Bowser Junior, the young heir to the Koopa throne, shows his relationship with his siblings and father in this little tale of what goes on behind the scenes of Bowser Castle. When he overhears his father and Kamek hopelessly trying to make plans to conquer the Mushroom Kingdom, his Koopa cleverness shows as he butts in and shoots an idea. Bowser and Kamek consider it and send it into action. Will this seemingly foolproof plan succeed at long last? Or will these Koopas be sent back to the drawing board once again?
