Batman Arkham Asylum Killer Croc's Lair Chapter 11

Scarecrow dangles his toxins over the river in the pipeline, threatening to drop them in if Batman comes closer, which would affect the entire city of Gotham. As Scarecrow stands on the edge, Croc jumps out of the water and grabs him. Croc is about to eat Scarecrow, but Batman hits his shock collar with a Batarang, forcing him to recoil and drag Scarecrow into the water with him. Batman ventures into the sewers and, while frequently being attacked and pursued by Croc, whom he fends off by constantly activating his shock collar with batarangs, gathers all of the required spores. As he prepares to exit the lair, Croc suddenly charges at him through a tunnel, but Batman destroys a weak part of the floor using his Explosive Gel, just as Croc runs over it, sending him plummeting down into the river below.
