and insects is released from what was his mouth, which eventually kill Buddy and his wife.]]

* Conal Cochran himself manages to be more horrifying than his own robots. The amused way he talks about [[spoiler:murdering millions upon millions of children]] as the best kind of joke on them.

** His lecture on Halloween and what he feels it ''actually'' is is equally chilling. It makes you think that - beyond it being a great joke on the children, he's taking out his bitterness over what Halloween has become.

** She's also ''still alive'' and struggling to breathe as - foreshadowing the later test run - a spider emerges from her mouth.

** She's also ''still alive'' and struggling to breathe as - foreshadowing the later test run - bugs begin to emerge from her mouth.

* Silver Shamrock's robotic employees. Throughout the film, they gruesomely murder whoever threatens to expose Conal Cochran to the world...or simply hates the company.

* The "misfire." Marge discovers the chip hidden inside a Silver Shamrock trademark on one of the masks and removes it, prompting a laser beam to fire out out and strike her in the face, tearing her lips off and exposing her teeth.

* The practice run on the Magic Pumpkin commercial. Even the {{Narm}} couldn't sugar-coat what happened: [[spoiler:The spell in the seal triggers and messily rots away Buddy's kid's head as he holds it in ''silent'' agony.

* Just the idea of a commercial looping over and over until you die is just bone-chillingly frightening. Added to the fact that this is one of the few films ever made that actually (and graphically) killed children.
