The Marble Mover Challenge was a contest that Disney Channel Australia ran from December 25th, 2007 through January 25th, 2008. A commercial gave details on the contest and also served as a promotion for February 2008 launch of the series. A QuickTime movie of the commercial can be watched at the pictureDRIFT website by clicking on "QT MOV 6MB" above the description of the commercial.
Dan Povenmire and Jeff "Swampy" Marsh posted a YouTube video on May 2, 2008, congratulating the winners, which were from New Zealand. Dan and Jeff added in congratulations from Dr. Doofenshmirtz and Major Monogram, with Dan attempting to preserve the illusion that Dr. Doofenshmirtz is a separate person by covering his face.
The Marble Mover Contest and any submitted video entries are no longer available on the Disney Channel Australia website, with the exception of the "Terms and Conditions" for the contest.
