History Recap / MiraculousLadybugS03E20PartyCrasher

* TheLastOfTheseIsNotLikeTheOthers: Apparently, the Monkey Miraculous is special enough to make Fu think twice before giving it to someone. He ultimately chooses to trust Kim. This pays off.

* NiceJobBreakingItHero: Max uses his robot Markov to take over the electrical system of the house and crank up the music volume for the party. This turns off the life support for Emilie Agreste, causing Hawk Moth to summon an akuma in sheer self-defense.

* LockedOutOfTheLoop: The Gorilla would never have permitted the party if he knew Gabriel was actually at home, showing that he doesn't share the secrets of Hawk Moth as [[SecretKeeper Nathalie does]]. Given the nearly deadly power outage that developed, this is also an example of PoorCommunicationKills.

** The titular villain is called "Party Crasher". He was akumatized because he was literally the only one to ''not'' crash the party.

** Roger, other adults, AND a poorly disguised Marinette do a ''Village People'' cover.

* ContinuityNod: Marinette once again makes a disguise from trash she finds in a dumpster to get into a place where she is denied entrance. The costume itself is very similar to the one she created in [[Recap/MiraculousLadybugS01E23PrincessFragrance "Princess Fragrance"]], with a motorcycle helmet and a poncho-like garment.

* TheBusCameBack: Wayhem is seen for the first time since "Gorizilla".

* BrickJoke: Mayor Bourgeois shows up to the party to hide from Chloé’s attempts to put make up on him. Later during the montage, Chloé herself shows up looking for him, immediately followed by an equally in-need-of-hiding butler Jean.

* PoorCommunicationKills: A lot of the episodes problems are due to misunderstandings. Adrien tells Wayhem he's busy and not allowed to have any friends over because he had no idea Nino would throw a surprise party and as a result Wayhem thinks he lied to him and is upset enough to get Akumatized. Meanwhile, Nino tells Gorilla to keep Marinette out and refuses to answer phone calls because he thinks she wants to bust them for backing out of their plans to plant trees when, in fact, she really just wants to join in the party. Also happens almost literally when Adrien lets Max mess with the house's power systems not knowing his mother was in a life support capsule underground that very much needs that power.

** Marinette chides Master Fu for going to the party and not being safer with the Miraculous box, to which Fu replies that they're perfectly safe because he has them with him. [[DramaticIrony Neither are aware that they're]] ''in Hawk Moth's house,'' probably the least safe place in the city.
** Make it painfully double to Gabriel: He not only created one of his most efficient villains that almost gave him the ultimate triumph, but ''all of the Miraculous were in his house, ripe for the taking'' and he had no idea... all of that when he intended to ''take a day off''!

* LoveMakesYouDumb: Cat Noir doesn't even listen to Fu's advice after Ladybug is caught in Party Crasher's curse.
* MonkeyKingLite: Kim's Miraculous form, King Monkey. He carries a staff, his Uproar chaotically disrupts others' powers, and the Miraculous itself resembles the Golden Ring Headband. This is actually justified, as the Miraculouses are said to have been made in China and that Sun Wukong himself was a previous holder of the Monkey Miraculous.

* OneHitKill: Party Crasher can capture any person or object by touching them with a disco-ball hand, or hitting them with a beam at a distance. They are caught on one of the mirror facets of the ball.

** [[VideoGame/SuperMario64 "It's-a me, Marino!"]]

** Marinette wears a Groucho mask as diguise. A Looney Tunes specialty.
* StrangeMindsThinkAlike: Marinette tries calling Ivan to find out whether the boys are having a party and Nino stops him from answering “because he [[BadLiar can’t lie to save his life]]”.

* UnwittingInstigatorOfDoom: The Gorilla's actions ''really'' had some effects he couldn't have predicted - letting Adrien's friends in and allowing their party causes Markov to redirect power that was going to Emilie's life support that the Gorilla didn't know about. He also saddens Wayhem into akumatization by not letting him in like all the other guys just because the Gorilla happened to be wearing earplugs and playing with his action figures while Wayhem was there...which inversely actually saved Emilie's life since Party Crasher did as he's named where otherwise the party probably would have kept going for a while.

* WildTeenParty: {{Downplayed|}} - despite practically the entire male cast of the show eventually getting in on it, little openly disastrous happens from the party itself aside from Markov redirecting power from Emilie's life support unbeknownst to anyone there (which actually started happening when it was only just the six boys there). The only typical trouble is Roger saying they were a noise violation...after which he joins the party, though an akuma appearing at it turns out to be a big problem. The party also gets adults having fun there pretty quick.

* ComicallySmallBribe: The Gorilla lets people into the house he is supposed to be guarding when he is given toy action figures. {{Downplayed|Trope}} and {{Justified|Trope}}. Given that it's fourteen-year-olds who are bribing him, they still find forking over three action figures to be a bit of a hard bargain and the Gorilla likes to see Adrien happy, so he doesn't need much excuse to let Adrien's friends in.

* WorfHadTheFlu: A very rare instance where Ladybug is incapacitated before Cat Noir. [[DoubleSubversion Contrary to what you'd expect]], that doesn't prompt Cat Noir to solve the problem, but King Monkey does, instead.
