Casting the Dust Motes

I was gliding across the wide floorboards when I caught sight of hundreds of floating dust motes dancing right in the soft sunbeams. My mind instantly raced with a whole movie concept: a deep-sea documentary where the speckles play wandering stars! I squished my soft belly against a notepad and pushed a stubby blue crayon around to sketch out the opening scene. Then I turned to the wooden frog sitting by the shelf and blurted, 'Hey, do you want to play the wandering captain, or should I cast the clock instead?' I need to get everyone's permission before filming starts!
