Mr. Popper's Penguins is a children's book written by Richard and Florence Atwater, with illustrations by Robert Lawson, originally published in 1938.
It tells the story of a poor house painter named Mr. Popper and his family, who live in the small town of Stillwater in the 1930s. The Poppers unexpectedly come into possession of a penguin, Captain Cook.
The Poppers then receive a female penguin from the zoo, who mates with Captain Cook to have 10 baby penguins. Before long, something must be done lest the penguins eat the Poppers out of house and home.
