A woman Donut uses as her benchmark of attractiveness when grilling the primal about its girlfriend.
Jumping Jen-Jen exists in this chapter as a unit of measurement. Prefacing that she knows it is not very feminist but that attraction matters in relationships, Princess Donut asks the primal how the young lady in its metaphor compares to, say, Jumping Jen-Jen.
The answer she gets is Orren's dry observation that the woman looks like Agatha, which sends the conversation straight into the outburst that cracks the desk. Nothing further is established about Jen-Jen herself.
Donut's throwaway standard of beauty in the metaphor interrogation.
