In the Mario Teaches Typing games, Mario never criticizes the player for underperforming and tries to be understanding and supportive. According to Charles Martinet, that was his initiative, as he felt being negative would go against the core principles of Mario's character.

In the Mario Teaches Typing games, even if the player does badly or underperforms compared to previous attempts, Mario will try to be understanding instead of critical:
Uh-oh, that wasn't quite as fast as the last time.
Hmm, are your fingers getting tired? Mine would be by now... if I had any. (laughs)
Charles Martinet, speaking at TooManyGames Convention 2021:
I got this marvelous opportunity to do Mario Teaches Typing. And when I got the script and I'm in the studio - I'm reading the script for the first time, there were things like "You failed!"
"That wasn't very good." "That was much worse... that was bad."
And I was reading that and I said, "Do you mind if I just, like, play with these words a little bit and just change them around?" because, you know, I never say "no" and I never say anything negative as Mario... and the producer graciously said "Sure, go for it!"
And so it became "Oh, that was good, but I know you can do even better!" "Oh, nice one but let's try again!" so it was always uplifting and always trying to be positive. And I think that that is the essence of the character to me - it's that love and that joy.

Donkey Kong 64 contains unused text that would have referenced the Gold Skulltula sidequest from The Legend of Zelda: Ocarina of Time as a joke explanation for Donkey Kong not being able to do something.

(mockup screenshot using text extracted from files)
HEY, DONKEY, YOU'LL NEED 100 SKULLTILLEYS IF YOU WANT TO RACE ME!
Donkey Kong 64 contains an unused line of text for the seal in Gloomy Galleon where he tells Donkey Kong that he needs "100 Skulltilleys" to race him. This was intended to be used in the game's demo as a joke explanation for why the race cannot be accessed.
This is of course a reference to The Legend of Zelda: Ocarina of Time, where Gold Skulltulas can be found all over Hyrule. Defeating them produces tokens, 100 of which are needed to lift the curse on a family in Kakariko Village which turned them into spiders.
The spelling "Skulltilleys" instead of "Skulltulas" appears to be an inside reference to the name of Rareware artist Carl Tilley, who worked on this game.

Super Mario Sunshine is surprisingly more realistic than later Mario games in one specific aspect: here, Mario will start drowning if he hangs on to a ledge in such a way that water is flowing into his nose and mouth, as one would in real life.

Observe Mario holding on to a ledge that water is flowing over in Super Mario Galaxy (left) and Super Mario Odyssey (right). If realistic physics applied, he should start drowning since his nostrils and mouth are covered by water flowing into them.
However, in these games the air depletion/drowning state is tied to the swimming animation. As long as Mario is not visibly swimming, he cannot be drowning even if he is covered by water.
In Super Mario Sunshine, however, air depletion is decoupled from swimming as an action, allowing Mario to realistically start drowning in this situation (note him flashing red and his air meter depleting).
However, he is saved by Sunshine's (also unique among 3D Mario platformers) ledge tiredness mechanic. After hanging on for 20 seconds, Mario will let go. This is also realistic, since why would he let himself drown?

The Switch version of Paper Mario: The Thousand-Year Door includes its own fictional language that is a cipher for English. Amusingly, the misspelled "Game Cuve" graffiti from the original version is translated into the new language... but still reads "Game Cuve" when deciphered.

The Nintendo Switch version of Paper Mario: The Thousand-Year Door contains an in-universe language used for signs and labels that is a cipher (i.e. a one-to-one symbol conversion) for English.
Textures that were in English or unreadable in the original (left) are translated into the cipher in the remake (right). The remake's poster reads "Wanted" and the signboard reads "Signboard".
A famously misspelled "Game Cuve" graffiti appears in Rogueport in the original.
In the remake, it can be seen through this arch from the back.
Analyzing it reveals that it is still misspelled! The designers deliberately kept the misspelling in the translation.
Here is the key to the cipher used.

Shigeru Miyamoto has claimed that Toad is his least favorite character in Mario Kart. Despite this, in all footage of him playing Mario Kart 8, he picked Toad every time. Whether he was joking or specifically picking a character he hates to challenge himself is unknown.

