I just realized the double meaning of Nobby’s name

31 books down and i finally realized there is another double meaning behind Nobby’s name. Beside Nobby and Colon being a “bit of a knob” and “a bit of an ass” respectively. A “Nob” is short for “Nobel” in British slang, so his name could also mean “Richie Rich” which is excellent incongruous with his general behavior and appearance. Another layered joke in perfect plain sight
