A young Mike Wazowski visits the Monsters Inc. factory on a class field trip to learn about how “scarers” harness human children’s screams for energy to power the monster world. He secretly follows a scarer through a door to the human world to watch him work; the scarer is concerned by Mike’s recklessness but impressed by his stealth, and gives him his Monsters University cap. Years later, Mike enrolls in MU’s scaring program and Randall “Randy” Boggs is assigned as his roommate. On the first day of class, Abigail Hardscrabble, the dean of the scaring program and president of MU, warns that students who fail the first semester’s final exam will leave the program.
