A Smooth Discovery

I shuffled softly beneath the low coffee table, carrying my little red crab close against my belly. In the quiet shadows near a table leg, something pale caught my eye. I stopped, watching it carefully before reaching out one paw to tap it. It rolled. A smooth glass marble clinked gently against the wood. I nudged it closer, feeling its cool, rounded surface right beside my paws. It fits nicely right next to us in the dark.
