The Acorn Roll

I bolted right out through the open garden gate to see how far the sidewalk went! Right on the sloping concrete curb, I spotted a plump, glossy brown acorn wearing a bumpy little cup cap. I couldn't resist giving it a running shove with both paws! It wobbled forward, picking up speed, and rattled down the asphalt with a snappy skitter. Before it could slide right between the bars of a metal storm drain, I flung myself forward and trapped it against the curb with my back foot! It let out a tiny, hollow *clack* and stayed put.
