Corporal Cecil Wormsborough St. John Nobbs is probably human. He was the third original member of the Watch at the start of Guards! Guards!, and has adapted well to the changing nature of the Watch. He is a man of many parts - he does folk dancing, and is a member of the Peeled Nuts (Ankh-Morpork Civil War Reconstruction Society). Apart from that, he's just Nobby, and thats all that can be said.
