The Abandoned Lobby is a floor where the player can explore a darkened lobby. It only spawns when the floor count is 1111 or just 1's afterwards in the elevator. Players are rewarded the Old Lobby badge when leaving the elevator on this floor.
The noticeboard displays code, which, when Base64 decoded, shows the Milo Murphy's Law theme song lyrics, and the clothes shop, Fanarts Room, Credits Room and Security Room are all removed. Every NPC in the lobby has been deleted, and the keypad beside ####### #### is no longer functional.
The server time board is gone, and Restricted Area's door is open, leading to the Shutdown Room Door which is also open. Inside, the Shutdown Button is non-working and the screen shows Base64 "Never Gonna Give You Up".
The entrance/exit door is open, and you can go outside. This floor always starts at night. If you go outside, you can see Huggy Wuggy from Poppy Playtime. If you touch him, you will get a jumpscare of his image.
