Maybe it's taking a picture of Godzilla's face and shoulders, converting it to black and white (not grayscale), and then doing an ASCII representation of that. A dark Godzilla on a light background would look sort of like that after an unsophisticated conversion to black and white.
I wondered if it was starting with the top but then it's length limits kicked in and it decided the response was getting too long, so it jumped to the conclusion.
