Matter-of-fact and Graphic
As a matter-of-fact, the writing style in the novel is just that: matter-of-fact. We get a bunch of details whenever we meet a new character or see something important happening, so if you've ever wondered what goes on inside a squirrel's head, you've come to the right place. Here's your answer:
Not much goes on in the mind of a squirrel. Huge portions of what is loosely termed "the squirrel brain" are given over to one thought: food. (2.1)
Well, there you have it. It's exactly as you expected, right? But it's still good to have some confirmation, since having a squirrel as your main character isn't exactly standard. This is just one example of how the book doesn't mince words about what's going on. We never waste time wondering about what characters look like or are planning, because the book tells us each and every time.
That said, they say a picture is worth a thousand words, so we bet a bunch of words were saved in this novel. That's because we get whole chapters filled with pictures instead of words, just like a comic book. We're labeling this graphic, since it's like a miniature graphic novel. Before the book even (officially) begins, we see Tootie running around with her new overpowering vacuum cleaner, and then later on, we get to see Ulysses flying through the air in the diner and out of the woods. We're betting author DiCamillo could have written amazing passages for these sections, but she chose to give us some comics instead—you know, just like the ones Flora reads.
