One morning, Bear decides to visit the post office, knowing that Jeremiah can be slow in delivering the mail and wondering if anything has come. At the post office, he finds a two-week-old postcard that reveals that a penguin named Puck from the South Pole is paying a visit to the Big Blue House; today. Bear hurries home to greet Puck. Everyone there is eager to meet him, but the kids begin to worry when they find his food tastes and his behaviors somewhat odd. They try to play with him, but worry that they just don't understand him. Meanwhile, Tutter learns all about diversity at Mouse School.
