* "Surprise Party": A group of college girls go to a Halloween party, where the [[FinalGirl sweet and virginal one]] (Creator/AnnaPaquin), dressed as Literature/LittleRedRidingHood, is hoping to finally meet the man of her dreams...

** There's a trick 'r treater dressed as Michael Myers from the ''Franchise/{{Halloween}}'' movies. Also, the character set up as an obvious FinalGirl, as noted above, is named Laurie.
** Also, a colourized version of the original ''Film/HouseOnHauntedHill1959'' is playing on TV in one scene, along with ''Westernanimation/ScoobyDoo on Zombie Island''.
** Naming a SerialKiller "Steven" may also be an Music/AliceCooper reference.
** Mr. Kreeg says "You gotta be fuckin' kidding," while [[spoiler: Sam's severed hand skitters across the floor]], much the same way as Palmer said the exact line in ''Film/TheThing1982'' while [[spoiler: Norris' head ran around the lab on spider legs]]. The same director would homage the scene from ''The Thing'' again in ''Film/GodzillaKingOfTheMonsters2019''.

* PsychosexualHorror: A group of flirtatious girls are shopping for Halloween costumes and picking up dates for a party that night. They have in tow Laurie, who is described by her eldest sister as "the runt of the litter". Laurie doesn't want her sister to help her hook up with someone because she wants her "first" to be "special". She is followed to the party in the woods by [[spoiler: a man dressed as a vampire who had already killed a woman in an alley. He attacks Laurie, and there is a horrific noise that gets the attention of the girls at the party, only for a figure wrapped in Laurie's red cloak to fall from the trees. It's revealed to be Steven Wilkins, the school principal and already having been shown as a murderer a few times over. He begs for help, as Laurie steps out of the woods, snarking that the other girls told her to play hard to get and Wilkins had bitten her for it. It is then quickly revealed that Laurie, her sister, and their friends are all werewolves as they begin to strip down, first their clothes and then their flesh, and the men they'd enticed to join their party were their victims for the night.]] RewatchBonus comes into play as one realizes their earlier conversation at the costume shop was full of hidden clues about what was going on; see {{Foreshadowing}}, above.

* BusFullOfInnocents: In "Halloween School Bus Massacre", a group of trick-or-treaters travels to a local flooded quarry where Macy recalls the urban legend of the "Halloween School Bus Massacre," which claimed the lives of eight children with disabilities in a school bus on Halloween. The driver, who had been paid by their worn-out parents to dispose of them, drove them to that place to kill them. One of them broke free and attempted to escape. But instead wound up sending the bus over the quarry edge with the children shackled inside. The children all perished and the driver was never heard from again.

* BlueAndOrangeMorality: Sam enforces the rules of Halloween, [[DidWeJustHaveTeaWithCthulhu passively observing those who obey them]] and [[TheScourgeOfGod targeting those who don't]]. [[spoiler:Kreeg is spared for accidentally complying to the same rule he broke.]]
