My Penguin Osbert in Love

It's love in a cold climate for Osbert the penguin...One morning there's a knock at Joe's door. It's Osbert the penguin. He's escaped from the zoo, and he and his friends (all twenty-one of them) want to travel to Antarctica for a once-in-a-century spectacle: the southern lights. Luckily Joe has a helicopter, for everyone knows that penguins can't fly. But when they land at the South Pole and pile out to watch the skies, it seems Osbert is more interested in something - or someone - else. Can Osbert and Joe still be friends now that Osbert has found love?
