Mr. Popper dreams of being an antarctic explorer and living among the penguins alongside his hero, Admiral Drake. But as a house painter with a family to care for, Mr. Popper knows his dream is just a dream. Until the day when Admiral Drake responds to a letter by sending a real, live penguin straight to Mr. Popper's house.
It isn't long before the first penguin, Captain Cook, is joined by a second penguin named Greta. Soon, the Poppers have a houseful of new penguin friends. But with a dozen penguins to feed, plus Mrs. Popper and the children, how will Mr. Popper ever make enough money to keep the whole family going, penguins and all?
But Mr. Popper and Captain Cook are nothing if not imaginative, and now it's time for them to dream even bigger . . . and to take the penguin show on the road!
