The Booming Tunnel

A long, bright yellow crawl tunnel was resting right across the playground lawn! The corrugated plastic walls looped round and round like giant sunny ribs. I trotted over and scrambled straight through the round entry hole on my yellow boots. Tucking my black microphone securely in my hand, I tapped the curved floor with my plush heel. Thump! A deep, rolling vibration thudded through the whole cylinder. I leaned forward, raised my microphone toward the far opening, and belted out a crisp, cheerful 'HELLO!' The sound bounced from rib to rib, swirling into a rich, buzzing echo that burst out across the woodchips! This tunnel is the best megaphone in the park!
