A Rolled Discovery

I waddled off the rug and found a shiny, clear glass marble resting right in a sunny patch of wood! I bumped it forward with my chest. Roll, roll, click! It spun in a quick circle before knocking gently against a table leg. I stood tall, balanced neatly on my orange feet, and watched the tiny speck of rainbow light trapped inside it shimmer. It stayed perfectly round even after moving!
