Of course, the most important thing fans want to know is if Boo is in Monsters as Work, along with Sulley and Mike. Boo is the young girl whose escape from her room and into the monster world in Monsters, Inc. causes most of the trouble that Mike and Sulley face.

In the end, she and Sulley share an affectionate relationship and it's adorable. But she won't be popping back in this time.

"Pete Docter [director of Monsters, Inc.] and I had a nice discussion about Boo,"  Executive producer Bobs Gannaway said at a press Q&A, according to Radio Times. "We both agreed the relationship between Boo and Sulley is so precious and so wonderful that we want to leave it to the world to have their own interpretation of how that relationship continued, and not define it."

But even though Boo isn't in Monsters at Work, it doesn't mean the show is any less ingrained in the universe that began with Monsters, Inc. The show takes place in the same setting and gives more insight into how things go once Sulley and Mike take over the company. It also explores how some monsters may not be ready for such a big change.
