These Great Auks have brown backs, white bellies and white spots on their eyes. They have grayish-black beaks. They only wear green-red striped-Scottish kilts. They don't appear to have any weapons.
When close, they swing their beaks forward, when near, they slide on their bellies at you, when far or unreachable, they, like the puffins, gargle up a ball of fish and throw it at you, although this version of it is more erratic.
