A Doll Inside a Doll

I grabbed the painted wooden head of a round folk doll resting on the shelf edge and gave it a solid heave! Pop! The hollow painted shell split right open, and sitting snug inside was another identical doll, only half the size! I didn't stop there. I planted my feet against the wooden base, tugged again, and uncovered an even tinier third one! I lined all three up along the polished oak surface from tallest to smallest, standing at attention like a brand-new drill squad. We are ready for action!
