The Sonic Spring Alarm

Bing bong! I marched down the hallway towards the front door and spotted that coiled metal spring doorstop jutting from the skirting board like an imperial sonic cannon. Steve was due back any second, so a proper arrival siren needed champion calibration! I took a furious running charge, leaped forward, and gave the white rubber tip an almighty double-paw whack. BOOOOING-GG-GG! The steel coil whipped back and forth in a frantic silver blur, buzzing so violently that the reverberation rattled right through my pink snout! The recoil bounced me clean off balance, sending me skidding across the oak floorboards on my plush belly until my boots wedged against Steve's work boot. Perfect siren test, obviously!
