Chalooby is a janitor that works at Monsters, Inc., performing tasks such as mopping the floor. However, since he oozes slime when he moves, this often makes his job difficult. He is a slug-like monster with five eyes of varying sizes.
Chalooby had finished mopping the floor one day, and after giving a nod of approval to the clean floor, he began to move away, leaving slime behind him in the process. During this, he was greeted by Mike Wazowski, and he responded with a quiet screech.
