While on a mission in space, Dudley accidentally causes the most powerful T.U.F.F. super space laser to break into three pieces. Snaptrap wants the laser for himself so that he can pop all the corn in the world’s “corn belt” in order to raise the price of movie popcorn.
However, Snaptrap doesn’t realize that heating the “corn belt” will result in the Earth’s total destruction. The race is on for Dudley and Kitty to get all the pieces back before Snaptrap does. Source:
