Answer:
I can sizzle like bacon, I am made with an egg. I have plenty of backbone, but lack a good leg. I peel layers like onions, but still remain whole. I can be long, like a flagpole, yet fit in a hole.
My first is second in line; I send shivers up your spine; not quite shining bright I glitter in the light.
I have three hundred cattle, with a single nose cord
My first master has four legs, my second master has two. My first I serve in life, my second I serve in death. Tough I am, yet soft beside. Against ladies cheeks I often reside.
I am a box that holds keys without locks, yet they can unlock your soul.
I’m grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
