Oh really? Jake's ears perk up at that. "Sometimes, huh?"

Okay, so only sometimes means it probably isn't a body part like he'd been thinking. Five headed creature still makes him think fingers or toes though; not much else he can think of that'd fit that description. So something that covers them. Made of leather, maybe? "Gloves? Or shoes?" Not that the Na'vi tend to use either, but Jake hasn’t forgotten being human. Basic equipment is easy.
