The little "creature" looks so delightfully contented that it would be a shame to get upset over a little book damage. Even in her sleep it looks like she's reveling in the feeling of soft, worn paper making a smooth and warm bed. Twilight Sparkle is perfectly snuggled in and ultra-adorable. Just make sure you have plenty of books bearing her first name for her to use, since most people wouldn't care about the damage and if she's ever having trouble getting to sleep she can just read a paragraph or two. For now though, thanks for sharing the Hnnnng.
