Helen

4th Grade Female Cat is an unnamed fourth grader. She has always been used as a background character and has yet to have a speaking role. Her personality is unknown and her most significant role was in the episode D.W. Bossy Boots when she attended Emily's birthday party. The relationship between her and Emily is a mystery though it's most likely she was just invited. She does hang out with mostly fourth graders, but is seen hanging out with third graders. She is also in the same fourth grade class as Prunella as seen in the episode Prunella's Special Edition. She is most of the time seen either in the hallways or at lunch. Most of the time when she appears she's often with her best friend who is also an unnamed fourth grader. They most likely also went to the same kindergarten class as seen in a picture in the episode Brain's Shocking Secret and is probably where they first met each other.
