Instant Martians

Instant Martians are the names given to Martian's that Marvin the Martian grew from seeds in Hare-Way to the Stars, and water's. He sent them after bugs, but they were all outsmarted by him. Prior to this short, aliens that looked exactly like them appeared in Jumpin' Jupiter. Younger versions of them appear in Duck Dodgers. One of them also made a very brief cameo appearance in Looney Tunes: Back in Action sleeping on the job of guarding the ship and failing to notice Bugs and Daffy got it. They reappear in The Looney Tunes Show during Marvin's music video "I'm a Martian". In this short video, in addition to one being a DJ and one a hippie guitarist, there are also very attractive female ones seen dancing.
