Even a kid might have a vague idea you shouldn't store all of your money as pennies and keep it in a single building for the sole purpose of swimming through it, and an older person with more knowledge of real-world economics would realize it even less sense — Scrooge knows about this. He is so freakin' rich he can afford to keep his funds liquid and inefficiently stored like that.
Furthermore, those funds are literally 'liquid'. As in 'the usual contents of a swimming pool'.
Everyone tends to have loose change that they likely keep in a piggy bank or in a jar. Scrooge McDuck is so rich that he needs AN ENTIRE BUILDING to hold his loose change! The fact he can swim in it is just a plus. -Game Guru GG
There's a more practical reason for Scrooge's moneybin. Scrooge is so ridiculously rich that if he actually spent or invested all his money, he would destroy the world economy with a lethal level of inflation! By keeping so much of his money in his money bin and out of circulation, he avoids global economic devastation. At the same time, whenever he feels like shocking someone with a little fiscal "dragon awe", he has immediate access to his gazillions. -me
"Coins are only valuable when they're rare... and Scrooge McDuck is the one who makes 'em rare!" (Don Rosa, "The Money Pit")
You're 40 years late. The original quote "And I'm the guy that makes 'em scarce!" comes from "Money Pit"s predecessor, the 1951 Carl Barks comic "The Trouble With Dimes". He's also the guy who thought of a money bin in the first place, back in '51.
El Capitan was once, as his title implies, the captain of the ship full of gold that Scrooge and the boys discover in "Treasure of the Golden Suns: Part 2." It's never stated outright, but when the "Old Wheezer" is taking inventory of the ship, one of the triplets remarks, "Boy, he's actin' like he used ta own this ship!" Plus, later on, in Part 5, we find find out he's at least 400 years old. Well, just today this troper was watching Part 3, where the conquistador Joaquin Slowly explains his family history - how, 400 years ago, his ancestor Marching Slowly looted the Valley of the Golden Suns with a traveling companion, but the captain of their ship abandoned them and sailed away with the spoils. We then get a shot of the ship's captain - and it's a dog character who looks very much like a younger version of the El Capitan we're familiar with.
So, he's a Highlander?
Scrooge hiring Fenton as his accountant makes a lot more sense when you remember Scrooge's own Rags to Riches origins. It's likely he (Scrooge) didn't have any real schooling or any kind of higher education, but he made it anyway by being tough and smart. Fenton shows up at his office, refuses to take no for an answer and just keeps coming back no matter how many times Scrooge tries to get rid of him. So he's tough. Then he shows off his incredible counting skills. So he's smart (or at least talented). It's quite likely Scrooge saw some of himself in the plucky young duck and so was much more willing to give him a chance.
In DuckTales: Remastered, the music extras use a screenshot of the level that each song represents imposed over an image of sheet music. That sheet music background looks familiar...
Also from DuckTales: Remastered: Of the two types of gemstone you can collect—rubies and diamonds—the former give more money. Counter-intuitive, you say? Ah, but you forget...the world is full of diamond mines in real life; the market simply controls their distribution to make them seem more valuable. Rubies, by comparison, are rarer.
It's not really counterintuitive. Diamonds are symbolically associated with wealth, but rubies have always been more valuable and priced higher.
Launchpad is known as theCaptain Crash; as he says, "If it has wings, I can crash it!" However, he usually has better luck with helicopters, as the majority of the time, when he's piloting a copter, he lands just fine. Well, of course he does! Helicopters don't have wings!
According to Launchpad, Scrooge is actually a pretty good cook. He did spend a lot of time out in the Klondike, and would not have been eager to pay for anyone to cook food when he could do it himself.
Why would the men and women stop arguing over who was going to lead the rescue mission when Launchpad took charge of it? Because it's a third option that allows both of them to do what they want (rescuing Grunta) while not backing down from their positions. The men aren't giving in because Launchpad is a male, and the women aren't giving in because Launchpad isn't one of their men with whom they're having the argument.
While Launchpad's...unique flying style can partially be explained by his Cloud Cuckoolander tendencies, there is another potential explanation. Launchpad was probably taught how to fly at least partially by his parents. Launchpad's flying the way he flew as a member of the Flying McQuacks, like a barnstormer, not like a private pilot.
Why are there Beagle Boys in the African Mines in the game? Simple: They're working for Glomgold who, being an Africaaner himself, owns the mines.
The theme song for DuckTales has always gone on about 'rewriting history'. DuckTales (2017) and DuckTales Remastered both LITERALLY rewrite history, the latter by completely rearranging the original game and fixing several glaring errors, including it's "Blind Idiot" Translation, to make a functionally identical game, but with a much more understandable play style.
