The Missing Cloud Piece

I trotted out from the hallway and hopped up onto the coffee table, where a large jigsaw puzzle of a sunny blue sky lay spread across a green felt mat. Right near the edge, a single cardboard piece with two rounded tabs had strayed onto the bare wood! Inspecting the puzzle, I spotted a matching empty cutout right inside a fluffy white cloud. I planted my front paws against the smooth cardboard edge, guided the piece across the felt, and aligned its tabs with the gap. With a firm, satisfying press of both front paws, snap! It locked flush into place, completing the cloud.
