The Batman feels Croc's claws scraping down his sides, and it doesn't exactly hurt, not in the moment, but he can feel his pulse start hammering. Panic. Not good. And they're moving back fast, he has only a second to think before they hit the water.

Batman takes a deep breath, holds it, and then his entire world is submerged in muddy water. He can hardly see, he can't breathe, and Croc's claws are still piercing him. If he tries wriggling out of Croc's tight grip he'll get sliced up more, so Batman lets go off Croc's vest, and begins to claw at Croc's face.
