Instant Martians are the names given to Martians that Marvin the Martian grew from seeds in "Hare-Way To The Stars". He sent them after Bugs, but they were 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 re-appear 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 Martians seen dancing. They next appeared in another music video "Be Polite". They later appear living in Marvin's house on Mars in The Looney Tunes Show. They also appear in Looney Tunes: Rabbits Run, when they take off the disguise of Cecil Turtle's goons.
