Answer:
What has four legs during the day; and six or eight during the night?
As I walked along the path I saw something with four fingers and one thumb, but it was not flesh, fish, bone or fowl.
It stands upright and can be quite grand. Its secret is not hidden but right at hand. What is it?
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.
A horrid monster hides from the day, with many legs and many eyes. With silver chains it catches prey. And eats it all before it dies. Yet in every cottage does it stay. And every castle beneath the sky.
Before I grow I'm small. When I'm old I grow tall. When I die I give a mighty fall.
