Plot
The plot is currently unknown.

Why It Was Cancelled

 * The first movie, while it received positive reviews, did not do well at the box office internationally (most notably in France and Japan) to earn a sequel.
 * DreamWorks did not have any plans to produce any future movie-genre parodies like Shark Tale, Monsters vs. Aliens (the previous film), and Megamind after former CEO of DreamWorks Animation Jeffrey Katzenberg stated that those films did not do well internationally.
 * The Nickelodeon show was a failure.

Result

 * The sequel was permanently cancelled.
 * Monsters Vs. Aliens is a standalone film.
