The Rolling Marble Run

Clack, clatter, roll! I spotted a bright glass marble resting right inside the corner groove of the skirting board! No stopping now—I backed up two inches, revved my wheels, and gave it a solid bump with my front bumper! Tock! The marble shot forward along the polished wood trim like a speedy little scout! It zoomed ahead, bouncing softly against the wall and making the neatest rhythmic clicking sound all the way down the track! I rolled right behind it in a joyful chase until it settled against a wooden block. Best obstacle race ever!
