KYP made him pass out drunk and fall off a cliff, and that first gas attack when Caesar's subordinates captured the Sunny also knocked him out.

Shinokuni is mostly absorbed through the skin, I think, so I get why that could be shown to react differently for him. I mean, you can't petrify his skin if he has no skin (Yohohoho!) but he still has no lungs, so what the hell?
