Position the snail on the high pixel without using x-ray. Ceiling clip then use the stored spark while in the crouched pose that Samus is already in to spark vertically and clip through the next block. Changing pose will make it so Samus is no longer able to spark.

If Samus has a blue suit, after standing up on the snail, crouch to gain a shinecharge, then press forward to stand again; continuing to hold forward while jumping allows Samus to clip through without activating the spark.
