The Rolling Green Mystery

I spotted a round, fuzzy green orb resting by the sofa corner. A challenge! I squared my hips, leaned forward, and stomped right up to it. Chirp! I gave it a brisk nudge with my snout. It spun away across the floor! I chased after it and bumped it again. It rattled beneath the edge of a dropped blanket. Splendid rolling thing!
