The Whispering Paper Loop

I scrambled into the shadowy gap behind the sofa, hunting for forgotten corners! Right near the baseboard sat a crisp brown cardboard toilet paper roll, standing upright like a hollow tower. Naturally, I bounded forward and pressed my nose straight against the circular opening. 'Pika-chuuu!' I shouted into the dark tunnel! Whoa—the hollow tube answered with a loud, buzzy echo that vibrated right into my cheeks! I gave it an enthusiastic shove with my paws to hear it speak again, but wobble-roll! The tube tipped over and went tumbling across the hardwood, leaving me scampering in gleeful circles behind its bumpy wooden trail!