I have an important question. Nintendo has also just released Mariokart 7 for the 3DS. In every iteration of Mariokart, I've always preferred to play as Toad. Who's your favorite character?
That's the most challenging question! I'm sorry that I cannot come up with an interesting answer. Somehow, it's habit to me, but I play with Mario. He's a very balanced character.
Who's your least favorite character?
Toad. [Laughs]
My favorite character is your least favorite character?
I understand that he has some popularity. Somehow.
In a 2012 interview with Entertainment Weekly, Shigeru Miyamoto has claimed Toad is his least favorite Mario Kart character.
In December 2014, Shigeru Miyamoto and Bill Trinen played Mario Kart 8 against YouTuber Rosanna Pansino. Miyamoto picked Toad.
Also in December 2014, Shigeru Miyamoto and Bill Trinen played Mario Kart 8 against YouTuber iJustine. Miyamoto picked Toad again.
Finally, in January 2015, the two played Mario Kart 8 against YouTube group Smosh Games. Miyamoto picked Toad again.
Whether Miyamoto simply had an enormous change of heart about Toad in the intervening 2 years, or whether he was picking his least favorite to challenge or punish himself, is unknown.

Paper Mario: The Thousand-Year Door inadvertently depicts Peach as the quickest typist in the world. She is able to type up a 126-word email in exactly 3 seconds, making her 8 times faster than the current typing speed world record.

In Paper Mario: The Thousand-Year Door, Peach sends multiple emails to Mario during the plot. Almost all of them take her exactly 3 seconds to type.
The length of the emails she types in 3 seconds varies from 54 words to the longest one seen below, at 126 words.
Peach: I'm OK
My Dearest Mario, I send this letter in the hope that it reaches you safely. I am being held against my will in some strange place. Though I do not know where I am, I remain unharmed and in relative comfort.
Those who have captured me seem to be after the map I sent to you earlier. They may be hoping to use it to find objects they call the "Crystal Stars." I do not know what they are planning, but I have a feeling it is not anything positive.
Mario, please collect these Crystal Stars before they do. You must! They are already aware that you have the map, so please be very careful.
And please... Don't worry about me.
-Princess Peach-
At the current world record typing speed of 319 words per minute, Peach should have been able to get about this far into the email.
In order to finish the email in three seconds, she needed to type with an a speed of 2520 words per minute, 7.9 times the world record.
While the quick typing is clearly merely a way to make the scene move along more quickly and should not be taken as accurate depiction of Peach's typing skills, it is still humorous to imagine the implications arising from it if taken at face value.

In the prototype version of Mario & Luigi: Superstar Saga, Mario and Luigi would have needed to electrocute a living mouse for all eternity to solve a puzzle. This was changed in the finished version to a toy mouse, likely due to the original being absurdly cruel.

In the finished version of Mario & Luigi: Superstar Saga, there is a puzzle in the Woohoo Hooniversity basement whereby an electric circuit must be completed using mechanical toy mice as conductors:
Mario must fill himself with water, which Luigi shoots out with a hammer to push the mouse into the circuit, completing it:
After this, for the rest of the game, going back to that room shows the mouse continuing to be electrocuted as it is now permanently part of the circuit.
This is completely fine since the mouse is a toy.
However, in the prototype version of the game, the mice are clearly living animals, being shown to eat cheese when they stop moving:
Now, Mario and Luigi are completing an electric circuit by electrocuting a real animal.
This means that for the rest of the game, the circuit is completed via the mouse's body, meaning it is a real animal being electrocuted eternally.
The cruelty of this is so absurd that it was likely removed for this reason.

In Paper Mario, the Power Bounce badge's maximum number of bounces is arbitrarily capped against bosses, making Mario end the attack even with perfect inputs. Below are ways to determine if the player should feel bad about the missed input or if it was the game's fault.

$In Paper Mario, the Power Bounce badge's maximum number of hits is arbitrarily capped when fighting various enemies, particularly bosses. This means that even if you perform the input perfectly, Mario will'simply stop the attack all by himself at some point, making it look like it was your fault. Here is how to tell if your attack was capped by the game or if you missed an input: If you missed an input, the A button will remain on screen for a fraction of a second after the hit. In addition, Mario will jump off the enemy in a steep arc, landing close to the enemy. If you were capped, the A button will disappear on the frame Mario deals the final hit, and he will jump off in a larger arc, landing further away. If you see these signs, rest easy: it was not your fault. Source: YouTube user @Bonecrusher1022, youtube.com/watch?v=nLNyZyQxrr0$

Wrinkly Kong has always been wrinkly. However, for decades, her Donkey Kong Country 3 artwork was not available in a high enough resolution to see just how wrinkly she was. In 2025, Nintendo Music finally revealed it in a quality high enough to truly see the immense wrinkliness of her skin.

