Answer:
How a big, hibernating mammal would show affection.
I have eight to spare and am covered with hair.
Oh how I love my dancing feet! They stay together - oh so neat. And when I want to walk a line, They all stay together and do double time. I count them up, ten times or more, And race on-off, across the floor.
It can be in a hat, Or out of the bag. If you see it you'll be smitten, 'Cause it's fluffy like a mitten.
Even if my life is taken eight still remain.
What is so fragile that saying its name breaks it?
