The [[ExactlyWhatItSaysOnTheTin 2011 Halloween event for]] ''Manga/AxisPowersHetalia''. It's Halloween in the Hetaliaverse, and [[IdiotHero America]] is having a costume party! Japan is worried about the food coloring (as usual) but America assures him that they stopped ''[[{{Squick}} using actual blood and gore]]'' since Lithuania had such a hard time cleaning up last year. We then see all the nations arriving in their respective costumes.

[[http://hetarchive.net/scanlations/hall2011/index.php Scanlations of the event can be found here.]] Tropes below relate to both the comics and the fan responses.

!!This event provides examples of:
* AwesomeButImpractical: America, you're my country and I love you, but why are you hosting a big ass party with a giant stage and projector screen when we're recovering from a recession?
** Probably pushed all the expenses onto another, more financially advantaged, country like he did to Japan for a Christmas party in the anime. Other options are [[AlternateUniverse AU]], RuleOfFunny or RuleOfCool.
* BigEntrance: [[spoiler: India ''owns'' this trope.]]
** Does [[FanNickname Grandmano]] count here as well?
** [[spoiler: America waited all night just to do this.]]
* [[spoiler: DarkHorseVictory: The winner of the contest [[TakingAThirdOption wasn't any of the teams but Vietnam's team]], what about that!]] [[http://hetarchive.net/scanlations/hall2011/hall20115.php See for yourself!]]
* DraggedIntoDrag: Hungary takes ''way'' too much pleasure in putting Austria in a dress (he wore the costume under the condition that he wears pants while dressed in it.)
* ChekhovsGun: England [[spoiler: writing on America's twitter. Yes, that wasn't just a throwaway joke!.]]
* CliffHanger: [[LastEpisodeNewCharacter Someone]] shows up when the party is over. We just don't get to see who.
* ContinuityNod: England saying America won against him this year refers to [[http://aph.starry-sky.com/hllp.html this strip]].
* CostumePorn: DUH. Sherlock!England, Francer Pan, Captain Cook!Seychelles, Tinkerbell!Monaco, Toy Story!Micronations, pirate!Nordics and Wonderland!Soviets to name a few.
* CostumeTestMontage: Italy tries out a variety of different costumes, but none suit him due to lack of muscles. He finally settles on [[BrickJoke dressing as a prisoner]]
* FanService: Well, this ''is'' Hetalia, so...
** New characters, awesome and sexy costumes, HoYay, cute moments...everything you could ever want from an event!
** [[MindScrew Everyone who came into contact with Germany ends up (dressed as) a slave.]] None of them seem to mind.
*** [[spoiler: Eventually he ends up in the costume too. Turns out it was Grandpa Rome want to spread Italy's look around.]]
* FanNickname: A new one for Hima-sensei is "Alpacaman", because [[WildMassGuessing apparently HST is due to him secretly being a superhero and having to frequently go out to save kittens/alpacas]].
** Also "Stop-Bitch" for the guard who stopped [[AmbiguouslyGay Poland]] from bringing a horse to the party.
** [[http://pics.livejournal.com/pyrolynx/pic/000095k1 Don't forget "Thigh-bitch" for the guy staring at Belarus's thighs.]]
* FlippingTheBird: Belarus to Denmark. Mochimerica to Russia. Romano in the text message for Luxembourg.
* {{Foreshadowing}}: [[spoiler:The Batman logo on America's suit. Guess what his costume turns out to be?]] Funnily, in spite of furious speculation about what [[spoiler:America's costume would be]], almost ''no one'' noticed this!
* FoodEnd: At the end, everyone is just happily drinking, chatting and [[ItMakesSenseInContext dressed like slaves.]]
* HalloweenEpisode: Rather obviously.
* HotBlooded: Belarus when it comes to her brother's costume being the best, which leads to:
** ImprobableWeaponUser: She throws a hanger at Denmark for daring to say that he'll win the costume contest.
* ImpossiblyCoolClothes: Cameroon's costume is a ScaryImpracticalArmor with a [[FireBreathingWeapon flamethrower]]. '''A flamethrower!'''
* ItWasWithYouAllAlong / AssPull: England didn't know about the costume contest because America put the notice for it ''behind his ear''.
** Also, we finally found out who was responsible for all of the slave costumes: [[spoiler: Rome]].
* NoticeThis: England found a piece of paper. [[spoiler: It turns into a ChekhovsGun when we see what it says.]]
* NotWhatItLooksLike: Taiwan went to ask Japan what he thought of her costume and found him with Germany checking the lightness of the shackles. [[HilarityEnsues She ended up seeing nothing but weird stuff]] [[spoiler:and being told she looked cute]].
* PermaStubble: [[DyeingForYourArt France shaves his off]] and rubs his face against England's.
** And he spontaneously grew it back. Yes, England was indeed confused.
* ProductPlacement: Belgium as Red Riding Hood mentions that a video game based on one of her horror stories called VideoGame/ThePath is on sale. Also, Iggy made a sarcastic comment on America's twitter, and was his first follower. Also, the prize for the costume contest that England doesn't know about is ''[[VideoGame/Uncharted3DrakesDeception Uncharted 3]]''.
* RealSongThemeTune: [[http://hetalia.livejournal.com/11683199.html Thanks to a certain LJ user]] people can now sing hetalia-lized versions of popular songs as they wait for updates.
** [[http://hetalia.livejournal.com/11686520.html#cutid1 Here's some more!]]
** [[http://hetaweentrollf5fied.tumblr.com/ And the Tumblr Masterlist!]]
* [[SheCleansUpNicely They Clean Up Nicely]]: Pretty much ''everyone'' does this. Of special mention are: Taiwan as the virtual idol ''[[http://nihao-meimei.tumblr.com/post/12345146209/taiwans-halloween-costume Silverlight]]'', Wy in a cute doll-like dress, Hungary as [[{{Bifauxnen}} a handsome Prince]], the Slavic/Baltics as an Literature/AliceInWonderland ensemble, the Nordics as pirates, and [[spoiler: India and Prussia]] in [[SharpDressedMan suits]].
* SpontaneousChoreography: Courtesy of [[spoiler: India and Prussia.]]
** [[spoiler: Actually, Prussia's twitter said he'd been practicing for a month.]]
* WhenSheSmiles: Belarus [[spoiler:when she accepts her defeat to Vietnam's team and decide to cease her fight with Denmark]].
