What if blue whales released glowing seeds that transformed everything

In the deep open ocean, a pod of enormous blue whales release thousands of glowing seeds that instantly transform every surface they touch. A visible wave of change spreads outward with each seed while untouched areas remain clearly different. Sun shafts, bubbles, plankton, and distant divers establish their scale. Follow one seed through the air, then widen as the transformation races across the scene.
