The joke here is that during the entire gameplay I've only picked up two carrots and somehow beaten the game, implying that Noah had survived the flooding (which took approx. 150 days) feeding on just those two carrots I brought with myself earlier
Ohh okayy :D The idea behind hunger is that you lose an animal when it runs out. And I mean Noah is like 900 years old he probably doesn't have much apetite either.
