The second DLC chapter is titled "The Hideaway" and features the Kid and the Nomes.[6] It starts with the Kid escaping from the paper he is wrapped in, which is ascending on a hook towards the Kitchen, and he falls to a new level of the Maw. With the help of the Nomes that he finds along the way, he finds an engine room where the Nomes are brought to throw coal in the furnace. One of the rooms in the area has a similar viewing machine as in the Lair, where the Kid can see places where Six has been, and he even witnesses Six herself treading through the sea of shoes. During this campaign, the Kid also encounters the Janitor. After finding all the Nomes and bringing them to the engine room to help power up the furnace, the large bucket elevator in the back of the engine room becomes fully functional, ultimately lifting the Kid up to where the Nomes are gathered, presumably the "Hideaway". The shadows indicate that the Nomes actually are or have been children. Then, after leaving through a crack in the wall, the Kid eventually finds himself on a rising platform, which is the top of an elevator where the Lady is standing.
