The Koopa Bros. from Paper Mario are a clear reference to the Teenage Mutant Ninja Turtles, however, in most versions it is limited to their visual design. The German version takes it further and gives them names that parody the TMNT: Citronello, Melanzano, Pomodoro and Asparago.

Mario Party 2 contains a debug animation test for player models, including various costumes. All of them mostly work correctly, except for Cowboy Luigi, who seems corrupted. Every time Cowboy Luigi is loaded, there is a chance that his model will be completely scrambled.
56
In Paper Mario: The Origami King, characters have back sprites for all animations, including ones that would never be seen from the back during regular gameplay. One of Bowser Jr.'s unseen back sprites has one of his legs detached from his body, floating in midair high above him.

There is a single Star Bit in Super Mario Galaxy that spawns only when the game is not played in widescreen.
58
In Donkey Kong Country 2, a Klobber enemy that is dropped into lava does not actually die. Instead, it is teleported so far up that it takes 3 minutes for it to fall down. If the player waits in that spot for 3 minutes, the Klobber will fall down from the sky.

In Super Mario World, the variable that determines which way Mario is facing has two values that are used - left and right - and 254 unused values. Making Mario face these "extradimensional directions" can distort him, discolor him, or even turn him into eggs.

As pointed out by reader @ChiefNeif, the gun is used as a reflection texture for the golf club, being so stretched out that it is not recognizable in-game. However, it is still unclear where the gun image comes from or why it was chosen for this purpose. twitter.com/ChiefNeif/stat…

Plum is a golfer from the N64 Mario Golf whose trophy appears in Super Smash Bros. Melee. For an unknown reason, whenever Plum's trophy is displayed, this pixel art of a gun is loaded into the game's memory. It only appears here and is not used by the game in any other context.

In Mario Kart Wii, Wario's Gold Mine contains a texture that appears to be completely blank. Concealed within is a Mii head that may or may not be faceless. An analysis and mockups of what the Mii may have looked like are provided.
64
A debug build of Wario Land 4 was found that allows the player to deform Wario's sprite in the intro cutscene with button inputs. Interestingly, if Wario is made too wide, the cutscene will never end, with Wide Wario simply jogging in place forever.
65
In Mario Kart: Super Circuit, the Grand Prix rank is calculated with a complex formula that awards points for player performance. However, the formula also gives free bonus points simply for playing as certain characters, with Bowser getting the most and Yoshi getting none.
66
Paper Mario: The Thousand-Year Door contains an early graphic for the rock thrown by the audience, where it was a brick instead. This was likely changed due to the brick being more realistic than a cartoon rock, appearing more violent. Below is the brick reinserted into the game.

A widespread problem with GBA ports was that the system had no backlight, resulting in dark areas needing to be brightened. The Donkey Kong Country 3 GBA prototype overcompensated for this on the Floodlit Fish level, causing the glowing fish to be blindingly bright.
68
In Super Paper Mario, it is possible for Mario to become trapped in a claustrophobic situation, squished by the ceiling in a room barely larger than himself and unable to use the door to get out. Details in image.
69
According to review aggregator site Metacritic, Donkey Kong: Barrel Blast is the worst game in the greater Mario franchise, being the only game out of all of its subfranchises to have a score lower than 50 and "generally unfavorable reviews".

In Yoshi's New Island, instead of having separate models or animations for facing right and left, the Gusty enemies simply have a face on both sides of their heads, resulting in a two-faced creature.
71
In Wario Land 4, the owner of the Item Shop offers Wario a smile for free. This is actually a reference to the menu of McDonald's Japan, where a smile is something one can order for 0 yen.
72
In Paper Mario: The Origami King, there is a room where Professor Toad tells Mario "Don't leave without me!" Contrary to expectations, using glitches to do that does not result in Professor Toad being absent - instead, the game overcompensates and spawns two Professor Toads.

Super Princess Peach contains several test rooms in its files. One of them is the "Iggy gives Peach money" room, which consists of a cutscene of Iggy Koopa spawning some coins and Peach collecting them. Note that Iggy appears only in this room and not during actual gameplay.
