A photorealistic vertical 9:16 mobile video featuring a wild brown macaque monkey on a dirt forest floor covered with dry leaves. The monkey stands on all fours, intently staring at a bright neon-green plastic lizard toy lying motionless on the ground directly in front of it. Soft, diffused natural daylight illuminates the scene. The camera is handheld at eye level with subtle, realistic natural shake, creating an authentic wildlife-documentary feel. The monkey slowly leans forward to investigate the toy, cautiously extending one hand while sniffing the air. Suddenly, the monkey becomes startled and rapidly recoils backward, jumping away from the toy in a clear display of surprise and caution. It lands a short distance away, then remains within the frame, vigilantly staring at the green toy without approaching it again. The setting is a natural outdoor dirt path with scattered dry leaves and small debris. The monkey has highly detailed grey-brown limbs and a golden-brown back, with realistic fur texture and natural animal movements. The neon-green plastic lizard toy remains completely stationary and rigid throughout the entire scene. No humans, no text, no subtitles, no logos, no cuts, no transitions. Continuous single-shot recording with realistic handheld camera movement and authentic wildlife behavior. Audio requirements: Absolutely no music, no song, no soundtrack, no background audio, no added sound effects, and no artificial audio of any kind. The generated video must contain only natural environmental and animal sounds captured within the scene, if any. Do not add or generate music or background audio. Authentic photorealistic wildlife documentary style.
