The Right Hall returns in Ultimate Custom Night mode, this time serving as a hallway for several of the animatronics to attack from.
The Right Hall mostly appears the same as in the first game, but with few decorations added to its design. Right there, there are multiple monitors stacked across each other. Also, it appears that the Foxy lamp from FNaF 3 makes a cameo hanging on the wall, alongside the trio of Paper Pals. Furthermore, Mr. Hugs is shown deactivated below the "CELEBRATE!" poster from the original game.
The Right Hall is a hallway where Circus Baby, Nightmare Bonnie, Nightmare Mangle, Jack O' Chica, Rockstar Chica, and Nightmare may attack. All of the animatronics who travel through the right hallway can't be stopped by the office door except for Nightmare. However, the player must use a sound cue to block him, and he can't be viewed on the Right Hall camera.