In DuckTales Remastered, it suddenly makes a lot of sense why the Beagle Boys show up in nearly every single level, despite fleeing from the Money Bin without the treasure map in the first level. They work for Glomgold, who works with Magica, who made that map and sold it to Scrooge in the first place. She knew where to sent them already.
In the original DuckTales NES game, in order to enter the African Mines, you first have to retrieve the key in Transylvania. It seems like pointless padding, until you find out at the very end that Glomgold, who made his fortune with African mines, and Magica, who practically made the Transylvanian mansion into her lair in the game, were working together all this time.
Duckworth is the only non-duck character with a duck-related surname. But there's a valid reason for this; Duckworth is a hound, and hounds are used in hunting, often for the retrieval of waterfowl. A good hunting dog could be said to be "worth his ducks" the way we might say an employee is "worth his salt." What is Duckworth's primary role? He's Scrooge's chauffeur. His job is to go retrieve ducks.
When explaining the French restaurant incident in "The Status Seekers", why does Scrooge admit that he and Launchpad are friends rather than just saying that Launchpad is his pilot? Because the only thing that would make the Status Seekers lose respect for him more than saying Launchpad is a friend would be admitting that he would actually deign to have lunch with one of his employees!
In Luck o' the Ducks, the Banshee and the Dullahan are subtly implied to be a couple; this makes sense, since both entities are Irish psychopomps.
In "Send in the Clones", Bigtime Beagle thanks Magica de Spell for breaking him and his brothers out from their life sentence. Considering the kind of serious crimes that would normally incur such a punishment, this paints the Beagle Boys in a far darker light than usual.
In "Nothing to Fear", Scrooge gets thrown out the window by the evil versions of his nephews conjured by Magica. It would be easy to assume that maybe Magica's sorcery created the magical equivalent of Hard Light holograms, except that later Scrooge wanders in on Doofus struggling with his own fears, and there's nothing there. That means that whatever Magica's illusions do to a person, they do something like that to themselves. Everyone was lucky their fear illusions didn't resort to anything too violent.
A heavy dose from "The Golden Fleecing", in which Launchpad is nearly killed by a dragon. Just try not to think too hard about what happened to the other people who happened on the island or came there hunting the fleece.
"A DuckTales Valentine" introduces Aphroducky's love arrows, which make a person fall madly in love with the first being seen after being stuck, to the point of ignoring important personal goals and even personal safety. That in and of itself is a horrifying concept, but what if someone had gotten ahold of them who would actually use them for their own benefit (rather than just keeping them as a trophy like Scrooge)?
In the episode "The New Gizmo Kids On The Block", how could Fenton fit his Gizmo suit into his washing machine, why would you put a metallic suit into a washing machine, and how could it shrink in the first place?
It was actually Fenton's mom who washed it, just throwing everything into the washer without checking it (still doesn't explain why the suit was among the laundry). And it shrunk because it was a special "polyester aluminum blend." Yeah, it makes even less sense now.
In "Wrongway to Ronguay," how did Scrooge and his nephews manufacture golden planks so quickly? But even if we accept that ... they patched up the ship's holes with gold but didn't do so symmetrically. What happens to a ship when one side weighs WAY WAY MORE than another?
It's not the weight of the vessel that matters for balancing and floating the ship, it's buoyancy that's really important. So long as the density of the hull remains balanced, the ship will remain level in the water due to the downward pressure. If for any reason the ship's buoyancy changes (IE, one half of the ship begins taking on water, adding mass to that side and altering its density) and develops a list, you can compensate by either counter-flooding (a real damage control technique involving deliberately allowing water in opposite to the flooding side) or moving ballast.
Gold is way more dense than wood. While there wasn't enough to cause problems it should have at least been leaning to the side a little and control might be affected.
In "Scrooge's Last Adventure", Fenton invests all of Scrooge's money into a computer banking system, only for it to get lost to a glitch. Do they call customer support? Nope. Instead, Gyro sends Scrooge and Fenton into the computer and they defeat the glitch-monster, which restores Scrooge's money. IN CYBERSPACE. Somehow, Scrooge's cash was digitized when the Money Bin was emptied out. Gyro then directs Scrooge, Fenton and the money to a computer at the Bin, where they literally break out of the computer screen to return to the real world, as opposed to using Gyro's digitization machine.
From DuckTales: Remastered, Scrooge will sometimes comment (upon picking up large gems) that he's "never seen a gem like this before." And yet, you've likely been picking them up left and right up till that moment...
In the original NES game, there's a moment where Scrooge rides in a cart with his nephews, and the player has to get Scrooge to jump out to a nearby platform. So..... what happens to the nephews?
In the Remastered game, how could Glomgold and the Beagle Boys breathe on the Moon? We get an explanation for Scrooge, but none for his opponents.
Considering The Reveal that Magica and Glomgold were working together all along, it's likely that she used her powers to make sure they could keep up with Scrooge in space.
