A recent college graduate that has moved in with her girlfriend after over a year of dating. She's trying to gain her footing in the world, being unsure of what to do next with her college degree in entomology. It's tough being in several new situations all at once, so Mable does her best to simply take things as they come.

Mable is a person of interest to the crows due to her job's location having full windows in a more remote area of Springfield, so they can clearly see that she stands behind a counter. When she isn't working, their interest lies in her relationship to her partner.
