Gyro's latest invention, a multi-phonic duplicator, causes a disaster when Huey, Dewey, and Louie use it to duplicate a shiny new silver dollar they earned from their cleaning work as the Dirt Busters. As the now self-duplicating coins spread through Duckberg, the town is soon buried in a "cash avalanche" and inflation shoots through the roof. Together with Fenton Crackshell, the triplets come up with a brilliantly Crazy Enough to Work plan to undo what they've done by breaking the Beagle Boys out of jail to steal all the duplicated coins and put a stop to the horrible inflation.
This episode contains examples of the following tropes:
- An Aesop: Money is only valuable when it's hard to get; "easy" money leads to inflation.
- Be Careful What You Wish For: Huey, Dewey and Louie wish for lots more money but by getting it they cause such terrible hyper-inflation that it's nearly worthless anyway.
- For Your Own Good: This is Scrooge's rationale for not advancing Huey, Dewey or Louie their allowance - or giving Fenton Crackshell a raise. Scrooge claims that, if he gives them more money, they'll take money for granted, spend it foolishly, and end up homeless and begging on the street corner!
- Karma Houdini: Gyro, Huey, Dewey and Louie are never arrested for making counterfeit money.
- Nice Job Breaking It, Hero: Fenton and the nephews attempt to stop any and all bells from being rung in Duckburg to prevent the entire city being covered in coins, since the sound is what causes them to replicate. During a shooting of The Hunchquack of Notre Dame, Fenton as Gizmoduck attempts to stop the bell from being rung. He winds up crashing headfirst into the bell instead, setting it off anyway.
- No Challenge Equals No Satisfaction: The Beagle Boys just aren't having much fun with all the townspeople practically flinging their money at them. Even robbing a bank doesn't help their mood much.
- No Ontological Inertia: Items (such as toys, the furniture and equipment in Gyro's workshop, and the silver dollars) being duplicated with such a minimal expenditure of energy is a massive violation of the First Law of Thermodynamics, but that law gets massively un-violated by the end. The coins and everything else that got duplicated violently implode back into the original singular items from which they were duplicated.
- Pooled Funds: The Beagle Boys are given their own money bin in order to store the duplicated money. Unfortunately, when Burger tries to swim through it like Scrooge, he ends up hurting himself.
- Ridiculous Future Inflation: Very much at play in this episode:
- During the "cash avalanche" a newspaper is indicated to cost "only" $200.
- A lollipop costs a little girl $5,000; pulling up a wagon full of money, she says that in that case, she'll take two.
- A bus fare costs one poor schlub $10,000 in exact change, which he heaves aboard in a heavy-looking sack.
- At the dentist's office, one fellow is told the fillings for his two cavities will cost $80,000. "Well, at least some prices haven't gone up..."
- The triplets complain at one point that it cost them $30 just to use a gumball machine.
- Screw the Money, I Have Rules!: Scrooge after Fenton demonstrated Gyro’s duplicator gun on a change purse. Rather than be excited at the idea of potentially having his entire fortune doubled with the device, Scrooge was instead scared and concerned because he knows what that would do to the economy. He even tells Fenton one of his core principles as being a businessman is that he never trusts a dollar he hasn’t earned fairly.
- Shout-Out: Huey, Dewey, and Louie first attempt to solve their money problems by dressing up as Dirt Busters, complete with gray jumpsuits and at one point saying "Who ya gonna call? Dirt Busters!"
- Stupid Crooks: Even Brainy Beagle fails to realize the Beagle Boys are being snookered and can't quite figure out why everyone is being so uncharacteristically generous with the duplicated coins, though his intuition is good enough to realize something is seriously screwy with the townspeople.
- Worthless Silver Dollars:
- At one point, Scrooge is horrified to realize his entire amassed fortune of multi-quadrillions is rendered virtually worthless, there being trillions of silver dollars in just one neighbor's yard.
- One mother sweeps out a bunch of silver dollars with a broom and admonishes her children not to go tracking any more money into the house.
- When the Beagle Boys are busy stealing all the money with their dump trucks, one local housewife flags them down so she can fling another sack of money she's tossed into the garbage can onto their pile as well.
- Much to the Beagle Boys' consternation, even the local bank is all too cooperative with their looting, with the customers (who were about to be turned away from making any more deposits since they were using the bank as a landfill) and the tellers cheering at the manager's announcement that the bank is being robbed.
