March of the penguins

1.They have to over come hunger and the super cold weather

2.it's cold so they have to form a huge mas to move when it's winter.

3.They need blubber to stand the cold and flippers to be able to swim away from predators.

4.There is no light sometimes because of the earths orbit around the sun and when there is no light there is colder weather so it makes it harder for the penguins to move by them selves,they need to stay huddled.
