In Hatchet, Brian has no choice but to explore. After all, how stupid would he feel if there was a Dairy Queen on the other side of the lake, and he spent the whole summer scarfing down raw turtle eggs because he didn't know it was there? But more than physical exploration, the book shows Brian exploring the mental boundaries of his world. Deep, right? Again and again, we see him discovering new ways of looking at things, new possibilities for how to understand the world around him. That's the kind of exploration that Shmoop knows something about.
Brian's ability to think creatively is one of the most important tools he has in his quest to survive.
Let's be honest—Brian doesn't do that much physical exploration while he's stranded. Come on, Brian, live a little.
