History Recap / DuckTales2017S1E16DayOfTheOnlyChild

* AnAesop: Having siblings is a great thing that should not be taken for granted. At the same time, it's important for kids to spend some time apart from their siblings so they can explore their individual interests.

* DirtyCoward: When Louie tries to team up with Mr. and Mrs. Drake to escape from Doofus, Mr. Drake immediately sells him out. Mrs. Drake just reacts to her husband in complete disgust.

* AbsenteeActor: The episode focuses entirely on the kids, with no appearance of Donald, Scrooge, or Beakley (other than in the form of cardboard cut-outs as the "audience" of Dewey's talk show pitch and the former being mentioned). Launchpad makes a brief appearance as the Junior Woodchuck scout master.

* AIIsACrapshoot: The security bot. It doesnÂ’t help that Webby essentially stripped it of its inner workings so that she could fit inside, depriving it of its ability to accurately judge a given situation.

* EvilTwin: When Dewey tells Webby that he's an only child, without first informing her about Only Child Day, she assumes he's an evil doppelgänger from an alternate dimension, then attacks him and demands to know where the real Dewey is.

* GettingCrapPastTheRadar: As Doofus decides that Louie should be his friend, he reaches down his own pants[[note]]he's one of the few ducks that actually wears pants[[/note]]. He's just pulling out a friendship bracelet, but Louie is understandably freaked out.

* BeCarefulWhatYouWishFor: At the start of his segment, Huey wishes to himself that he had brothers who "blindly listened to him". By the end of his segment, he immediately regrets it.

* AbsenteeActor: The episode focuses entirely on the kids, with no appearance of Scrooge, Donald, or Beakley (other than in the form of cardboard cut-outs as the "audience" of Dewey's talk show pitch). Launchpad makes a brief appearance as the Junior Woodchuck scout master.

* AesopAmnesia: Huey sacrificed earning his cartography badge to avoid certain death but would hang out with the Beagle Boys for a cooking badge. To be fair, Huey rated working with the Beagle Boys to earn his badge as only "''possible'' death."

* BeCarefulWhatYouWishFor: At the start of his segment, Huey wishes to himself that he had brothers who 'blindly listened to him'. By the end of his segment, he immediately regrets it.

* BerserkButton: When Louie almost damages the picture of Doofus' grandmother, who gave him the money as inheritance, Doofus has a prolonged FreakOut.

* CallBack:
** We don't see him, but Louie refers to a "ghost butler," calling back to Duckworth from "[=McMystery=] at [=McDuck McManor=]." The security robot is manufactured by DT-87, the same company that made [=McDuck=] Manor's security system from the same episode.

* CastingGag: Doofus' parents are voiced by Creator/YuriLowenthal and Creator/TaraPlatt, who are married in real life.
* ChubbyMamaSkinnyPapa: Doofus's parents, Mr. and Mrs. Drake act as his butler and maid respectfully. Mr. Drake is lean and is clearly the weaker-willed of the two, while Mrs. Drake is bigger and while she doesn't stand up to their son, she does show clear disgust towards her husband's willingness to sell out Louie to save his own skin.
* CompanionCube: For his talk show pitch video, Dewey makes dummies of his brothers (a toy robot with a red cap for Huey, a lamp with a green shirt and a face drawn on the shade for Louie) and talks for them. It gets {{Lampshaded}} later when Dewey is hiding from the security drone and asks the dummy brothers for help, only for "them" to respond that they're just him and can't help.

** Webby rips a bunch of wires out of the security robot, including some of it’s processing circuts, so she could ride around inside of it. Unsurprisingly, as soon as she's not controlling the robot, it goes haywire and mistakes her and Dewey for being intruders.

* EntertaininglyWrong: When Dewey tells Webby he doesn't know who Huey and Louie are and that he's an only child, she assumes he's an evil Doppelgänger from an alternate dimension, which in this universe is actually a strong possibility.

* EvilTwin: When Dewey tells Webby that he's an only child, without first informing her about Only Child Day, she assumes he's an evil Doppelgänger from an alternate dimension, then attacks him and demands to know where the real Dewey is.

