He is a rockhopper penguin who lives on Iceberg Island. 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. Rock is furthermore very fond of his "decorative feathers," and will get angry should they be identified as eyebrows.
