Penguin dads are very special because they help take care of the eggs. When the mother penguin goes swimming to catch fish for the family, the dad stays behind to keep the egg warm. He gently holds the egg on top of his feet and covers it with his feathers. This way, the egg stays nice and warm, even though it is very cold outside! The dad keeps the egg safe and cozy until it hatches, and then the baby penguin can come out and stay warm with its parents.
