Mr Popper, a great fan of arctic expeditions and explorers in general, one day receives a surprise in the mail from an Admiral he admires: a penguin. He promptly dubs it "Captain Cook" and happily settles it into the icebox (freezer), but, well...if you give Mr Popper a penguin...
This work includes the following tropes:
- Eat the Dog: When the Poppers begin to run low on food, the possibility of eating one of the penguins comes up, but it's shot down when even Mrs. Popper agrees she wouldn't like it.
- Everything's Better with Penguins: While the penguins cause many difficulties, their playful antics ultimately add fun and adventure (not to mention money) to the lives of their owners.
- Hey, Let's Put on a Show: The Poppers solve their money problems by teaching the penguins a routine and taking it on the road.
