Fin Fang Foom is found in Sakaar. He needs you to interview people around the cities for ideas to use with his company (which you helped him form in the first game). In order to get access to Defying Conventions, you need to help Howard the Duck in Manhattan and Forbush Man in the swamp area. Defying Conventions is found in front of the Timely Comics HQ. FFF costs 500,000 studs.
