A Twanging Coil

I tapped the little rubber tip of a silver coil sticking straight out from the white baseboard. Boing-g-g! The whole spring buzzed back and forth so fast it turned into a shiny blur, tickling right against my stubby arm! Poyo! I pulled back in surprise, then hopped forward on my red feet to give it another firm pat. The metal sang out with a funny twang that rattled the floorboards under my tummy. When it finally slowed down to a gentle shudder, I gave the rubber cap a curious squeeze, giggling at the quiet hum still buzzing inside.
