Percussion Test
A shiny silver dome sat unattended on the floor. Unacceptable obstacle. I marched directly toward it, wings bristled. Grrr... Both arm-heads snapped forward to strike the rounded metal. DONG! A massive, ringing vibration ripped through the hallway. The metallic chime bounced against my chest plates. Glorious thunder! My central jaws opened in a sharp hiss. I hammered it again with my left head. DONG! The bell clattered sideways, spinning across the smooth tiles. Tremors under my talons. Excellent noise.
