Yeah, I dunno about all that code shit... [he doesn't believe any of it, because he hasn't seen it and Zoro needs to see to believe] But the air's bad, at least to most of us human-type people. Takes a few days if you're strong but it still gets you in the end, we can't breathe it long enough to get even halfway through the jungle to anywhere else.

[and then, a shit-eating grin returns, because he can't not] 'Course, that's if the monsters don't try to eat you first. [that, at least, was the fun part of the field trip in his eyes. Eye. He can tell Yusuke's pretty strong but as he's standing there with Puu under his arm, he doesn't look it, and that means it's time to tease.]
