#my pet theory is Colfer decided that the Paradizos are from Cagnes-sur-Mer because of Renoir

Not to mention, the word "BoBo" usually explicitly or implicitly has a Parisian character -- and the Paradizos are from Cagnes-sur-Mer in the south of France!

[Eoin Colfer, The Last Colony]

Minerva using the nickname "BoBo" for her little brother "Beau" cracks me up because of the following:

[Scott Gunther (2016). “How and Why ‘Bobos’ Became French” in French Politics, Culture, and Society:34(3)]

"Do you know what a “bobo” is? If you are French or an American who has spent significant time in France, you probably do, but if you are an American without much experience in France, it is likely that you do not, even though the term was originally created to describe an American phenomenon. The word “bobo” is short for “bohemian bourgeois,” a curious combination of two terms that would normally be placed in opposition. It was coined in 2000 by David Brooks in his book "Bobos in Paradise: The New Upper Class and How They Got There". He defines the bobo as a cosmopolitan, upper-middle-class individual who espouses liberal politics (especially with regard to social and environmental issues) and eschews conspicuous consumption, spending large amounts of money instead on discreet luxuries. In a nutshell, as Brooks recently told me in a telephone interview, “the shorthand version is that bobos are people with ’60s values and ’90s money.” The book received media attention in the United States when it was first published, but the term bobo never really took hold in the American lexicon, at least not as much as it did in France, where soon after Brooks’s book was translated into French, in 2000, the term took off to the point where most people, French and American, have almost entirely forgotten its American origins. In his book he explains that, “when faced with a tension between competing values, [bobos] do what any smart privileged person bursting with cultural capital would do. They find a way to have both. They reconcile opposites." [...] [T]he bobo is portrayed in a negative light, as a hypocritical, superficial, urban dweller. One gets the sense that a bobo is almost always someone else and understands why people would be generally reluctant to identify themselves as such."
