But, of course, I would not be listing it here if it there was not a mathematical component as well. There are math jokes ("ba(na)²") and mathematical problems ("The hungry Baba Nyani enters the kitchen at night and eats 1/6 of a banana bunch...How many bananas were there at the outset?"). Moreover, the banana girls demonstrate their mathematical ability both by being able to memorize digits of π and by publishing their original mathematical physics research ("Towards a Probabilistic Formulation of the Special Theory of Relativity").

Eventually, the novel's plot extends beyond the lives of just these two children. The threat of the Banana Liberation Front (BLF) brings a hint of espionage into play, a government agency's misuse of statistics provides another opportunity to address mathematics, and references to "President Grump" offer another opportunity for political commentary as well.

Non fictional appendices include "Banana Basics", "Banana Culture" (such as the lyrics to Harry Belafonte's "Banana Boat Song"), "Banana Mathematics" and "Banana Readings".
