"Blyton's Golliwogs were often rude, mischievous, elfin villains. In Blyton's book, Here Comes Noddy Again (1951), a Golliwog asks the hero for help, then steals his car. Blyton, one of the most prolific European writers, included the Golliwogs in many stories, but she only wrote three books primarily about Golliwogs: The Three Golliwogs (1944), The Proud Golliwog (1951), and The Golliwog Grumbled (1955)....
...Once the three bold golliwogs, Golly, Woggie, and Nigger, decided to go for a walk to Bumble-Bee Common. Golly wasn't quite ready so Woggie and Nigger said they would start off without him, and Golly would catch them up as soon as he could. So off went Woogie and Nigger, arm-in-arm, singing merrily their favourite song -- which, as you may guess, was Ten Little Nigger Boys."
