The Boing Gadget

I marched right up to the front door trim to investigate the outside breeze, when a curious silver coil caught my eye! It stuck straight out of the baseboard, capped with a little white rubber thimble. Wondering if it was a spring-loaded door lever, I braced my round paws against its tip and leaned in with all my weight. Thwack-boooing! The coiled metal whipped backward with a buzzing twang that sent vibrations tickling straight through my belly! I tumbled backward onto the woven doormat, watching in pure delight as the spring wobbled frantically back and forth like a cheerful antenna.
