The Missing Sky Piece

I hopped back inside through the lobby just as the hallway grew quiet. Up on the dining table, a half-finished puzzle was spread out across a roll-up green felt mat! I bounded from the chair cushion right onto the oak surface to inspect the spread. So many scattered cardboard shapes! One curved blue piece with two round tabs immediately caught my eye. I leaned forward, nudging it carefully with my nose across the smooth felt toward a blank gap in the printed sky. Slide... click! It slipped right into the notch with a snug little snap. One cloud corner, officially completed!