* HiddenDepths: Bouncer Beagle makes some "Junkyard Stew" when with Huey, and while the result looks terrible (to the point it contains a tin can), Huey ultimately likes the taste of it, indicating that Bouncer has some pretty good cooking skills.

* LetsGetDangerous: When the triplet's paths converge at Doofus Drake's mansion, along with their respective antagonists that can only be overcome by one of the others.
-->'''Huey''': Beagle Boys.\\
'''Louie''': Psycho rich kid.\\
'''Dewey''': Haywire robot.\\
'''Huey, Louie and Dewey''': ''[in unison]'' Brothers again? Brothers again. Triple threat!

* MythologyGag: Launchpad is a Junior Woodchuck scout master just like he was in the original show, which has not mentioned until this episode.

--> '''Huey:''' Launchpad! [[LampshadeHanging Those are the Beagle Boys in disguise]]!\\
'''Launchpad''': [[ComicallyMissingThePoint Junior Woodchuck Rule #413: Never speak ill of a fellow Woodchuck]]! Unless you don't want that badge.\\
'''Huey''': (''gasps, then whispers to himself'') Possible death...definite badge. Possible death...definite badge. Yeah, definite badge! Definite badge!

* PushoverParents: Doofus Drake's parents are so spineless that their son forced them into servitude, making them dress like a butler and a maid and follow his every order without question. They are utterly ''terrified'' of their own son to the point his father rats out Louie for even suggesting the three unite against Doofus.
* SayingTooMuch: When Dewey gets cornered by Scrooge's security bot, it's intruder warning starts to get a little too specific...
-->'''"Bot"''': [[AC: Hello intruder, you are cornered. Perhaps you shouldn't have pushed your brothers away. Maybe appreciate that fact, because certain people would do anything to have siblings. [[SuspiciouslySpecificDenial No one you know. Certain...hypothetical people.]]]]\\
'''Dewey''': ''(FacePalm)'' ''Webby'', you can come out. ''[Webby opens up the bot's hatch and nervously chuckles]''

** The robot toy that Dewey uses to represent Huey resembles one of the ''Franchise/{{Transformers}}'' as well as ''Anime/{{Voltron}}''

** This is also the Beagle Boys' shtick. Louie convinces them at the end of the episode is that fighting among each other is what makes them the Beagle Boys.

* TreehouseOfFun: Doofus' mansion is a giant, elaborate treehouse.

Dewey invents a holiday that allows the triplets to be only children for a day, each of them spending the day by themselves.

Huey goes to a Junior Woodchuck campfire cooking competition, where the Beagle Boys attempt to kidnap him. Louie attempts to befriend the LonelyRichKid Doofus Drake, only to realize that Doofus is not as nice as he initially thought. Dewey stays back at the mansion and creates a talk show video about himself, and he and Webby accidentally make Scrooge's new security robot go haywire.

By the end of the day, each triplet realizes they need their brothers more than they believed.

* AdaptationalJerkass: Verging on AdaptationalVillainy. In addition to being a spoiled brat, this version of Doofus Drake is also dangerously and creepily insane. Beyond his general look and his name he [[InNameOnly doesn't have anything in common]] with the Doofus from the previous series.

* BecauseYouWereNiceToMe: The fact that Huey treats “Tim and Timbo” a.k.a Burger and Bouncer so much better than Bigtime makes them decide to forgo kidnapping him and instead they keep hanging out with him.

** We don't see him, but Louie refers to a "ghost butler," calling back to Duckworth from "[=McMystery=] at [=McDuck=] [=McManor=]."
** The security robot is manufactured by DT-87, the same company that made [=McDuck=] Manor's security system in "[=McMystery at McDuck McManor=]".

* LetsGetDangerous: When the triplet's paths reconverge at Doofus Drake's mansion, along with their respective antagonists that can only be overcome by one of the others.
-->'''Huey''': Beagle Boys.
-->'''Louie''': Psycho rich kid.
-->'''Dewey''': Haywire robot.
-->'''Huey, Louie and Dewey''': ''[in unison]'' Brothers again? Brothers again. Triple threat!
