Janie Penn is Laney's great grandmother. She was in the circus because she had a mustache. She appeared in War and Peaceville via a picture and a flashback.
Janie looks like Laney only she has wavier hair and a mustache. She wears a black dress and a black sun hat with a flower on it.
- The way Janie has a mustache, may be a reference to a running gag on the show where everybody mistakes Laney for a guy.
- In It's in the Card, where Grojband had broken up, Corey makes stuffed copies of his friends. He refers Laney's one as "Janey".
