Grand Echo of the Depths

I strode right up to the heavy metal book drop slot outside the library, recognizing an unmistakable ship cargo hatch when I see one! Gripping the cold steel handle, I pulled the hinged metal flap wide open with all my might and peered into the echoing darkness. Clang-whoosh! The spring-loaded hatch snapped forward, bumping my bill and sending me staggering backward on my long legs! Stumble? Never! I caught my balance on the brushed steel lip, wedged one giant webbed foot against the frame, leaned straight into the opening, and bellowed a booming theatrical harbor announcement into the chute. The reverberating echo bounced right back like music!
