Night Whistle Trick

Night crept over the park gravel, and my legs wanted one quiet mystery before snooze time! I trotted past the empty swings to the big stone drinking fountain, ducking straight underneath into the shadowy hollow! Right against the curved drainpipe sat a hollow green plastic acorn top, tiny and round! I scooped it up with both hands, brought it right to my mouth, and gave a sharp, mighty blow! FWEET! A crisp, hollow whistle buzzed right off the damp stone bricks! It startled me so fast I tumbled backward onto the cool gravel, laughing at my secret night signal!
