After their last bungle with the cave's security, Sunose decided to stick to the back of the group. Sure, it opened him up to being separated from the group or kidnapped by the locals, but it seemed safe so far. He'd start worrying about hostile company once his companions had triggered the rest of the traps, leaving the inhabitants of the cave - if there even were any - no other choice than to appear.
So he waddled about idly, trying to search for any other curious tidbits while remaining as safe as possible. His eyes pried for harmful gadgets, devoting the rest of his assorted senses to finding anything else. Either they'd find something, or something would find them.
