Which scare-floor designation does Sulley work on in Monsters, Inc.?

Sulley works on Scare Floor F in Monsters, Inc. The designation identifies the large operational floor where monsters enter children’s bedrooms through closet doors and perform scare assignments.

At the beginning of the film, Sulley is an outstanding scarer and is competing with Randall Boggs for performance records. His normal routine changes when a human child, later nicknamed Boo, accidentally follows him back through a door.

The scare floor is one of the film’s major visual settings. It contains rows of door portals, moving equipment, employees, and supervisors, allowing Pixar to show the company as a busy industrial workplace rather than a simple haunted-house setting.

Viewers sometimes remember the floor only as the “scare floor” and miss the letter designation shown in the film. The letter is F, while other floors and work areas appear as part of the company’s larger building. The floor’s operations also connect the workplace comedy to the film’s central conflict over scream extraction.
