Nohno is the only one non-chicken resident of Rooster Island. He was charged with taking care of Bob's pet chicken, Cluckles, when Bob was not able to take care of him anymore. He is also the brother of Yahya, the mushroom addict, and Mehme.
He is possibly a reference to Honorarius, the Roman Emperor, who loved chickens too.
Nohno: Hey, you aren't a chicken! Wait, you're a human! You can help me! Maybe you are the guy who helped my brother Yahya, but who knows, you humans all look the same to me.
Nohno: I really love my chickens, but there is one I just cannot control...
Nohno: His name is Cluckles, he was given to me by a man named Bob before he went to war, but when Bob never came back, Cluckles got angry...
Nohno: He's really dangerous to keep on my lovely island, so I keep him in my basement...
Nohno: I want to take care of him but my wife says it's too dangerous. Where's my wife you say? Oh, I think she's around here eating some grain.
Nohno: Anyway, I need you to go down there and... take care of him for me. I would really appreciate it.
