The series shares the same universe as Toy Story and Monsters, Inc.
Living Toys that live in a child's bedroom, only acting sentient when humans aren't around. Check!- As for Bumpy and Squishy, they were banished from the monster world for coming into contact with human objects (Bumpy and his appetite for socks, anyone?). The Closet Monster was sent to guard the area in case they or any other banished monsters tried to get back home.
- Since there are also anthropomorphic bugs, we can count A Bug's Life too.
- In respect of the The Pixar Theory, if you know of the theory, it is that the reason that the toys are alive is because of the magic of Wisps, so that is the reason that toys like Molly, Destructo, the Cute Dolls, ect, are alive while the toys are alive. humans do not see it, instead, if they saw the theory, they realized that the events of Monster Inc. are located in the distant future and that the doors where they go to the rooms of humans are portals of time, for which reason the monsters like Mr. Bumpy, Squishington and the Closet Monster are beings from the future, left in a time in the past
