There are papers, sheets with pencils, and notebooks (not to be confused with actual collectible ones of the same name) found laying on desks inside the classrooms. The Player can see a stickman on the paper but it can't be for sure. The notebooks on the table cannot be picked up, unlike the other notebooks that the Player need to collect.
Inside the Principal's Office and few Faculty Rooms are earth globes. The size of the globes vary, some are a normal size but in some rooms, the globes are giant and seem to be clipping through the floor.
In the Cafeteria, there are multiple restaurant-based lunch meals on every table. The tray seems to have a drink and some bread or a burger inside of what looks like some tin foil.
In Baldi's Office, the player can find a banana above Baldi's desk. Not much is known about this banana or why it is in Baldi's Office.
