The Missing Piece

I scrambled down from the hallway bench and marched straight to the low coffee table in the living room! A colorful jigsaw puzzle was laid out across the wood, with just a few empty pockets left along the top border. Right near the corner, I spotted a single stray piece resting face-down. I gripped its sturdy cardboard edge with both hands, flipped it over, and found a patch of bright sky blue! Scanning the interlocking grid, I found the exact matching slot. I nudged the piece into position and gave the tab a firm, flat stomp with the sole of my boot. It locked flush into the seam without a single wobble!
