In Luigi’s Mansion, the Tea Room contains gravity-swapping panels that are used to first get Luigi onto the ceiling and then down from the ceiling onto a table, to bypass his inability to jump in that game.
However, an extremely rare glitch may occur when using the tile to get down onto the table, whereby Luigi will go up instead of down, clipping through the ceiling of the room onto the Balcony, where the area’s boss, Boolossus, is fought.
If Luigi has the Ice Element Medal at the time the glitch occurs, Boolossus can be beaten and this can be used to skip part of Area 3. If he does not, the battle is unbeatable.

Mario Tennis for Game Boy Color contains a debug room in its files with characters that each perform a test function upon interacted with, such as sending the player to a specific point in the game, starting a tennis match, etc.
However, there is one character that is a green cat that merely says “You two are good. I’ll admit that… But remember this.” when talked to, and does not have any other function. It is unknown if this is merely included to test dialogue, or whether the cat had some function at an earlier point in development that was removed.

Super Mario 64 contains a mysterious “WALL” counter with an unknown purpose. On every frame the game is running, a function sets “WALL” to be equal to 0. There is no other code that either changes the value to anything other than 0, or reads it for the purposes of doing anything with the information.
As such, this variable is continuously updated to be the same value, 30 times a second, forever, while affecting literally nothing.

The original SNES version of Super Mario RPG contains a debug item called “Doom Bomb” that deals 255 damage to a party member, killing them instantly.
It is notable that rather than simply using a debug menu that would allow HP of party members to be set directly, killing them for testing purposes was implemented in this whimsical in-game way, even giving the item its own unique name.
