The Kids are four children that attend Mrs. Nesbitt's kindergarten class. The group consists of a blue slug-like monster, a thin orange monster that resembles Rivera and Tony, a chubby green monster with four arms, and a thin, green monster with orange polka dots, three eyes, and a horn.
One day, Mrs. Nesbitt took her students on a class trip to Monsters, Inc., in order to learn about the company and the way it was run.
After James P. Sullivan realized the garbage cube he had retrieved from the trash compactor did not actually contain Boo, she, in her monster costume, ran by him, and towards Mrs. Nesbitt and the Kids, but was picked up by Sulley before she reached them. Mrs. Nesbitt politely asked Boo her name, to which she replied "Mike Wazowski!" During the conversation, the blue slug-like monster crawled up to Wazowski and bit his hand, causing him to yelp in pain. The incident made Boo laugh, which made the lights above them lose power, and Mrs. Nesbitt and the frightened kids fled the scene while Mike, Sulley and Boo ran in the opposite direction.
