Skyfire grimaced at the words 'walking dead' and then sighed as Tsukishima finished the explanation. Really, after the monster pumpkin he shouldn't be surprised but...

"Lovely..." Peering into the cave a bit more, he huffed and drew attention to his back with a ruffling of the feathers on his wings. "Climb on up then. I'd rather not see what will happen if you go in there without any armor... and then we'll see just what's in here."

His claws leave a few deep gouges into the stone as he tries to settle himself, because who knew what else they'd find in there? Skyfire wouldn't say it, but he's actually a bit nervous. If it was just himself going in, he'd be less worried.
