-> '''Wren''': Halloween isn't about making friends. It's about TERROR!\\
'''Reynold''': And CANDY!\\
'''Wren''': It's about showing the world what you truly are.

It's [[AllHallowsEve Halloween night]] in suburbia, and twin siblings Wren and Reynold are going trick-or-treating. Mom puts one sibling in charge (while the other gets stuck with the lame candy corn costume), and they saunter forth in pursuit of sweets.

But one house doesn't go exactly as planned. Where the kids expect a dorky grown-up with candy for the taking, a hideous monster pops out the door and abducts one of them! It seems that a horde of Grubbins have invaded Auburn Pines under the orders of a HotWitch named Dorsilla. Out to steal every lollipop, jellybean and jujube in town, they mistook your brother or sister for a huge chunk of candy corn. It's up to you to save your other half. [[SiblingRivalry Not out of love]] - but out of fear of getting grounded!

''Costume Quest'' is the first of four titles from Creator/DoubleFine for which Creator/TimSchafer took a backseat to the most trusted members of his team. This game is from the imagination of Tasha Harris, former Creator/{{Pixar}} animator and Lead Animator of the creatures in ''VideoGame/BrutalLegend''.

In this simple old-school RPG themed around Halloween, the player goes on quests to find their kidnapped ally and save Halloween...by trick-or-treating. You must visit each house in the area and knock. If it's an adult, he or she will reward you with candy. If it's a monster looting the house, a battle encounter begins.

During a battle, for no reason other than RuleOfCool, whatever costume you are wearing transforms you into a massive, {{Kaiju}}-sized version of what your costume was supposed to represent. You start off in a blue cardboard box that's supposed to be a robot, so what happens when you transform? You become a Anime/{{Voltron}}-esque, missile-blasting mech! Attacking and defending is performed with well timed ActionCommands, like those seen in VideoGame/SuperMarioRPG, VideoGame/PaperMario, VideoGame/ShadowHearts and VideoGame/PennyArcadeAdventures.

Outside of battle, players explore the neighborhood in search of new houses and costumes; there are eleven outfits in all, most of which are built from scratch. Each costume consists of three household materials, such as cloth or rope, and an instructional blueprint. Finding all the pieces yields your snazzy handmade digs, which unlock both combat skills and "Exploration Abilities" for reaching new areas.

Candy is the game's currency and can be used to purchase Battle Stamps. These helpful stick-on accessories can power up stats, enable StandardStatusEffects, or unlock unique single-use abilities in combat.

The game initially released in October of 2010 for XBLA and PSN. A DLC expansion, "Grubbins on Ice", which was a follow up with a Christmas theme, came out in December of 2010. In October 2011, a PC version was released through Steam and included both the original game and the DLC as one package. As of May 2013, the game has been ported to Mac and Linux as well.

A sequel was released in October 2014. In it, Wren and Reynold have to go through time to stop candy-hating DepravedDentist Dr. Orel White, who intends to destroy Halloween forever.

There is a also a graphic novel, ''Invasion of the Candy Snatchers'' by Zac Gorman.
!!The ''Costume Quest'' games provide examples of:

[[folder:Costume Quest]]
* ActionCommands: The combat is ripped straight out of ''VideoGame/SuperMarioRPG'', ''VideoGame/ShadowHearts'' and ''VideoGame/PennyArcadeAdventures''.
* AdultsAreUseless: Hilariously lampshaded every possible chance there is. At least one grown-up has seen the evil beasts himself - and thinks they're [[TeensAreMonsters just teenagers]].
* AndYouWereThere: The twins' parents have the same models as Drusilla and Dorian, with different clothes.
* AttentionDeficitOohShiny: Reynold, especially in "Grubbins on Ice". Ooh, look! A quarter!
* ArtShift: In the field, the game uses a very simple, cartoony art style. In battle, the combatants are depicted as slightly more realistic - the player characters becoming their costumes, and the monsters becoming more intimidating and ugly. It's the typical difference between American animation and certain art styles of American comic books.
