* PaperThinDisguise: It's not exactly a surprise to discover the talking dog and obviously malevolent Nik Nokturne is a Beagle Boy.
** All of the guests are in paper-thin disguises. Yes, it was a costume party, but it didn't take much to figure out who was who.

** The security system in [=McDuck=] Manor is labelled "DT-87", referring to the year the original DuckTales aired.

** The security system in [=McDuck=] Manor is labelled "DT-87". Gee, does it really take a genius to know what that refers to.

* CallBack: Mark Beaks gets dropped off a building just like in his debut episode. [[spoiler: This time it's by Duckworth's ghost, and it's only a fall of a meter or so.]]

* OnlySaneMan: Louie is a ZigZagged example in this episode. On the one hand, he's the one suggesting that the triplets stop forcing Scrooge to celebrate his birthday with a party and, after he gets kidnapped, trying to convince Huey they should call Mrs. Beakley or the police for help. On the other hand, he was the one who invited Scrooge's RoguesGallery to the party in the first place.

* BirthdayHater: Downplayed in Scrooge's case; he doesn't hate his birthday, but he doesn't like the fact that he's older than everyone he knows being celebrated - he prefers a single day of doing absolutely nothing. As a result, everybody gives him space so he can have the day to himself (for example, Beakley and Webby use his birthday as an annual survival skills trip and Donald simply fled in terror).

* HeroAntagonist: As it turns out, Duckworth sealed the party away from Scrooge and took him out of the mansion to relax; Huey realizes he wouldn't have done anything were it not form him setting up the party to begin with.

* JerkassBall: Huey grabs it by unilaterally deciding to plan out the entire night and refusing to consider anyone else's thoughts or feelings on the events that transpire.

As a result, everybody gives him space so he can have the day to himself (for example, Beakley and Webby use his birthday as an annual survival skills trip).
* TheButlerDidIt: Parodied brutally twice. First, when Blackarts Beagle is revealed as the criminal, it is done in the most obvious, over the top way, complete with him being visible in position summoning insane magical power while Huey fails to realize he's forgotten a suspect, as Blackarts Beagle is just supplementary to the plan. Secondly? Well...Duckworth did it.
