I first read this entertaining book, then called simply "The Minnipins", in a Puffin paperback, more years ago than I care to count. Recently I have dusted off my battered copy to read to my four year old daughter.
The story is as rewarding and involving as I remembered, but the sudden, savage genocide of the bad guys, the rather two dimensional "Mushroom People", was unexpectedly bloodthirsty. I do not remember being at all bothered by this as a child, but as an adult reading it to a child, it felt disturbing. Maybe this is a case of being needlessly over-protective...I re-read this book many times, and it did not turn me into a psychopathic killer. It did not even put me off mushrooms...Maybe we are used to a less graphic depiction of violence in children's books, a modern day Mowgli would probably befriend Sher Khan and save him from extinction. Even so, the battle scenes in this novel are jarring, coming as the culmination of a tale of prosaic, even mundane, everyday activities.
The real joy of the book is in the characterisation, particularly Muggles and Mingy.The scene where Mingy proposes to Muggles is perfectly judged, and quite touching. The message of rebellion being justified when faced with officious conformists is nicely put across, in my opinion; Painting your door red, in a sleepy village where all the other houses have sensible green doors, is an image and a sentiment even the youngest child can recognise!
The Gammage Cup itself is a minor part in the story, and a poor title in my view, but, then, for me, it will always be "The Minnipins", so I suppose that doesn't really matter.
One point that troubled me when I first read it, and still seemed mysterious when reading it now : What is "Walter the Earl" the Earl of ? This kind of unanswerable question should not be left hanging in Children's literature...it is unfair to parents!
