In the beginning of Mario & Luigi: Superstar Saga, Peach is cursed to have her voice turn into bombs whenever she speaks*. The bombs cause explosions and shake the ground upon falling.

The prototype version of the game also adds Toads falling from the ceiling when Peach’s voice bombs explode, which was removed from the finished version of the game.

*this situation is more complex than it appears at that point in the game, but a more detailed explanation of the events is omitted to reduce spoilers for those who have not yet played it.

A prototype for Yoshi’s Island contained an early version of the game’s intro stage theme (playing in the small tutorial section between the intro cutscene and entering the world map for the first time) that is, surprisingly, more complex than the finished version.

While the finished version of this theme consists of a short loop, this early version has an actual melody on top of the loop that is removed in the final game.

Super Mario Galaxy contains four unused objects that each have a “cut plane”, a dividing plane in their models along which they are meant to be cut, as though sliced with a blade. It is unknown what these could have been used for.

As internal files for Super Mario Odyssey contain evidence of a scrapped “sword attack” for Mario, it is possible to speculate that a similar ability was at one point planned for Super Mario Galaxy as well (alongside with early Super Mario RPG designs using a sword but not implementing it in the final game, Mario games seem to have a history of proposing but ultimately forgoing the idea of giving Mario a sword).

New Super Mario Bros. U/Deluxe contains a “Phantom Piranha Plant” phenomenon whereby sometimes Stalking Piranha Plants will simply disappear without any explanation.

Note how in the footage, Toadette is on a platform with a Piranha Plant in the beginning, then very briefly lets it out of sight when picking up a Koopa shell. However, upon returning, the Piranha Plant is gone. Note also that these enemies are programmed to turn around on ledges, so it cannot have walked off the platform.

In the Super Mario Bros. 3 style of Super Mario Maker 2, if Mario enters a Twister while obtaining a Fire Flower and shooting a fireball immediately afterward, he will become stuck in his falling animation until he leaves the room. Note how Mario slides around without changing his sprite after touching the Twister.

In Luigi’s Mansion 3, there is a genie lamp hidden in the sand in the Sandy Grand Hall room on the Tomb Suites floor. The lamp has a unique property where its buoyancy and gravity values result in it becoming stuck in mid-air as long as Luigi is blowing air at it, as seen in the footage.

In Super Mario Galaxy 2, Slimy Spring Galaxy is memorable for its environment, whereby Mario starts off in the depths of a misty cave and finally emerges onto a cliff overlooking a plain at sunset.

Interestingly, the sunset skybox is actually always loaded, but is completely covered up by the fog effect in all areas inside the cave. At the beginning of the galaxy, if Mario looks back towards the point where he came flying in from, only a part of the cave is visible, dissolving into fog in the distance.

Removing the fog shows that this is actually an opening leading outside, through which the sunset could be seen if the fog wasn’t in the way.
