Familiarity of the Other World

How did the Fat Zoog survive? Even though it had been almost a day since then, the Zoog who was named Babyfat was still shivering when he was asked to repeat the encounter. He did not even show much appetite at the chicken thighs offered him. "It was because of my speed and intelligence. I used words to confuse the monster and while it was confounded, I whipped around and leaped over the river. When I looked back, there was nothing there." 

Gu Jun took Babyfat's words to mean that the Black Billy Goat did not give chase at all. The video recorded by Babyfat verified that. The Zoog was not attacked during his escape.
