Mugsy

Rocky and Mugsy are a pair of gangsters that appear in the shorts. Rocky, the leader and brains of the two, is the short one with the black hair, a hat that covers his eyes, and is constantly seen smoking a cigarette, and Mugsy, Rocky's henchman, is a big stupid oaf.

Rocky was first created in 1946 because many of Bugs Bunny's past foes (such as Beaky Buzzard, Elmer Fudd and Yosemite Sam) were considered very stupid, and that Friz Freleng needed a more intelligent (and challenging) figure to face the rabbit.
