In 2017, the U.S. government used a cover of music from Yoshi's Island DS on one of their websites, presumably without permission, as the music was removed immediately after this was publicly discovered.

In the character selection screen of Mario Kart Wii, the princesses have tiny biker versions of themselves hidden inside their bodies. This is due to the game loading both the dress and biker models at the same time for efficiency, and simply shrinking the currently unused one.

Super Smash Bros. contains a sneaky "delayed action" anti-piracy measure to lull the illegitimate user into a false sense of security. The game will be normal the first 68 times it is launched. Starting with the 69th time, however, every selected character will turn into Mario.

Experimental Post: Wiggler Wednesday I have compiled a collection of obscure facts about Wiggler in Super Mario 64.

In Mario Kart World, NPCs will park their cars, exit them, and walk around. However, the game does not actually keep track who each car belongs to. As such, a different NPC than the owner may drive away with a car, seemingly stealing it.

Development files for Yoshi's Island reveal that Yoshi was originally meant to have a human voice. Lines for transforming into his various forms, including unused ones like Tree Yoshi, have been found.

In Donkey Kong Bananza, if Pauline sings for long enough on the Resort Layer, an underground beach, birds gather. However, no birds gather on DK Island, even though parrots can be seen flying around. It appears that the birds on DK Island simply do not enjoy Pauline's singing.

Zooming in extremely closely onto the Super Mario Galaxy Movie logo shows a planetoid with waterfalls next to a planetoid with a single large tree. This may be the movie's representation of Honeyhive Galaxy from Super Mario Galaxy.

The DOS version of Mario is Missing does not have voice acting in the ending. However, unused voice lines meant for it exist in the files. Below is a recreation of the cutscene with the voices edited in.

Mario characters' cartoony eyes require their eye movements to be animated by sliding around the iris instead of rotating the eyeball. Despite this, some Switch games fully model their eyeballs even though it not being necessary, revealing they take up a startlingly large space inside their heads.

In Paper Mario: Sticker Star, it is possible for Kersti to kill Mario just for talking to her. At the end of World 5-3, talking to Kersti on a specific frame will make the raft disembarking cutscene not play. Instead, Mario will fall into the water and die.

In Super Mario Odyssey, kicking things is Mario's highest priority, overriding all other actions. If a kickable object, such as a football, is thrown at Mario while he is asleep, he will momentarily wake up just to kick it before instantly going back to sleep.

This in-store display for a 2019 line of official Mario clothing is possibly the most inaccurate Super Mario Bros. artwork ever used in an official capacity. Nearly every element of the image is either wrongly sized, misaligned, or placed in a nonsensical manner.

In Donkey Kong Bananza, all of DK's Bananza ability sound effects harmonize with *all* background music. While only the dedicated Bananza songs normally play during this, turning off "Bananza Vocals" in the menu reveals that they harmonize with every piece of music in the game.

In both versions of Super Mario RPG, Mario receives rewards for staying at the luxury Marrymore Hotel suite, but the rewards seemingly stop after 15 stays. However, there is one final hidden reward, given out after staying an absurd *200 nights* at the suite: 20 Frog Coins.

In Luigi's Mansion, there are decorative leaking pipes on the ceiling of the Pipe Room. If Luigi shoots ice at them, they will stop leaking, presumably due to the water inside freezing over. There is no purpose to this interaction other than maximum realism.

The intro to Game & Wario shows a world map on Wario's wall. While roughly corresponding to the map of our world, it shows some differences in the shapes of the landmasses. Most concerningly, it appears that in Wario's world, Europe does not exist.

In Super Paper Mario, a wall in Chapter 1-4 that appears to be covered in random decorative patterns is actually filled with deep lore, connecting the iconography of all four Sages of the Tribe of Ancients together.

In Super Mario 64, the haunted chairs and normal chairs are actually the exact same object, whose behavior is determined solely by how close it is to the piano. Chairs close to the piano get it assigned as a parent object. Only parentless chairs are coded to become haunted.

In Super Mario World, the Big Bubble enemies are just minimally edited and recolored bodies of Big Boos. While this is most likely simply a case of asset reuse, it can also be interpreted as Big Bubbles being a more immaterial, protoplasmic state of Big Boos.

In Donkey Kong Bananza, Pauline's idle animations evolve over the course of the game as she learns to be more comfortable around DK. In the beginning, she looks around worriedly. After Sublayer 300, she starts ruffling his hair, and after Sublayer 1400, starts tickling him.

Due to a bizarre interaction between Pokeys and Turn Blocks in Super Mario Maker 2, it is possible to create a "Jumpscare Pokey" that rises up extremely quickly and unexpectedly from the bottom of the screen.

In Super Mario Odyssey, if Mario touches Glydon after he lands from defeating a Yoofoe miniboss, he will gain a brief burst of hyperspeed, making him zoom around the arena excitedly after the victory.

An obscure Super Mario Sunshine worldbuilding detail seen in extremely blurry writing on the map screen is that parts of Delfino Plaza are called "Mouth Bay" and "Nose Beach". This is due to Isle Delfino's dolphin shape, whereby the bay is at its mouth and the beach at its nose.

