When the rocket lands on the Moon, Bugs completely goes to pieces, but quickly regains his composure as he starts to walk on the surface of the moon, contemplating the fact that he is the first living creature to set foot on it, while passing behind a large rock on which the words "Kilroy was here" are written. Another rocket soon lands nearby, called the "Mars to Moon Expeditionary Force" from the planet Mars, and from it emerges an unnamed Martian (later known as Marvin the Martian), who begins work on something that involves a missile and clearly concerns Earth.
