Something nefarious is afloat in the depths of Bikini Bottom: King Neptunes crown has been stolen, and the prime suspect is Mr. Krabs, SpongeBobs boss at Mr. Krabs Krabby Patties. Despite the overwhelming evidence against Mr. Krabs -- not to mention having been turned down for a long-awaited promotion at the restaurant -- SpongeBob (voice of Tom Kenny) refuses to believe that his boss is responsible and teams up with his best friend, Patrick (voice of Bill Fagerbakke), on a mission to Shell City, where he hopes he can exonerate Mr. Krabs and return the crown to its rightful owner. Of course, this is no easy task; once outside the safety of Bikini Bottom, SpongeBob is faced with the overwhelming dangers of the sea, not the least of which being a cyclops that many believe to be responsible for the deaths of countless other unfortunate sea-creatures who ventured outside county lines. Among those who lent their vocal chords to the film include Scarlett Johansson, Jeffrey Tambor, and Alec Baldwin. ~ Tracie Cooper, All Movie Guide
