Roz (voiced by Bob Peterson) is the bookkeeper of the Monsters, Inc. factory. She speaks with a very rough voice and has a slug-like body. Roz has green-brown skin and a bit of grey hair on the top of her head and wears a red sweater. Mike Wazowski, James P. Sullivan's assistant, tries to avoid getting in trouble with Roz mostly because, no matter how many times he tries to remind himself, he almost always forgets to file his paperwork. She is revealed to be Agent 001 of the Child Detection Agency.
Here is a classic dialogue between Roz and Mike Wazowski:
Mike: Good morning, Roz, my succulent little garden snail. And who will we be scaring today?
Roz: Wazowski! You didn't file your paperwork last night.
Mike: Oh, that darn paperwork! Wouldn't it be easier if it all just blew away?Roz: Don't let it happen again.
Mike: Yes, well, I'll try to be more careful next time.
Roz: I'm watching you, Wazowski. Always watching. Always.
Mike: Ooh, she's nuts.
