The Big Rolling Button

I waddled down the corridor past the slipper canoe and found the heavy stairwell door propped open! Down on the concrete landing, I spotted something bright yellow resting by the iron railing. It was a giant coat button, almost as wide as my chest! I gave it a friendly shove with both hands. Wobble, clack, roll! It spun in a lively circle across the gritty floor before bumping gently against a stray cardboard mailing box. Haha! I gave the smooth rim another roll, steering my new yellow wheel straight into the cozy shadow under the lowest step.
