Looking in his book for Earth creatures and finding the Tasmanian devil, Marvin the Martian gets the idea of capturing Taz for his zoo. He heads to Earth, beams Taz up into his flying saucer, and takes Taz to his Martian zoo. Taz escapes.
After making his way back to Earth, Taz returns to Mars and visits Marvin's house to find and defeat him.
After defeating Marvin, Taz steals a space ship and steers it to Earth. The game ends when the devil eats a pile of fruit on the way home and went away spinning all the way.
