Super Mario 64 has a number of impossible coins – that is, coins that are impossible to collect. Well, it looks like the mystery around one of them has been solved 20 years after the groundbreaking platformer came out.
YouTube channel UncommentatedPannen documents an impossible coin found in the huge version of Tiny-Huge Island. In one section of the level, there is a line of four coins. So what? Well, everywhere else in the game, coins line up horizontally in fives.
So what happened to the fifth coin in this particular line? UncommentatedPannen explains that the fifth coin immediately despawns after Mario comes close enough to spawn it because the spawn marker is positioned too far below the slope.
