A Shiny Domino Run

I leaped down from the fluffy sock pile and bolted toward the coffee table where a handful of metallic magnetic building tiles were scattered! Obviously they were not meant to lie flat, so I scrambled over and hauled them upright on their skinny edges, clicking them into an alternating zigzag line! My little black feet nudged the final triangle into place, but I lost my balance, leaned too far forward, and boop—my forehead tapped the first tile! Clack-clack-clack-snap! The whole shiny line collapsed in a dazzling domino cascade, clamping together into a neat geometric rainbow ring right around my feet!
