The Missing Puzzle Piece

I trotted inside from the patio and found a giant cardboard jigsaw puzzle spread across the low coffee table! One wavy-edged piece was resting on the rug like a stranded turtle. Explorer rule fifteen: no piece left behind! I hugged the stiff cardboard against my tummy with both paws, scrambled up the wooden table leg, and hopped onto the tabletop. It was covered in colorful, half-finished picture islands! I searched across the printed meadow, spotted a matching notch right along the roof of a painted red barn, and gave my piece a firm double-paw stomp. Click-snap! It locked into the gap without a single wiggle. Mission accomplished!
