The life of a family becomes gradually "penguinized" when every day, beginning on the first of January, a mysterious package arrives with a new penguin. As the penguins increase in number, the family attempts to find humorous new solutions to deal with the increasing population of birds that need to be fed, organized and housed. Over the months, the comedy continues as penguins play piano, watch TV, swim in the backyard pool and take over the house. 365 days and penguins later, on New Year’s Eve, the doorbell rings and Uncle Victor, an ecologist who has been sending the penguin packages, explains he needs to protect the birds whose Antarctic habitat is gradually melting due to global warming. Although to the relief of the family, he leaves the house with a truck full of penguins, another mysterious, yet different, parcel soon arrives. This hilarious story with zany illustrations to explore is a fun adventure in math and counting that also conveys an environmental message to young readers.
