My boys "nest" and do some of the same silly things Lola does. They hold the blankie in their mouths while they work with their paws to scratch up the nest. Most of the time they accomplish absolutely nothing with all of their hard work.
When Max was a pup, he attacked his bed every evening. He hated for the day to end, so he would have a little tantrum and go after his bed. I miss his puppy antics.
