A lot of children may not know that Monsters, Inc. features a toddler named Boo. The movie is based on the true story of a little girl who walks into a closet and latches on to James P. Sullivan’s hand. Since children are considered toxic for monsters, the monsters do not like them. The monsters attack and scare the kids, so the little girl decides to jump out of her closet and scare them.
The first movie featured the famous scarer Boo, who is a gray, spider-like monster with long legs and arms. He is the company president of Monsters, Inc., and is a close friend of Sulley and Mike. During the film, Boo was filmed to be a scarer and used laser vision to blow a car and exaggeratedly flew over him. The two boys quickly learn to adapt to each other, though their real names are still a mystery.
The name of Boo is not mentioned in the movie, but it is implied that he will be renamed after meeting with Sulley at the end. The film’s executive producer, Bobs Gannaway, says that Boo will never return, but the film did hint that Boo’s name may have been revealed after his visit. While the character’s name is not explicitly mentioned in the film, many fans believe it is an homage to a fictional character.