* BackFromTheDead: The Unicorn's special.
* BecomingTheCostume: In battle characters become a giant superpowered version of their costume for no reason other than RuleOfCool and RuleOfFun.
* BigBad: Big Bones.
* BigfootSasquatchAndYeti: You can encounter Yetis and wear a Yeti costume in the DLC.
* BigEater: Again, Big Bones.
* BeefGate: [[spoiler: The return of [=BoJonn=] in the Arcade.]]
* BlushSticker
* BoringButPractical: The starting Robot costume is one of the few to provide a bonus to your attack power, has a really strong special attack that does high damage to every enemy and does further damage over time, and most importantly, allows you to [[ZipMode dash around on roller skates when exploring]]. You'll rarely have reason not to equip it on your lead character.
* BrokenBridge: Several, usually in the form of locked gates and [[NPCRoadblock stubborn guards]].
* BroughtDownToNormal: At several points the characters end up either getting their costumes destroyed or stolen, and as such, have to spend a few points rebuilding or building a new costume to get the previous ones back.
* CallingYourAttacks: Several, and several parodies.
-->'''Hero''': Now you'll taste my Missile Barrage!\\
'''Dorsilla''': What's that? I couldn't hear you over the sound of that sudden tornado. ''[snaps fingers]''\\
'''NPC in Dragon costume''': Fire Breath! Fire Breath! Why aren't you burning from my Fire Breath?
* ClassicalMovieVampire: Take a wild guess.
* CliffHanger: [[spoiler: Grubbins on Ice ends with the kids going through the portal to return home, only to end up in a [[PhantomZone void-like dimension]] containing even more portals.]]
* ClothesMakeTheSuperman: Core game mechanic. In an enemy encounter, Wren and Reynold transform into a building sized version of what their primitive, handmade costume is supposed to represent. Here's a list by category of use.
** Attack: [[HumongousMecha Robot]], [[GratuitousNinja Ninja]], [[AllHallowsEve Pumpkin]], [[ClassicalMovieVampire Vampire]], [[GhostPirate Pirate]] (DLC only), [[FacelessEye Eyeball]] (DLC only).
** Defense: [[KnightInShiningArmor Knight]], [[BigfootSasquatchAndYeti Yeti]] (DLC only).
** Support: Art/StatueOfLiberty, {{Unicorn}}.
** Special: [[SpaceCadet Spaceman]], [[GiantEnemyCrab French Fries]], [[PantheraAwesome Black Cat]].
* CrypticBackgroundReference: Repugia.
* DealWithTheDevil: [[spoiler: Dorsilla with Big Bones.]]
* DefeatMeansFriendship: [[spoiler: First the Grubbins, then the Trollbogs, then the Crestwailers.]]
* DeathIsASlapOnTheWrist: Losing a battle just means you have to try again.
* DoorToBefore: The Sarcophagi allow you to teleport back to previous areas.
* TheDragon: [[spoiler: Dorsilla]]
* DualBoss: The final fight of Grubbins on Ice pits you against [[spoiler: Big Bones and Araxia]].
* EarlyBirdCameo: [[VideoGame/{{Stacking}} Charlie Blackmore]] appears in a secret cave in Repugia. So does an advertisement for the game he'll be appearing in.
* EnemyCivilWar: You join one in ''Grubbins on Ice''
* EnemySummoner:
** [=BoJonn=] is one until you destroy his megaphone.
** Subverted with Big Bones. In battle, sometimes he'll summon a trio of tough-looking monsters... and then eat them to fuel a powerful breath attack on one of the heroes.
* EvilTwin: [[spoiler: Dorsilla]]
* {{Expy}}: The Black Cat Costume is a [[VideoGame/BrutalLegend Laser Panther]] without the purple streaks.
