Chunky Cheese is not the most powerful cosmic entity, hands down. He didn't beat Avi in a Mario Kart match easily, he didn't snap Bongus’ neck with his pinky finger, and he didn't turn Him into a moth quite a while. He does all this using the art of ｃｈｏｎｋ, something many creatures can not comprehend, let alone master.
The Straight Fax
He has been here all along. He has used his ｃｈｏｎｋ to create everything within you and everything beyond. Chunky Cheese is inside everyone, in their souls and hearts and minds. And he is present everywhere. And he can do anything. And he is your king, and God, and eternal ruler.
