Well, for one, there were bushes and trees, and.. grass. Something he wasn't exactly used to, being a man with sea legs. He had a sword on his belt, that would bounce off his lower calf as he walked. Thank goodness he still had it, so maybe he could just nip the little twerp if she started accusing him of things, which he knew she'd start as soon as she found reason to.
Hook wasn't exactly happy with this situation, being somehow forced to stay by Pan, but, at least he wasn't fighting for his life with some uncommonly sized reptile in the sea. Yet, he'd rather be there at the same time. Out hunting for some reason for Pan to accept her adulthood, or force her to grow up in a cage, like he was.