** The Pirate costume is [[VideoGame/MonkeyIsland LeChuck.]] sans beard.
** The Unicorn looks [[VideoGame/RobotUnicornAttack pretty badass]], with emphasis on both "pretty" and "badass."
* FailedASpotCheck: The monsters mistake the costumes for [[RuleOfFunny walking, talking candy or food]] several times. They are also easily fooled by the hero wearing a Grubbin costume despite everyone else in the group clearly not dressing as Grubbins and your main character clearly being a small child.
** At the start of ''Grubbins on Ice'', Reynold misses a huge glowing portal because he's distracted by a quarter that's just a few feet away from it.
* FelonyMisdemeanor: Oh no! The villains are monsters trying to steal all the Halloween Candy!
* {{Foil}} Wren and Reynold = Drusilla and Dorian.
* ForScience: Lucy, constantly.
* FreudianExcuse: Some Repugians in the DLC will roar "I had a rough childhood!" before assaulting you.
* GenericCuteness
* GettingCrapPastTheRadar: "I hope I'm the only banana costume. Last year? TOTAL bananafest!"
** A male NPC mentions that his husband said that there shouldn't be any kids and don't have much candy.
* GiantEnemyCrab: The French Fries turns you into this. Yes, really. A giant crab with french fry legs, french fry pincers, and a french fry container shell. And it's [[LethalJokeCharacter actually pretty effective]].
* GrimReaper: Big Bones, an enormously ''fat'' Grim Reaper.
* GRatedDrug: Candy. "Awww YEAH! That's the sugar daddy likes!"
* [[HalloweenEpisode Halloween Game]]
* {{Halloweentown}}: Repugia
* HandWave: Lampshaded. When the kids need to get down from the Ferris wheel, your character comes up with a brilliant plan. [[GilliganCut Immediate cut to]] the kids on the ground. Bonus lampshading with fourth wall damage when a character explicitly mentions suspending disbelief.
-->'''Everett''': I can't believe you thought of a way down that was so simple and practical.
* [[HawaiianShirtedTourist Hawaiian-Shirted Final Boss]]: Big Bones' robe has a tropical floral pattern on it, to further the theme of him being a FatBastard.
* AHellOfATime: One monster says Dorsilla is so bad that [[spoiler: they don't want her to return to Repugia.]]
* HealingHands: The Art/StatueOfLiberty's power is to do this through sheer [[PatrioticFervor Patriotism.]]
* {{Homage}}: Tasha Harris says the game is inspired from many things. The isometric diagonal view of the town is from Videogame/{{Earthbound}}, the monsters are inspired from Film/{{Labyrinth}}, the art is inspired from Creator/HayaoMiyazaki and [[VideoGame/TheLegendOfZeldaTheWindWaker Wind Waker,]] and the whole game is a love letter to Halloween and costumes (in particular, handmade ones.)
* HopelessBossFight: "Grubbins on Ice" starts you off fighting against three Level 14 Repugiarchs; at this point, it's impossible to be higher than Level 10. You actually can win the fight if you hit '''all''' the prompts and catch some luck with the enemy's choice of targets, but FailureIsTheOnlyOption and it dumps you into the next scene as if you lost. (You still receive a hefty experience bonus if you win, though.)
* HotWitch: Dorsilla, in universe, and she boasts it. [[spoiler:After her defeat, she wonders if her failure to conquer the world is because she's too pretty.]]
* HowUnscientific: Lucy does this a lot.
* HumongousMecha: The robot costume.
* IdiotHero: Reynold leans to this in the DLC.
* [[IGotARock I Got Old Marzipan]]
* InvisibleToNormals: The monsters seem to be somewhere between this and triggering a WeirdnessCensor. Most adults don't notice them at all, and those that do assume they're teenagers or natural phenomena.
* IronicEcho: [[spoiler: Dorsilla uses a recording of the main character to tear the sibling away from him/her. Dorian uses a recording of his sister to expose her plot to usurp Big Bones.]] "That's inadmissible!"
