Small Mario Findings

Top: in Mario's Game Gallery for PC, the name of the game is visible in the background behind Mario, repeated across the screen.

Bottom: however, on the back of the game's box, an early screenshot of the Dominoes game shows that the name of the game seemingly was originally supposed to be "An Evening With MARIO™" instead.

Top: in WarioWare: Get It Together, the Supreme Developer is a character that appears at the end of the main part of the story and resembles Wario with a long flowing beard.

Bottom: interestingly, the beard is actually a separate graphic and the Supreme Developer's chin is fully drawn underneath it, which can not be seen in-game and requires extracting the graphic to view. This makes him appear even more like Wario.

In Super Paper Mario, enemies are programmed to not give out points if they are defeated by a "non-player source" (any damage not originating from a player character or an item used by the player). While this makes sense in order to not award the player points if the enemy manages to defeat itself with its own attacks, this for some reason also applies to bosses.

As a result, some bosses can actually end up not giving points for being defeated if the last hit to the boss is dealt by an enemy source. In the footage, Francis is defeated by a Meowbomb explosion and gives no points (note the lack of a point display appearing when he is hit).

While this is helpful if the aim is specifically to collect as few points as possible as part of a self-imposed challenge, this may be frustrating if it happens to a player by accident during regular play.

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".
