I looked up the meaning of "quilly" and found two definitions:
1. Quilly is used to describe something that is limitless or truly timeless; or
2. Abounding in quills.
I believe both definitions describe the porcupine in different ways.
The photos below were taken late afternoon, early evening some weeks ago, while leaves were green on some trees. I have added captions to capture those porcupine expressions.

PHOTO #2 - "OKAY, IF YOU INSIST"

PHOTO #4 - "AND SLEEPIER"

PHOTO #5 - "NOW I LAY ME DOWN TO SLEEP"
