Rock has a foul mouth and even fouler disposition, He is hot-tempered and prone to snapping at any who invoke his wrath, Straightforward and filled with candid responses, Rock says things as they are and is not afraid of coming off as rude or impolite, He is also a heavy smoker as well as an alcoholic, There are often cigarette butts and a bottle of beer on his coffee table, He prefers to stay more as a penguin rather than his humanoid form.
