A giant organic octopus crowds inside the coastal streets of Santa Monica, several massive tentacles planted across wide beachfront intersections stabilizing its weight; one tentacle lifts a crushed section of beachfront hotel structure and slams it sideways into another building, sending cascading glass and debris outward; another tentacle sweeps low across Ocean Avenue, flipping cars and buses aside like toys; ocean water surges inland from the Pacific, flooding streets and forming fast-moving currents around vehicles, palm trees, and debris; the octopus lowers its head toward the street, eyes scanning, breathing heavy with subtle body expansion and contraction, wet skin reflecting harsh coastal daylight; a tentacle suddenly strikes downward, cracking open the road surface, exposing underground pipes that burst violently, water and steam shooting upward; people run away from the creature with backs facing it, slipping on wet pavement, some falling and scrambling up in panic; helicopters hover farther offshore, maintaining distance through mist and smoke; camera shifts to a slightly elevated angle showing multiple tentacles interacting simultaneously with beachfront buildings, one wrapping around a glass hotel tower and slowly pulling it down with visible structural bending before collapse; final moment shows the octopus pausing briefly amid chaos, tentacles slowly moving, surrounded by collapsing structures, rising smoke, crashing waves, and flowing seawater, cinematic slow-motion debris fall, dramatic scale and tension, ultra realistic organic motion, volumetric sea mist, heavy atmospheric destruction, epic disaster tone
