Frisk's screams ring in the Batman's ears. He can only catch glimpses of them scrambling backwards in the mud, as he wrestles with Killer Croc. Even with his arms around Croc's throat, there's no way Frisk can make it to safety at that speed. Batman's shriek stops.

"Get up!" He screams. "Run!"

He needs to buy them more time; Batman shimmies forward, keeping the choking grip on Croc's neck, and sinks his teeth into Croc's face, sharp little fangs scraping the nubs around Croc's eye.
