It is possible to get out of the sand with nothing. Press against the wall, hold down, crouch jump while continuing to hold down, then down-grab immediately by rolling from down to diagonal down-forward.

Before crouching, either wait to get i-frames from a Zoa hit, or kill the Zoas and leave their drops uncollected somewhere out of the way.

Requires:

"canEscapeSand"

Dev note: This strat is unimportant logically, since there are easier ways to cross the room, but in practice it is useful, so it is good for it to be documented here.