* {{Kaiju}}: The battles become these. The various silly goblins transform into massive, uglier monsters, and the children transform into giant, more lifelike versions of what their costumes are supposed to represent.
* KidsAreCruel: The gang of mummy children. But it turns out [[spoiler: the gang leader is the only one keeping their violent tendencies in check.]] This is played for laughs.
* KidsPreferBoxes: The first costume.
* LaResistance: You help out the monsters against their oppressive new government in Grubbins On Ice. They even dress like Che Guevara. Citizens wonder why, despite being members of the resistance movement, you lack beards and berets.
* LeanAndMean: Dorsilla reaches NoodlePeople levels during her boss battle.
** Also the Pumpkin and Vampire costume look pretty scrawny and wicked, but they are actually on the heroes' side.
* LeaningOnTheFourthWall: Everett does this the most. Or maybe he just really likes ''TabletopGame/DungeonsAndDragons''.
-->''Everett'': A mall? This looks more like a dungeon! Which I am totally prepared for! Hey look! A dungeon map!\\
''Everett'': He just took a natural 20 to the face and didn't take ANY damage!
* LifeDrain: The Vampire's special.
* LighterAndSofter: The difficulty is easier, and the humor is more low key than Double Fine's previous works.
* LimitBreak: Called the Combat Ability, it's measured by a circle-shaped energy meter that fills up in three turns.
* LovecraftCountry: A very cutesy version.
* LovecraftLite
* MacrossMissileMassacre: The Robot's special.
* MagicVersusScience: Lucy refuses to call the monsters as such, and adamantly believes they are aliens.
* ManipulativeEditing: [[spoiler: Dorsilla uses this to drive the siblings apart.]]
* MeaningfulName: My Little Panacea. Not only is it a PunnyName reference to ''WesternAnimation/MyLittlePony'', but ''Panacea'' means a cure-all or wonder drug. The Unicorn's special attack is a healing spell.
* TheMedic: The Art/StatueOfLiberty and Unicorn costumes. The Vampire can heal the party as well, despite being an attack-based class.
* MookMedic: In every species of Repugian monster. Grubbins, Trowbogs and Crestwailers each have their own healing class.
* MiddleManagementMook: Bojonn.
* {{Mordor}}: A spooky world from which the monsters come from appears in gateways around town.
* NoFourthWall: All references to content locked away in the trial version are lampshaded.
-->Perhaps the full version will be a bit kinder to the fourth wall.
* OffscreenMomentOfAwesome: Your brilliant plan for getting down from a stuck ferris wheel. See HandWave above.
* ParentalBonus: InvokedTrope. Tasha Harris wanted the game to have the appeal that Creator/{{Pixar}} (her former and now current employer) applies to all their work, in which the game would be simple and charming enough for children, but also appealing to adults. There are plenty of jokes for adults, covering such edgy material as globalization, prescription drugs, American history, and more.
* PunctuatedForEmphasis: *lightning* '''TRICK OR TREAT!'''
* PunnyName: [[ExactlyWhatItSaysOnTheTin Big Bones]], the BigBad, is a ''[[FatBastard big boned]] GrimReaper.
* RecurringBoss: Bojonn.
* RuleOfCool: The magic of the costumes is never explained, but who cares?
* PatrioticFervor: The Art/StatueOfLiberty's Combat Ability, and winning animation.
* SavePoint: Telephone boxes let you call the police and tell them about the monsters. They will [[PoliceAreUseless sigh]] and tell you "your report has been logged."
** The DLC changes the dialogue for the boxes so that you're now calling the Trowbog Historical Society. Because how else are they going to know if history is happening?
* SequelHook: [[spoiler: The DLC leaves the main characters lost in a hub of portals to different worlds.]]
* ShoutOut: The [[VideoGame/RobotUnicornAttack Unicorn Costume.]] Its special attack is called [[WesternAnimation/MyLittlePony My Little Panacea]].
