Humbug lives with his family in the marsh. The horses roam wild and are very shy. A photographer takes photos of them for a calendar. People really like the photos. One day the photographer brings a boy in a wheelchair along. Humbug forgets to be shy. He does all sorts of silly things to make the boy smile. It becomes a very special day and the boy promises to visit again.
