Round I sit, humble in the ground, break through my skin and treasures are found. I bring tears to some, joy to the cook, layer by layer, reveal my hidden look.

Your car is well tuned if you can stop on me. I am extremely common and abundant when I am a dozen.

Dogs famously do it, Humans wear it, For style or through misuse, I become holy.

I have legs but don't walk I hold you steady

I swallow dough and breathe out heat, A metal mouth where meals are sweet. I don’t eat, yet I help you dine; What am I, warm and built to shine?