** The music in the mall camping shop is the camp music from ''VideoGame/{{Psychonauts}}''. The cardboard cutouts outside the shop are a cougar and a bear, just like the ones roaming Whispering Rocks in the game.
** The incantation used to open the Gate in the third area is [[VideoGame/{{Psychonauts}} Zanotto Vodello Loboto.]]
** Two more ''VideoGame/{{Psychonauts}}'' references are on the first page of the trading card list: The first candy listed is "Raz-Ums", named after the protagonist. On the same page, there is a type of cotton candy/candy floss that resembles the FunnyAfro of JerkJock Bobby Zilch.
** The Pumpkin Costume's battle form is ripped straight out of ''WesternAnimation/TheNightmareBeforeChristmas''.
** The Disembodied Hand Stamp upgrades into the [[Film/ThePrincessBride Disembodied Six-Fingered Hand Stamp]].
** The cowboy warning the public about the dangers of candy? [[Film/{{Clerks}} He works for an apple company.]]
** [[Series/ArrestedDevelopment "Like the kid in the $600 Banana is gonna follow the kid in the $20 costume. COME ON!"]]
** A mission in a corn field maze is called [[Franchise/ChildrenoftheCorn Children of the High Fructose Corn Syrup.]]
** Orzo the human cannonball makes references to the [[VideoGame/TheSecretOfMonkeyIsland Fettucini Brothers]].
** Finding a girl hiding in a witch costume causes her to shout "[[Film/TheWizardOfOz Oh, what a world! What a world!]]"
** [[WesternAnimation/TheNightmareBeforeChristmas It may be a stretch, but there might be a reason why the DLC for this Halloween game is Christmas-esque.]]
** An incredibly obscure one: One of the girls dressed as a witch in the mall is named April, and refuses to do love potions "for charity cases". There's a Creator/RayBradbury short story called "The April Witch" which is about a young witch trying to spread love around out of charity.
** The Robot Costume's battle form somewhat resembles Anime/{{Xabungle}} in color scheme, wings and overall appearance although both of its attacks are pretty different.
* ShrunkInTheWash: In the DLC the yeti monster turns out to be a guy in a suit; the reason why the yeti hasn't been seen is that the suit shrunk in the wash. Fortunately it's shrunk to the correct size of a 4th grader.
* SiblingRivalry: Wren vs Reynold.
** And [[spoiler:Dorsilla vs Dorian. Dorian obviously losing.]]
* SinisterScythe: Big Bones' weapon. [[spoiler:It's also where he hides his emergency candy stash.]]
* StandardStatusEffects: Poison, Burn, and Stun. Different kinds of attacks inflict various degrees of each.
* TheStarscream: [[spoiler: Dorsilla, to Big Bones.]]
* StatusBuff: Different abilities or Battle Stamps grant Ability Up, Protect, Regeneration, or the ability to evade all attacks for one turn.
* StealthMentor: [[spoiler: Dorian]]
* StockAesops: Family is Everything.
* SugarBowl
* SweetTooth: Candy is currency for upgrades
* {{Tengu}}: Crestwailers are basically Tengu.
* ToothyBird: The Crestwailers are this.
* VillainousGlutton: Big Bones.
* WhatTheHellHero: The player makes a [[JerkWithAHeartOfGold grudging but heroic speech]] to Dorsilla's voicemail. [[spoiler: She clips out the heroic parts for her own purposes.]]
* WickedWitch: Dorsilla.
* WhatMeasureIsAMook: Metxel crashes his Candy-dozer into two mooks in the middle of a fight.
-->'''Metxel''': Now look what you made me do! One of them was my brother-in-law!\\
'''Wren''': Which one?\\
'''Metxel''': I don't know! They all look the same to me! Just like humans!
* WomanScorned: [[spoiler: When Big Bones discovers Dorsilla's plot to usurp him, he breaks the deal with her and tell her to get lost. Not happy at all, she obeys, but not before boosting the heroes' power so they'll kick his ass.]]
