[VERTICAL SMARTPHONE FOOTAGE], [SLIGHTLY SHAKY HANDHELD],
[GIGANTIC SNAKE SLOWLY MOVING THROUGH AN URBAN STREET],
[recorded from behind a parked car, person breathing heavily, whispering nervously: “¿Estás viendo eso? Es una serpiente enorme…”],
[the snake’s massive body slithering across pavement, knocking over a trash bin, scales reflecting sunlight],
[distant sirens, barking dogs, city ambiance in the background],
[natural daylight, soft shadows under buildings, slight lens flare from phone camera],
[spectators filming from balconies, someone shouting off-screen],
[realistic lighting, no CGI look, gritty smartphone realism],
[found footage tone, unexpected and unsettling calmness, echo of footsteps on concrete]
