Small Mario Findings

Unused image found in the system files of the Nintendo Switch, being a slightly smudged jumping Small Mario sprite from Super Mario Bros. with "fixme" written underneath it.

Based on the filename (NewsIcon_Nintendo) it was likely meant as a placeholder for something related to the news option on the main menu screen.

In the "Sled to the Edge" minigame in Super Mario Party Jamboree, the aim is to let go of the Cooligan enemy pulling the player's sled in such a way that it stops the closest to the edge of the ice without going over.

If the player manages to stop the sled at precisely the edge, the character will count as winning, locking into place and assuming a celebratory pose (as seen with Mario in the footage), while the sled itself actually decouples from the character and ends up going over the edge by itself.

The model of the Koopalings used in World 6-Castle and World Star-Castle in New Super Mario Bros. 2 is extremely highly optimized. While the Koopalings do turn within a specific angle as they fly around in the background, they do not turn fully sideways or all the way around.

This allows the programmers to determine which polygons of their model will never be visible from the angles they can be displayed at, and remove those polygons from their models. This results in most of their backs being missing, as seen in this turnaround.

In Super Mario 3D World, characters other than Mario have other, non-orange color schemes in their cat forms (left). However, in their Lucky Cat statue forms, they all become golden (middle).

It may not be obvious due to the gold filter, but during this transformation, all characters actually assume Mario's orange cat coloration, instead of having the filter apply to their existing colors (filterless look at the Lucky Cat form on the right). It is unknown why this happens, though possibly to equalize the golden appearance across all characters, as having a golden filter applied to five different colors would result in five different shades of gold.

According to the official Japanese guide for Princess Peach: Showtime, the horses ridden by the enemies in the Wild West plays are humorously called バッドネスホース, which is a transliteration of the English phrase "Badness Horse" into Japanese.

Most of the game's enemies have names with actual Japanese words in them in Japanese, with the few others that are also transliterated English being regular phrases ("Laser Patrol", "Little Snake"), making "Badness Horse" unique in its unusual usage of the word "badness".

In Super Mario Galaxy, if Mario spins near a shell to pick it up underwater and is hit at the same time (as e.g. by the Urchin in the footage), the shell will remain suspended motionlessly in that spot for a few seconds before exploding.

In Donkey Kong 64, standing on a Lanky Pad as Lanky Kong (with the Baboon Balloon ability unlocked) and pressing Z will cause him to inflate himself like a balloon and start floating upwards.

However, if this is interrupted by being flattened by a Kosha enemy's club, Lanky will still continue rising for a brief period even though his animation will be overridden by the one of him trying to straighten himself out after being hit.

This results in the humorous impression of Lanky flying into the air through the sheer power of flapping his arms, like wings.

In Super Mario 64, Peach's Castle stone textures have a curious colorful noise pattern overlaid over them (original textures on the left, enhanced contrast on the right) that is not present in any other textures in the game.

Theories regarding this range from artifacts of a specific type of compression only used for these textures, to this being done deliberately to subtly make the grey textures more visually interesting.
