* SugarWiki/AwesomeMusic: The score, by Music/VinceGuaraldi and John Scott Trotter, is full of memorable cues. Also, the reprise of "Linus and Lucy" from ''WesternAnimation/ACharlieBrownChristmas'' is even better with that little flute bit added.
* EveryoneIsJesusInPurgatory: [[http://www.reverseshot.com/archive/entry/206/its_the_great_pumpkin_charlie_brown You bet.]] Although the notion of the Great Pumpkin as a religious metaphor was apparently {{Jossed}} by Schulz himself.
* FridgeHorror: The Great Pumpkin didn't appear because that was the huge pumpkin Lucy and Linus selected to be their Jack-o-lantern!
* JustHereForGodzilla[=/=]MemeticMutation: "I got a rock."
* NarmCharm: Some of the children providing the voices were too young to understand their lines, resulting in the classic awkward delivery that later became a staple of all ''{{Peanuts}}'' specials (the lines you hear are often a composite patched together from several different takes).
* NightmareFuel:
** The whole "Snoopy shot down behind enemy lines" sequence. That eerie flute music (coupled with the distant gunfire and air-raid siren) doesn't help.
** Not to mention the opening title sequence, especially the OminousOwl at the very end.
** Completely justified, of course, since this ''is'' a HalloweenSpecial we're talking about.
* TheWoobie: Linus, when he is still freezing in the pumpkin patch at 4 a.m.
** And, as always, Charlie Brown. Apparently this child is even deeply hated by adults, so much so that they would all give him a rock as opposed to candy.
*** [[{{Fridge Logic}} They may just hate Charlie Brown's costume. It's a mess.]]
** Schroeder plays some WWI songs for Snoopy. Snoopy dances to the music, but when Schroeder plays a couple of sad songs, poor Snoopy starts crying so hard that he leaves the party. It just makes you want to give Snoopy a hug.
