Edid Blyton has a lot to answer for.
In Toytown, Noddy and his friends were forever on the receiving end of the naughty golliwogs' tricks.,..
eexcept for the the one who fell in the stream and was rescued by Noddy, he became a friend, but "chalky the golliwog" had lost his black colour in the water!
So he was a good guy now that he wasn't black.
