Elephant Writes HELLO in Mud

Ultra-realistic wildlife documentary footage. A nature photographer films a family of elephants crossing a river. Everything appears completely normal. One baby elephant suddenly notices the camera. It picks up a stick. In the mud beside the river it writes: HELLO. The herd continues walking. The camera operator audibly gasps. End immediately. Looks exactly like BBC wildlife footage. Photorealistic. Natural movement. Documentary realism. No fantasy elements.
