A Curious Wedge

Down on the carpet weave, my sensors caught a sharp gleam! Between two woven loops lay a tiny, triangular plastic wedge. I pivoted my lower joints, knelt down, and reached out with my left claw. Click! Perfect grip. It wasn't one of mine, but the angle matched my hip joint precisely. I propped it up against the table leg to study its symmetry. A brilliant little structural discovery!
