These penguins live in holes in the ground, often underneath grassy bushes. Several hundred more are in the mine field. There you will see a crouched penguin staring at you curiously. For these penguins to ambulate from the beach upward to these holes requires that they do some rock climbing. Please now refer back to the previous portion describing the lack of knees.
Penguins are too short and too round to climb anything more steep than a handicap ramp.