* WrongGenreSavvy: Lucy, big time. Spouts a lot of science fiction (and science fact) in a magical setting.
* YouMeanXmas: Yeti Fest is a cross between Christmas and Groundhog Day.
* ZipMode: The starting (robot) costume's special ability is a dash mode, allowing you to rocket around the neighborhood and save time. It's also necessary to get over ramps.

[[folder:Costume Quest 2]]
* AbusiveParents: "Psychobitch" is still a too nice word to describe Orel's mother.
* {{Anticlimax}}: At least for the {{cliffhanger}} of the previous game's ''Grubbins On Ice''. With the kids stranded in a portal network, this looks like it would lead into an adventure where they jump between worlds to find a way home... but the first portal they take happens to drop them into their neighborhood.
* AfterCombatRecovery: Averted. You no longer regenerate all your health after battle; whatever damage you take is carried over to the next battle unless you visit the [[SavePoint healing fountains]] in between.
* AnimalEaredHeadband: Available as an upgrade for the pharaoh costume.
* AscendedExtra: The candy corn costume that was the cause of the sibling's kidnapping in the first game is here a real battle costume!
* TheAtoner: Travis, the head of the mummy gang, seems to have matured a lot in 20 years. He even admits that he was a jerk as a kid.
* BadFuture: A world where "Overlord" Orel White has banned any trick-or-treating or candy consumption under penalty of martial law, enforced by clacking robotic teeth drones that patrol the city, and routinely ships off disobedient children to gruesome dental re-education centers.
* BagOfSpilling: All of your sweet costumes from the previous game disappear due to a time paradox once the plot gets rolling.
* TheBigEasy: The past section takes place in an obvious NoCommunitiesWereHarmed version of New Orleans.
* TheCameo: [[spoiler:WebAnimation/BeeAndPuppycat appear in the Top-Secret Warehouse, with Puppycat even making the same Vocaloid noises. The credits later thank Natasha Allegri.]]
* CallBack: In [[spoiler: Orel's fake Halloween warehouse, all the fake kids are painted in the costumes from the first game. Except for one, a ShoutOut to Raz from ''Psychonauts'']]
* ClothesMakeTheSuperman: Again. The new costumes include [[AscendedExtra Candy Corn]], {{Superhero}}, [[NonIronicClown Clown]], [[{{Pterosoarer}} Pterodactyl]], UsefulNotes/ThomasJefferson, [[WizardClassic Wizard]], [[{{Mummy}} Pharoah]], [[spoiler:{{Wolfman}}]], [[spoiler:[[OurGhostsAreDifferent Ghost]]]], [[spoiler:Hot Dog]], and [[spoiler:Solar System]].
* CounterAttack: You eventually gain the ability to counter enemy attacks. The timing is trickier than a standard block and requires some reading of enemies, but if you pull it off you greatly reduce the damage and deal some in return.
* CreativeClosingCredits: They play as you explore Auburn Pines in the present and catch up with everyone there.
* DepravedDentist: The BigBad, Dr. Orel White (D.D.S.).
* EarthShatteringKaboom: [[spoiler: The Solar System costume's LimitBreak. A bunch of spaceships surround Earth and fire simultaneously, rendering it a blackened wasteland. Don't worry, all it does in-battle is massive damage to your enemies.]]
* {{Expy}}: Some of the new costumes borrow their out-of-battle movement abilities from the first game; the Wizard can light up areas like the Spaceman did and the Pharoah takes over sliding down ropes from the Pirate.
** Like some of the first games' costumes referenced other Double Fine games, the boys' version of the Superhero costume resembles Sweet Justice from ''VideoGame/MiddleManagerOfJustice'', and its special attack is even ''named'' Sweet Justice. The girls' version, though with the same outfit and special attack, resembles Surge Protector from the same game.
