When Joe's parents told him the family would be moving, Joe took it in stride. Moving to a new house would be an adventure, nothing to worry about, right?

But then they dropped the bomb: they weren't simply moving to a different house down the road, or even one in the same town. No, they were moving to a new country

They urge Joe to make new friends and try to fit in, not seeming to understand that Joe doesn't want new friends--he just wants his old friends. His friends back home already love and accept him for who he is (wheelchair, bad jokes, and all ). Who would want to start over?

At the airport, Joe's suitcase goes missing, and he is sent home with a giant, friendly, funny polar bear instead. Mister P. will be Joe's new friend, even though Joe isn't quite sure how the two of them will pull this off. What could a polar bear and a kid have in common?
