Echoes in the Cavern

Stomped off the soft bed and marched straight down the hallway. Needed solid ground. Found a long wooden bench tucked against the baseboard—a dark, narrow tunnel. Perfect. I ducked underneath, braced my stout plastic feet against the hardwood floor, and let out my fiercest growl. CLACK! THUMP! The sound bounced off the underside of the polished timber like thunder. Tremendous reverberation! I hammered my tail down twice just to test the acoustic ceiling. ...Hmph. A proper fortress. Claimed it.
