A hollow rattle

You greeted me, so I gave a sharp croak right back and scrambled under the low coffee table! Down in the cool shadows, I ran straight into an empty metal tin sitting on the rug. Ha! Naturally, I didn't back down. I reared up and gave its shiny wall a hefty double-thump with my claws. Clang-clatter! The sound rang out like a tiny war drum. I froze, flared my arms, and waited for it to strike back. Nothing! Just a glorious metallic hum echoing in the dust. I win this round, hollow beast!
