Two astronauts on the moon look up in terror at a giant alien head that is looming over them. The alien's eyes are glowing yellow, and its mouth is open in a snarl, exposing its sharp teeth. The astronauts are wearing their space helmets, and their faces are obscured by the visors. One of the astronauts is carrying a gun, but it seems like a futile gesture against the giant alien. The moon's surface is rocky and barren, with large craters and boulders scattered around.
