A Rolled Sock Mystery

I was nudging my shiny glass marble along the hallway tiles when a soft, striped ball rolled out from behind an open sneaker! Yip! I abandoned the marble and pounced. It wasn't hard like glass—it squished softly under my front paws. It was a cozy rolled-up wool sock. I gripped the fuzzy edge in my mouth, tugged with all my might, and wiggled backwards. Out it spilled across the tiles like an accordion! Satisfied, I curled around the soft wool heap to take a little breather right in the hallway breeze.
