She also takes her jobs very seriously, to the point that she had to seriously deal with others who annoy her working, such as Mario. Karen appeared to be laid-back personality, evidently with her calm face. She’s a anthropomorphic cat with white fur and hair (with a bit of turquoise underneath her hair and on front of her ears), wearing yellow reading glasses matched with a Starbucks-like uniform with a light green T shirt and a average green cap and apron with her name tag. She made her first major role in SMG4: Mario Does His Laundry, working as a laundry aide in a laundromat. She made a cameo in SMG4: Mario Goes To The Zoo, where she was at the zoo being burned at the stake by the pig army. She would later send him and his tent to a garbage dump. She is then seen again trying to get Mario off the store for trying to camp outside of Sundays, but was kicked in the face. She gets annoyed by Mario sneaking around her and scared him away with her shotgun.
She made her debut in SMG4: The Mario Documentary, working as a barista at a local Starbucks.
