Waddle,Penguins!
A Penguin's incubation period lasts for 2-3 months. Think of all of the time Mumbai was in his egg during "Happy Feet". The Penguins average weight is just about 10 lbs. The temperature in their natural habitat (Antarctica) is a frigid 40 degrees Fahrenheit. Never keep penguins in your apartment like Mr.Popper did from "Mr.Popper's Penguins", it's too warm for them, most likely. A penguin's lifespan is 15-20 years long.
