Only allowed in Any% runs, this trick is not required to submit Any% runs though, you can just play the game as normal to get to the hallway if you wish. This is just a big timesave, only necessary if you are aiming for a top 3 time.

If running Any%, you must be running Old Patch, see https://www.speedrun.com/poppy_playtime/guide/37l3t for download.
