If you have at least 6 soul going into this room you can do a fireball stall over the water. This on its own should be faster (the exact timesave depends on the movement prior in the room, but it should be the same as the All Skills dash slash which they do every time) This loses about 0.1s to normal movement if you turnaround fireball and about 0.25s if you fireball forward, but if you fireball forward you can also kill one or both of the enemies and collect their geo. Especially useful if you're doing pacifist mantis pogo since you're usually down around 10 geo compared to other strats.
This was found by JaGOAT (as many cool strats are), but I'm posting on his behalf since he isn't really active here.
