He couldn't move very quickly, but neither could any of the others, so closely packed were they in the tiny opening.
He noted a tiny grilled opening in it, like that of a cell.
That tiny opening turned out to be just enough for desperation to squeeze through.

He managed to insert one of the fingers into a tiny opening.
With steady force against the tiny opening, he pushed forward.
He watched the tiny opening seem to suck at her finger.
They did not break, but parted, and a tiny opening appeared.
