It think reg is just going a bit senile, I'm sure he just meant it terms of noddy characters.
Indeed, apart from the senile bit, you'll be telling me that the saintly Enid Blyton was a racist next.
I did get a bit excited at the news, that a previously unknown Blyton book, Mr Tumpy's caravan has been found....I suppose it's too old to be based on the adventures of axs.
