There are three different versions of the Japanese Donkey Kong arcade motherboard. On one of them, a glitch exists that makes it possible to skip the entirety of the 25m stage simply by performing a precise jump from the second platform, as shown in the footage.
Note how Mario actually wraps around from the bottom to the top of the screen (Mario’s head is on the bottom edge while his body is coming out of the top edge of the screen). Him being in the upper part of the screen is counted by the game as having reached the platform Pauline is on, causing Donkey Kong to abscond and the level to be declared completed.

Official Donkey Kong Jungle Beat wallpaper available from the game’s Japanese website in 2004. Interestingly, it uses a Japan-only tagline for the game, “THE KING OF KINGS! DONKEY KONG IS HERE!”
It is theorized that a possible reason this tagline was not used outside of Japan is that “King of Kings” is a title used in the Bible to refer to Jesus Christ (e.g. Revelation 17:14).

At launch, Mario Kart World contained a glitch whereby taking one of the ramps on Mario Circuit and using a Feather on the top of the jump caused the racer to enter a glitched low-gravity state where the vehicle would descend extremely slowly, taking up to several minutes to actually land.
This glitch was patched in one of the game’s first updates.

For performance reasons, the Waluigi Stadium track in Mario Kart: Double Dash becomes emptier in split-screen mode, with the animated arrow signs disappearing and the amount of audience members in the stands being reduced.
This creates a paradoxical effect whereby the audience seems to be inversely proportional to the number of actual racers, as though solo time trial races are more interesting to the audience in-universe than races with multiple participants.

Strangely, the motor scooter in Super Mario Odyssey is affected by personalized gravity that does not always point straight down as expected, but rather changes based on the inclination of the slope it was last standing on.
For most slopes that can normally be reached with the scooter, the gravity changes so marginally that it is difficult to notice, but getting to the tops of the towers in the Mushroom Kingdom allows it to stand at an angle that actually makes the effect very pronounced, as seen in the footage.

In Super Paper Mario, the River Twygz Bed track is infamous for being highly unsettling and featuring distorted voices.
When putting the track through a voice isolation algorithm, they can be heard marginally more clearly. It is theorized that the voices are real recordings of dialogue, potentially in Japanese, though any actual sentences (if any are being said) still elude being deciphered.
