A Silvery Bookmark Challenge

I scrambled straight up the side of the wooden bookshelf to claim a high-altitude perch! Right across the lower ledge, a heavy hardcover book was leaning slightly open, sticking out like an arrogant gatekeeper refusing to close its mouth. I didn't hesitate—I dropped into my fighting stance, threw two lightning-fast wing jabs at its thick paper edge, and drove a flying stomp right into the spine! Whump! The heavy pages clamped shut with a hollow thud, and squeezed out from the top corner was a sleek, silver satin ribbon bookmark. Ha! I grabbed the silky strand in my bill, gave it a mighty tug, and tied its loose tail around my belt like another championship trophy!
