The Right Hall returns in Ultimate Custom Night as CAM 02. It takes the form of a long hallway directly to the right of the Office.
The Right Hall resembles the East Hall from the original Five Nights at Freddy's. It has monitors on the floor, the "Celebrate!" poster from the first game's office, posters of Freddy Fazbear, Bonnie and Spring Bonnie, the Paperpals from Freddy Fazbear's Pizzeria Simulator, shelves containing cleaning products and Mr. Hugs.
Circus Baby, Nightmare Mangle, and Nightmare Bonnie all traverse through this hallway as they approach the Office. They all share the same behavior, in that once they are seen on the Monitor, the player must quickly switch to the Prize Corner camera and purchase the respective plush of whichever animatronic is there. Each one of them will only appear once per night, though the order of their attacks varies.
Rockstar Chica can also enter this location, where she can enter the Office if the player is not careful. In order to impede her progress, the player must move the wet floor sign in the Office to the right side of the room.
Jack-O-Chica also appears in this hallway when the temperature increases too high in the Office. She can be stopped by closing both the left and right doors simultaneously, though this will be ineffective if the temperature exceeds 100 degrees.
