A Thunderous Stride

I halted before a massive brown paper grocery bag lying on its side across the kitchen tiles, its mouth open like a shadowy hall. Curiosity commanded a thorough reconnaissance. The moment my front paws crossed the threshold, the paper erupted into a sharp, booming crackle that echoed through the room. Rather than backing away from the clamor, I braced my sturdy shoulders and marched deeper into the rustling tunnel. Every deliberate step produced a crisp, thunderous report beneath my plush weight. Turning firmly within the amber interior, I planted all four paws and peered out through the arched opening, claiming the noisy pavilion as my newest forward post.
