The Penguin Crane is the boss in Sexy Parodius stage 4A.

The only time you can hit the penguin is when he is on the far right side of the screen or at the top. Once in a while he will drop out boxes, shoot them for women or birds that leave power-ups behind. When the penguin's machine is at the very top of the screen, make sure you are near the bottom to block his projectiles, same when he is moving up and down on the right side of the screen. After you defeat him, he will pull out a machine gun. Just stay away until he disappears.
