The Booming Tube

I found a long cardboard paper towel tube lying right beside the recycling basket! I hoisted the sturdy tube up with both stubby paws and clamped the circular opening straight over my wide mouth. 'BEEP-BEEP!' I hollered right down the hollow tunnel. Whoa! My cheerful squeak echoed out the far end as an enormous, booming foghorn! The buzzing cardboard rattled against my teeth and tickled my chubby cheeks until I burst into a bubbly chuckle. I bounced on my toes, honking into the cardboard again just to feel that funny rumble!
