Pixar's Canceled Monsters Inc. Sequel Had a Gut-Wrenching Ending

The story details surrounding the canceled Monsters, Inc. sequel suggests that the planned Pixar movie would have been a tough one to accept.
Monsters, Inc. primarily followed Sulley (Goodman) and Mike (Crystal) as they worked at the titular company that obtained energy from scaring human children. While living in Monstropolis, the pair were led to believe that children were dangerous creatures. That belief changed when a little girl named "Boo" snuck into the monster world, and Sulley vowed to get her back home safely. With the help of Mike, the pair avoid the Child Detection Agency (CDA) while essentially altering the perception when it comes to the relationship between the two very different worlds.
By the end of Monsters. Inc., Boo returned home and Sulley was made the CEO of the company after realizing that human laughter was more valuable than fear. Even though Boo's door was shredded, Mike managed to put the pieces together so that Sulley could visit the young girl one more time before the credits rolled. Shortly after, Circle 7 Animation was hired to start work on a sequel, and the concept art even made its way to YouTube as early as 2011. The sequel, said to be titled Monsters Inc. 2: Lost in Scaradise, was ultimately abandoned when Circle 7 Animation was shut down in 2006.
Plot Details For Monsters, Inc. 2: Lost In Scaradise
According to a plot breakdown (via Twitter), the canceled Monsters, Inc. sequel would have picked up over a year after the original movie when Boo's repaired door was put in the archive area. Due to their unique bond, Sulley was unable to let go of Boo so Mike set up a visit on Boo's birthday. When they arrived through the door, they find a snoring old woman in the room, leading them to set out in the human world to find Boo. In time, they realize that doors weren't connected t specific closets, but instead, they were gateways to particular people. Time moved a lot faster in Boo's world so, in reality, she was that elderly old woman hooked up to hospital machines. When Sulley and Mike realized this fact, they would have visited Boo again, and before she passed, the figure would've recognized her furry blue friend.
As touching as the reunion sounds, the story seems a bit dark for the entire focus of the movie. Pixar doesn't shy away from heart-wrenching material but this arc would have been a difficult reveal to accept. The original Monsters, Inc. sequel plans may have been scrapped, but a new follow-up of sorts will be releasing in the near future. Aside from Monsters University, Sulley and Mike's story is expanding with the Disney+ spinoff, Monsters at Work. Set to air in early 2021, the series will follow the two main characters not long after the events of the 2001 film. As of now, there are no indications that it will include heart-wrenching storylines.
