A Solid Tap
One second I was stiff as a board, the next my arm joint gave a quiet pop. I could actually flex. My left paw was already gripping a tiny red bottle, so I gave my wrist a quick downward flick just to see what would happen. Clack! The base of the bottle tapped firmly against the wooden plank under my feet. The big guy standing right behind me didn't react at all, totally frozen. Suits me fine. The sound was loud, clear, and proved I'm not just sitting here looking decorative.