Cranky Kong's wife, Wrinkly Kong, was first introduced in Donkey Kong Country 2. True to her name, her skin was wrinkled, though not much more than Cranky Kong's.
In Donkey Kong Country 3, her skin texture was updated, but no artwork was published in high enough resolution to truly see the extent of her wrinkliness.
In January 2025, a Wrinkly Kong playlist was added to Nintendo Music. While the thumbnail for it is small when viewed in the app, extracting the source image shows it is in a higher resolution than any version of her Donkey Kong Country 3 artwork ever published. This allows the immense wrinkliness of her skin to finally be seen in detail. Every millimeter of her skin is covered with deep creases that resemble a topological map, or an undulating liquid surface.

It is possible to use a The Legend of Zelda cartridge to unlock the world selection option in Super Mario Bros., by swapping the cartridges without turning off the NES and performing specific actions in The Legend of Zelda before swapping back.

How to use The Legend of Zelda to unlock a world selection option in Super Mario Bros.
First, start up the Super Mario Bros. cartridge. This is necessary to set memory address 07FF to the value A5. TLOZ will not overwrite it, and SMB will need it to be A5 later.
Cartridge swap Super Mario Bros. to The Legend of Zelda. Do not turn off the power, instead just swap the cartridges and use Reset to make the console start the new game. TLOZ will be used to write a specific value to memory.
Start a new file and buy the blue candle.* You will need literally no other item, just the 60 rupees to buy it.
This is used to access the Level 8 dungeon. *Go right one screen, up two screens, and right six screens from the start to find the shop that sells it.
With the blue candle, open up Level 8**, and go to the room directly left of the entrance. This sets memory address 07FC to 20, which unlocks the level select in SMB.
**Go left one screen and down one screen from the blue candle shop and burn the conspicuous single tree.
Cartridge swap back to Super Mario Bros. Super Mario Bros. will look for A5 at 07FF, which it set itself earlier, and 20 at 07FC, which The Legend of Zelda just set, to unlock the level select.
Now, pressing B on the title screen will cycle through all worlds, allowing you to start the game on any of them, e.g. World 8-1. This would normally be accessed by beating the game, but this trick bypasses it.

Like Super Mario Bros. 2 before it, or Super Mario 3D Land and Super Mario Bros. Wonder after it, it simply does not have "points".
If the writer somehow meant something else the game does track, like coins or enemies defeated, this is a failure of communication as the game or its manual do not call them "points", nor do they function as a score in the way points do in other Mario games.
It is much more likely that the writer simply assumed that all Mario games have points, and did not check the specific game in question.

For fans of special challenges, the final Bowser battle in New Super Mario Bros. U presents the "Defeat Bowser By Throwing His Son At Him Challenge". Normally Bowser dies after 3 hits with the Clown Car. However, the player can also throw Bowser Jr. at Bowser NINETY times to win.

In the final battle of New Super Mario Bros. U, the intended method to damage Bowser is Bowser Jr.'s Junior Clown Car.
After knocking Bowser Jr. out of the Clown Car, Mario can ride it into the air above Bowser...
...and perform a spin down onto him. It takes three hits to defeat Bowser in this way.
However, if Mario stomps Bowser Jr. while he is running back to the Clown Car after being knocked out...
...he will retreat into his shell, which Mario can pick up.
Mario can then throw Bowser Jr. at Bowser...
...which does not even seem to do anything to Bowser except briefly redden the area of impact.
Yet, this does actually deal damage to Bowser... being 1.12% of his health. Bowser will die after being hit NINETY TIMES with Bowser Jr.'s shell, making this an extremely time-consuming way to win this battle.
...even more so than hitting him with fireballs, which takes 180 hits but at least does not have a cooldown like Bowser Jr. has.

In Wario Land 4, a single syllable of the Palm Tree Paradise vocals ("ni~") is stored in a higher quality than anything else in the files. In fact, it is stored at a quality too high for the GBA to even play back, making this completely inaudible on original hardware.

In Slipsand Galaxy in Super Mario Galaxy 2, there is an unexplained and out-of-place yellow flash during a Launch Star flight. This is because Mario actually flies through a fog area belonging to a planetoid from a different mission, and the very brief fog looks like a flash.

In World 8-7 of New Super Mario Bros. Wii, releasing a mushroom on the third Spine Coaster but not collecting it results in an entertaining interaction whereby the Spine Coaster will balance the mushroom on its nose, like a seal trained to balance a ball.

In Mario Kart: Double Dash, shadows in the environment do not follow any kind of lighting logic and appear to have been placed solely based on "vibe". This results in shadows being cast in nearly every possible direction at the same time.

In Paper Mario, Bowser claims that the Star Rod makes him invincible. However, in the first battle, it merely raises his Defense to a measly 1. If Mario is given just slightly better shoes, he can get through the protection. Bowser cannot handle taking over 10 damage, making the game crash.
