Looney Tunes

The plot of the cartoon involves Duck Dodgers' search for the rare element Illudium Phosdex, "the shaving cream atom." In the future, the only remaining supply of the element is on the mysterious "Planet X," which fortunately is found when Dodgers follows a path leading from Planet A to Planets B, C, D, and so on. Dodgers is about to claim Planet X in the name of the Earth when Marvin the Martian lands on the same planet (in a ship called the "Martian Maggot") and claims it in the name of Mars. The stage is set for a battle of wits (or lack thereof) between the two cartoon stars.
