Monsters Inc 3D Release date: 22 December 2012. Monsters Inc 3D takes place in a parallel world, in the city of Monstropolis, who is inhabited by monsters and powered by the screams of children in the human world.
At the Monsters Inc. factory, employees called Scarers venture into children`s bedrooms to scare them and collect their screams, using closet doors as portals.
This is considered a dangerous task since the monsters believe children to be toxic and touching them would be fatal.
However, production is falling as children are becoming harder to scare.
