Chuuls are excellent swimmers but prefer to attack land-bound creatures or those wallowing in shallow water. Once they seize their victims, chuuls often drag grappled foes back into deep water to drown them. Lizardfolk are by far the chuul's favorite prey, though those pale chuul breeds that live underground prefer morlocks, duergar, unwary drow, and other unfortunates who get too close to their subterranean waterways-with the exception of troglodytes, whose flavor chuuls find particularly offensive.
