After several failed attempts to put her back, Randall sends the door back into the factory&door vault and Sulley conceals her and takes her out of the factory. He interrupts Mike&date with his girlfriend, Celia, at a sushi restaurant, and chaos erupts when the child is discovered. Sulley and Mike manage to escape with the child before the Child Detection Agency (CDA) quarantines the restaurant. They soon discover that she is not toxic after all; Sulley grows attached to her and calls her "Boo", while Mike is just anxious to be rid of her. The two smuggle her back into the factory disguised as a baby monster in an attempt to send her home. Randall discovers Boo...
