AI Video Prompt: Crystal Mech Whale

A photorealistic, cinematic 9:16 vertical video. The shot begins with a close-up POV of a human hand holding a small, transparent, light-blue mechanical crystal whale toy with silver joints and a glowing blue core. The thumb presses the glowing button, activating it, and throws the toy into the calm, dark blue ocean. Upon hitting the water, a bright blue light erupts from beneath the surface. The water bulges and a colossal, highly detailed mechanical crystal whale breaches the surface. The giant whale is an exact, massive-scale replica of the toy, featuring a transparent glass-like body, intricate silver internal mechanics, and glowing blue energy lines. Water cascades realistically off its crystal body as it rises powerfully, opens its mouth revealing complex inner structures, and arcs gracefully through the air, creating a massive splash. The camera smoothly transitions from a close-up to a wide cinematic shot to capture the immense scale. Natural daylight, high-end VFX, realistic fluid dynamics, sharp focus.
