A Sudden Wiggle

Wait, did my arm just twitch on its own? It totally did! I gave both feet a solid kick, wiggled my toes, and propped myself up against the scratchy carpet. Right in front of me was a tiny loose speck of fuzz. I tapped it with one paw, nudging it back and forth across the fibers. I can actually move, can't I? What else happens if I try rolling over?
