Take out the trash; eat your broccoli -- who needs moms, anyway? Nine-year-old Milo finds out just how much he needs his mom when she's nabbed by Martians who plan to steal her mom-ness for their own young. "Mars Needs Moms" showcases Milo's quest to save his mom -- a wild adventure that involves stowing away on a spaceship, navigating an elaborate, multi-level planet and taking on the alien nation and their leader. With the help of a tech-savvy, underground earthman named Gribble and a rebel Martian girl called Ki, Milo just might find his way back to his mom -- in more ways than one.
