The Resonant Spring

A tiny metallic spiral jutted straight out from the baseboard. Grrr... Motionless sentinel guarding the corner. Unacceptable. I charged forward, lowered my snout, and slammed my central forehead directly against the rounded rubber tip. BOING-G-G-G! A violent, frantic tremor exploded across the metal coil. The rubber cap whipped back and forth in a frantic blur, buzzing intensely against my scales. Glorious high-frequency twang! Both of my arm-heads darted in to clamp the vibrating coils, but the shuddering spring bounced furiously, rattling my talons against the skirting board. I struck it once more with my left snout. BOING! The entire hallway rang with its humming recoil.
