Wrecker Phantom Skip
Warp Phantom Skip
By blowing Zelda over the sand it gives enough time to equip the sand rod and save her from sinking. From there simply grab the arrow pod and resume the puzzle as normal.
This trick allows you to skip grabbing the warp phantom after completing the wrecker part of the room. Along with Wrecker Phantom Skip you can complete the entire floor 26 with just the torch phantom, saving more then a minute.
