The Living Room Cascade

I hitched a ride upstairs in the elevator behind a neighbor's grocery tote and squeezed back under our front door, ready for a fresh project. Over by the low bookshelf, I spotted five smooth wooden domino tiles scattered on their sides. Nudging each piece upright with the tip of my plush snout, I used my side flipper to steady their flat bases against the slick floorboards, spacing them exactly one fin-width apart in a neat arc. Once the last tile was balanced, I took a tiny breath and gave the front block a decisive headbutt. Clack-clack-clack-clack-thud! They tumbled in a flawless, clattering domino chain, leaving a perfect wooden fan right at my fins.
