The text is not hand drawn, but more of a Comic Sans style font that young readers will find appealing. The plentiful line drawings exude energy, and there are also other, larger font styles to highlight words, reminscent of Geronimo Stilton but rendered in black and white. Freddy is portrayed as a fairly standard, human shaped robot who looks just like his classmates in his school uniform, aside from his robotic head with big eyes. And, you know, the rocket boosters.
As an adult, I wondered why Ms. Sharma didn't just reprogram Freddy so he would be well behaved like his older brother, but this is never addressed, and Freddy's eventual breaking of the rules ends up saving the day, so he is never really punished for his actions.
Notebook novels about robots tend to lend themselves to series like Lerner's very clever EngiNerds, Richards' Robots Rule, and Patterson's House of Robots, so it is not a surprise that Freddy vs. School also looks to have another book in the works.
