Soon a tiny opening appeared, no bigger than a small stone.

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.

It had been moved from across the mouse hole leaving a tiny opening clear on the left side.

It was a tiny opening anyway, and hard to feel with the fingers.

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.
