WHAT COLOR?

An extremely minor and easily overlooked detail in Super Mario 64 is that one of the four pillars in Shifting Sand Land actually has a different texture from the other three, being more visibly covered in sand. This is the pillar that is located in the quicksand near the Tox Box maze; it is also the only pillar that is lower than the other three, presumably due to having sunken into the quicksand.

While this may at first appear to be an oversight, it must be deliberate since the texture used for that pillar is unique and not used by any other object in the level. It seems that it was supposed to indicate that this pillar is less well-maintained than the others, with it being sunken into the quicksand, but the difference between the textures is so subtle that very few players would actually notice it during gameplay.

The low-quality models of racers that are displayed when they are far away from the camera in Mario Kart Tour are created through an automated process instead of being manually optimized as they are in some other Mario games. This results in many oddities in these models that are only visible if they are examined in a model viewer, as they would not be seen up-close in the game itself.

Iggy's low-quality model simplifies the lenses of his glasses to a quadrilateral shape, however, instead of making it a rectangle to convey a neutral expression, the lenses make him look distinctly angry instead.

Super Mario World concept art only ever shown once, extremely briefly, during a montage in the September 2025 Nintendo Direct, while the camera was panning across it. Here is the artwork stitched together from all frames showing it, at the highest resolution available from the video.

In Super Mario 64, changing areas between the overworld and a course does not restore Mario's health, so it is possible in many cases to cause Mario to go to a different area with 0 health, resulting in him dying immediately after arriving. This is most commonly seen when selecting the "exit course" option with precise timing after taking mortal fall damage.

A rare variant of this occurs with the Big Boo's Haunt entrance. If Mario defeats the Boo in the courtyard that contains the cage leading to the course, and then reduces his health so that a Boo approaching from behind deals the last hit to him and also pushes him towards the activation area of the cage, he will enter Big Boo's Haunt with 0 health. This will make him die immediately, as seen in the footage.
