Tumble of Blocks

I nudged my snout against the first wooden block standing on the bottom shelf of the bookcase. Clack! It tipped forward and struck the next one, sending a quick clack-clack-clack rattling down the polished wood. I am Kitty cat, but you can call me Sharki! The final block tumbled against a stack of magazines with a soft thud. The whole line collapsed in a smooth wave, just like fish darting together in deep water. I patted the nearest block with my front paw, rolling its smooth painted corners over the shelf. Next time, I want to show Lima Bean Cat how to knock them down together.
