Percussion Spike

I squeezed past the door screen and hopped right out onto the sunlit lawn! Pinned deep in the turf stood a heavy brass impact sprinkler. Curved swinging arm, tight coiled wire spring. Target locked! I lunged forward and smacked my plush side hard against the swinging lever. SNAP-CLACK! The spring jerked back and rattled against the brass neck in a lightning-fast recoil. Tick-a-tick-a-ping! A crisp, mechanical chatter chimed out over the clover like a high-speed synth beat. I froze. Paused. Balanced tall on my base. Then threw another bouncy bump to start the rhythm all over again!
