A snake stuck its head out over the Gorgon's veil and hissed.

Sheila was sucking in her breath, it reminded him of the way that snake had hissed.

The snake that was wrapped around her shoulders awoke suddenly, tensed, and hissed.

The snake hissed, flicking out a tongue that was like a black whip.

"We can take it to Salmissra now," the snake hissed.

His chest heaved for air, and the snakes hissed.

The snakes lifted their heads and hissed in unison.

The snake hissed at me when I got near it.

The snake hissed and tried to get out.

The snake around it uncoiled and hissed at the king.
