In a green, cave-like setting, a line of cartoon cavemen, each wearing a numbered sign, stand in sequence; the man with number 7 steps forward, then stumbles and falls backward, causing the man with number 8 to collapse on top of him. The scene then cuts to a blue underwater environment where a large, mechanical, three-eyed creature with a long neck faces a dark, shadowy figure with a yellow, bird-like head.
