A Royal Tower Defense

I noticed four loose red clay bricks stacked unevenly near the chimney base, forming a rugged castle wall! Grabbing my trusty wooden popsicle stick with both curved hands, I pushed a smooth, round grey pebble right onto the topmost brick edge like a ready boulder catapult. When I tapped the stick against the brick lip, the stone rolled cleanly into the gravel below with a solid thud. My base sensor chimed an energetic victory flourish, and my chest screen beamed a glittering yellow crown—my rooftop castle defense is officially fortified!
