Planet 51:Killer Klowns from Outer Space

When the gang see a comet crash outside the town of Glipforg, they investigate and discover a pack of murderous aliens who look very much like circus clowns. They try to warn the local authorities, but everyone assumes their story is a prank. Meanwhile, the clowns set about kidnapping as many female Disney characters they can. It's not until they kidnap Cinderella, Pocahontas and Neera, that Chuck, Grawl, Lem and half of the Disney Princesses all decide it's up to them to stop the clowns and save all the women.
