Sphynx Clip
Sphynx Clip is a speedrun strategy in the Sand Kingdom that allows the player to clip through the wall just behind the Sphynx at the backside of Tostarena Ruins. Clipping through this wall not only enables Mario to enter the treasure vault without talking to the Sphynx, but it also allows the player to access the room containing the Hidden Room in the Flowing Sands moon without the need to sink into the quicksand. Sphynx Clip can only be performed on game versions 1.1.0 and earlier.
This glitch was formerly used in the Any% category to save up to 10 seconds. However, since version 1.3.0 has significantly faster loading times than all previous versions of the game, the time saved by Sphynx Clip and other version-exclusive tricks has been negated.