* FutureMeScaresMe: [[spoiler: Kid!Orel's reaction to his adult self.]]
* GenderBender: When Wren or Halley are wearing the Clown, Thomas Jefferson, Wizard or [[spoiler:Wolfman]] costumes they have to transform into remarkably male looking characters to fight.
* GenderedOutfit: The Superhero is the only costume in the game who has male and female version.
* GuestFighter: The [=PS3=] and [=PS4=] versions include ''VideoGame/LittleBigPlanet''[='=]s Sackboy as an exclusive costume.
* GuestStarPartyMember: Three kids take the role of third PC during the game:
** Monty, a would-be gator tamer.
** Halley, Everett's and Lucy's daughter.
** [[spoiler: Kid!Orel.]]
* InfinityPlusOneSword: [[spoiler: The Solar System costume. There's nothing in-game leading you to it and it requires you to pick up some other optional costumes, but it's extremely powerful, with very few drawbacks.]]
* JokeCharacter: The candy corn costume can't attack, as you'd expect from a giant inanimate piece of candy just sitting there. The only good it can do is serve as a damage sponge to deflect enemies' attention.
* MeaningfulName: Orel is a homonym of oral, and white is the desired color for teeth. It makes for a fitting name for a dentist.
* OfficialCouple: After being [[{{Kidanova}} exceptionally flirty]] when they were little, Everett and Lucy are eventually revealed to have gotten married in the future. And to have a daughter.
* PlayableEpilogue: While the credits roll, you can explore [[NostalgiaLevel Auburn Pines in the present]] and talk to everyone here. That includes an explanation to the WhamShot and an appearance of Zac Gorman.
* PreOrderBonus: Pre-ordering the game on Steam got you four costumes from the previous game to use: Robot, Pumpkin, Unicorn, Eyeball.
* SetRightWhatOnceWentWrong: It's up to Wren and Reynold to fix the candy-less future Orel created.
* ShoutOut:
** One of the Trowbogs, a dimwitted fellow with [[ThirdPersonPerson poor grasp of personal pronouns]] named Mongo, is [[Film/BlazingSaddles tricked by the kids with a false Candygram]].
** The Wizard costume is clearly inspired by [[{{Literature/TheLordOfTheRings}} Gandalf the Grey]], complete with its upgraded form being white.
** A kid in a Devil costume [[AtTheCrossroads at a crossroads]] challenges you to play his fiddle against your... clown horn, a reference to ''The Devil Went Down to Georgia'' by The Charlie Daniels Band.
** The [[spoiler:Wolfman]] costume references [[spoiler:''Film/TeenWolf'']], especially when upgraded. It also has the ''Music/{{Thriller}}'' [[MichaelJacksonsThrillerParody dance]] as its victory pose.
** The upgraded [[spoiler:Ghost]] costume is green and ends up looking like [[spoiler:Slimer from ''Franchise/{{Ghostbusters}}'']].
** The Monument in the Future Square bears a resemblance to the Worker of Korea's Party Monument in North Korea, if only in the hands.
* StartOfDarkness: Not only is Orel's miserable childhood revealed in the past, but we also see a young Big Bones, back when he was only a child in a skeleton costume and not an enormously fat Grim-Reaper-like ghost demon. [[spoiler:His eyes even light up in the same way when wolfing down candy, hinting at the addiction which presumably caused his early demise.]]
* ThisLooksLikeAJobForAquaman: [[spoiler: During the final fight against Orel, the Candy Corn costume can use its LimitBreak: "Glisten", which causes Orel to lose his turn.]]
* TimeyWimeyBall: In the intro, the kids note that they arrived back home at Halloween even though they left (in ''Grubbins on Ice'') in the middle of winter. Lucy insists it can't have been time travel; it must have been temporal something-or-other.
* WhamShot: The very end of the game, Halloween is saved, all is well that ends well... [[spoiler: And a '' '''Grubbin''' '' comes in view.]]
