I like that part too. I also like how when they get tired from walking, they just go on their bellies and move with their fins. It was so cute.
I started to like penguins a lot when I saw the Happy Feet movie. It was so sweet.
I also find it interesting that the father penguin takes care of the baby in the cold, starves for months, while the mother goes and gets food. I also found it very cool that the father has a reserve food in his mouth and feeds this one drop to the baby penguin and it lasts for a day when the mother doesn't return to them in time.
I found it sad to see lil baby penguins dead and the mother sad.
There were so many other interesting things that I like about penguins and I could go on and on....