In Donkey Kong Bananza, DK follows objects of interest with his eyes. However, he has an incredibly short attention span. Whenever a new object enters his vision, his attention is drawn to it instead. If many objects are moving, he will be distracted by each new one.

In Super Mario 64, there is a 1/256 chance of a fish spawning when Mario jumps out of water anywhere. However, during development, the fish were instead restricted to a single spot in Whomp's Fortress, which spawned them continuously in the form of a bountiful fountain of fish.

A glitch in Mario & Luigi: Brothership allows Mario and Luigi to fish anywhere. As fishing is internally of a higher priority than walking, Mario and Luigi will not get up from their sitting poses, and instead glide around while sitting just so that they can continue fishing.

A player looking for the most balanced build in Mario Kart World may find that the game claims Koopa Troopa on the Billdozer is "perfectly balanced", but this is a lie. The game simplifies the real stats for display. The actual most balanced build is Bowser on the Tune Thumper.

Mario Party: The Top 100 contains the unexpectedly profound test message "It's only after we've lost everything that we're free to do anything." This is actually a quote from the 1999 film Fight Club.

In Super Mario Bros. Wonder, some enemies enter "sulk mode" when they are surrounded by blocks and cannot move, whereby they will sit down and look upset with their situation. Some enemies can sulk but never do so during regular gameplay. Below are all enemies capable of sulking.

The demo version of Mario Kart: Double Dash contains an unused Game Over screen. Notably, the smoke graphics used here are humorously called "smork" internally. It is unknown if this is a legitimate misspelling of "smoke" or if the word was deliberately spelled in a funny way.

Super Mario Odyssey loads areas faster in handheld mode than when the Nintendo Switch is docked, though only after beating the game on that save file. Before completing the story, there is no appreciable difference between the loading times.

Due to a bizarre code interdepency in Super Mario Sunshine, Mario can gain permanent aggression to durians. While normally, he can handle them gently, if Mario enters a sewer and jumps once, he will become incapable of kicking them with anything except full force.

Internal variables in the Super Mario Galaxy games refer to Spring Mario as "Rabbit". This suggests the form, with its constant hopping and high jumps, could have been originally intended to be rabbit-themed. In addition, speculation on this being related to Star Bunnies is provided.

A 1991 official Japanese Mario encyclopedia suggests that Lava Bubbles are a "manifestation of the resentment of the Koopa Troop for being defeated by Mario".

An unused object found in Yoshi's Island is the "Overly Congratulative Green Coin". It is identical in functionality to a red coin, but plays the Perfect Clear fanfare when placed in specific areas. This causes the game to appear to unnecessarily celebrate every single coin.

In Mario Kart World, an MKTV helicopter tracks the racer in first place on routes between tracks. Despite appearing to only be a decorative element to provide the feeling of a real rally, it actually has collision and can block projectiles aimed at first place.

In Donkey Kong Bananza, Fractones can be modified by throwing chunks of dirt at them. With enough patience, so much material can be heaped on them that they reach their maximum size, a giant cube. After the cube form has been attained, no further material will adhere to them.

Due to the imprecise manufacturing methods used to produce officially licensed 1989 Princess Peach cake toppers, a majority of the figurines suffer from eye misalignment in various degrees of severity.

In Super Paper Mario, Tippi claims the Hedron obstacles in Chapter 4-3 are indestructible. However, there is an Easter egg whereby shooting them 256 times (regardless of Mario's actual attack stat) destroys them and awards 256 points.

In Super Mario Bros., the first vertical lift platform in World 6-3 does not have a fixed range like it may seem at first. Instead, it slowly keeps increasing its range, so that keeping Mario on the platform will eventually result in his death.

Mario & Luigi: Superstar Saga contains an unused animation for Mario and Luigi after eating a Mushroom in battle whereby they would have assumed a whimsical delighted pose to show how much they enjoyed it, as though breaking out in song.

In Donkey Kong Bananza, you may have noticed Donkey Kong looking more orange than usual sometimes. This is due to his fur becoming slightly brighter when he is full on Bananergy. In practice, the game's dynamic lighting makes this very difficult to tell unless comparing in identical conditions.

In Super Mario 64 DS, by alternating pressing Y+Up/Down/nothing/Down/nothing every 5 frames, Mario can vibrate up every slope in the game.

In NES games, Luigi is at an unfair disadvantage since he cannot pause the game. While this might be self-evident to Japanese players, international players might find this handicap baffling. The reason is the Famicom's lack of Start and Select buttons on the second controller.

In Mario Kart World, the whole world is seen in a low-detail, but mostly accurate version from Rainbow Road. However, one location fell victim to the terrain simplification: Great ? Block Ruins has been flattened like a pancake.

In Donkey Kong Bananza, Pauline will often point out a banana when Donkey Kong approaches it. Due to a quirk in the game's item noticing priority, it is possible for Pauline to shout "An apple!" when approaching a banana, appearing confused about the nature of the fruit.
