The Bear with a Sore Head — William Forde

Boris the brown bear started life as a pleasant and good natured bear who was a good neighbour to all the other creatures of ‘Marfield Meadow Vale'. Then, suddenly, he turned into a nasty bear with a sore head who made his neighbour's lives a misery. All the other creatures try to discover what brought about this drastic change in the bear's behaviour, so that one they find out, they can change Boris back to the pleasant bear he once was.
