אוטובוס הופך לזחל רובוט ענק

an old, green, oversized, and extra-tall American-style bus is parked in a dilapidated parking lot in a forest. A young Asian driver slams on the brakes, looking tense and speechless. The bus begins to violently disassemble and reorganize from the inside out, transforming into a grumpy, evil Cybertronian mechanical giant caterpillar. The driver's cabin reassembles into a mechanical head, the windshield becomes its glasses, and the bumper turns into a chin. Both sides of the mouth use hydraulic devices, the tongue is made of seats, and the teeth are formed from broken orange handrails inside the bus. The headlights transform into its eyes, and the entire body is composed of large vehicle components in segments. It spits the driver out of its mouth, bites his head, and tosses him into the air to land on its back; the driver grabs the handrails on the back to stand firm. The mechanical giant caterpillar strikes a cool pose, roaring and spitting sparks. The windows and tires remain intact. The transformation process is aggressive, with the body constantly twisting and crawling, parts rubbing and sparking, dust flying, and valves venting air. The camera moves continuously from the cabin to the exterior, showing the mechanical body's massive yet slender stature. Use a realistic visual style for the generated material, employing a humorous yet terrifying transformation style, accompanied by intense and shocking background music.
