Sue Bob Murphy is the fourth worst kid in school.
Sue Bob's personality is not well defined because she has minimal appearances compared to the other bad kids. She is known to be a bully, stealing Cornchip Girl's lunch in "Don't Ask Me." She seems to be the calmest and most collected of the bad kids. While she does not seem to mind stealing or other stuff that makes her a frequent visitor to the principal's office, she seems to listen to people's stories a lot (or at least just Gretchen's). She also seems to have a little respect for Gretchen and a bit of resentment for Mikey.
She and Kurst the Worst appear to be good friends, probably due to being the only girls in their group.
Sue Bob has a narrow face with a light placement of freckles. In "Kurst the Not So Bad", she is revealed to have brown hair, blue jeans, gray sneakers, and a purple jersey with orange sleeves with a large orange number zero on its front.
- In "Don't Ask Me", she was voiced by Kath Soucie instead of the late Christine Cavanaugh.
- Sue Bob also made numerous cameos in two of the movies as well: Recess: School's Out and Recess: Taking the Fifth Grade. She does not have a speaking role in the latter, due to the fact that Christine Cavanaugh retired from voice acting.
