In order to receive their allowances ahead of time so they can buy a new scooter, the nephews trick Scrooge into believing it's Saturday instead of Friday, resulting in mass confusion worldwide.
This episode contains examples of the following tropes:
- An Aesop: What seems like a small, harmless lie can quickly snowball into something much worse.
- Banana Republic: The Central American-esque country run by the militant dictatorship where Scrooge's cereal factory resides in is literally called the Banana Republic.
- Brick Joke: Fenton has to borrow a dime from Scrooge so he can use a pay phone to get ahold of the Gizmoduck suit. Then, after they're out of danger, Scrooge calls to him and Fenton answers, knowing Scrooge wants the dime returned.
- Clock Tampering: The boys alter all the calendars in Scrooge's mansion to make him think it's one day later. Unfortunately, when Scrooge McDuck thinks it's Saturday, the whole world must follow suit...
- Gaslighting: Effectively what the nephews end up doing to Scrooge, and by extension, the world.
- Get It Over With: Fenton's way of drawing his "last words" out to buy time for his Gizmoduck suit to arrive annoys everyone so much that Scrooge would rather prefer to be finished off rather than have him stall for another second.
- Laser-Guided Karma: The nephews' plan to buy the scooter before the sale ends winds up backfiring for them. While their ploy to get their allowances early works, due to everyone now thinking it's Saturday the sale on the scooter ends, which means even though they now have their allowances they no longer have enough to afford it!
- Moral Dissonance: Scrooge does business with the military dictator of a Banana Republic (literally called "The Banana Republic"). Though the dictator is portrayed as a villain who attempts to execute Scrooge and Fenton at one point, Scrooge having done business with him is never portrayed as a bad thing.
- A confused Fenton says, "Right now I'd be happy if it was Tuesday and this was Belgium!", which refers to If It's Tuesday, This Must Be Belgium.
- Fenton also references Nathan Hale's last words and Marc Antony's "friends, Romans, countrymen" speech.
- Total Eclipse of the Plot: An eclipse turned out to be the proof needed by the triplets to show that they had pranked Scrooge into thinking it was Saturday so that he could give them their allowances early.
