Many doors stored away in the warehouse

The Door Warehouse is home to a storage of millions of doors used by Monsters, Inc. in the movie Monsters, Inc. The doors are all transported to and from the Scare Floors via a network of overhead conveyor belts arranged like rollercoaster tracks. Mike, Sulley and Boo are seen traveling through the warehouse to get to Boo's door and escape Randall Boggs.


  • Pixar created all the doors in the warehouse from different combinations of 26 paint colors, 12 styles, 8 wood colors, 10 decals, 6 door knobs and 3 hardware types. This can create a maximum of 449,280 possible combinations.[1]
  • This is one of the most dangerous things to ride on due to doors lacking safety and can fall to their deaths.
  • Strangely, no humans entered the Monster World when all the doors in the warehouse were activated.
    • It is possible that the doors are designed to only open for monsters, but there is still chance that a human may accidentally enter the Monster World if a door was left open.
