5-second ultra-fast cinematic transformation, vertical 9:16, one continuous seamless shot. A hand holding a cute capybara keychain suddenly swings it aggressively toward the camera. The camera rapidly pushes in and performs a dynamic 360-degree orbit following the spinning keychain. As it spins, the tiny silicone capybara explosively expands into a gigantic living photorealistic capybara. Its smooth surface seamlessly transforms into detailed brown fur while preserving its sleepy eyes, pink cheeks and adorable expression. The background rapidly transitions from the original room into a lush tropical jungle through natural motion blur. The giant capybara lands heavily on the ground, scattering leaves and dust. The camera whips upward as the enormous capybara suddenly lunges its face toward the lens, stopping inches away with a funny, unimpressed expression. Extreme speed ramping, powerful physical momentum, rapid acceleration, realistic gravity, fluid camera tracking, cinematic motion blur, seamless morphing, realistic fur physics, dramatic golden sunlight, 35mm lens, photorealistic 8K. No cuts, no teleportation, no flickering, no extra limbs, no facial distortion. Maintain perfect character consistency throughout.
