Steetz is not her real name, but actually her street name, as she has a history of making up her names.
She is known for robbing stallions (and mares) looking for a good time, as she likes to pose as an “escort” looking for ponies to pay for her services. Once she get’s into their homes, she would then knock them out, and stal as much as she can.
She has a snarky and teasing personality. Fly-Bi is the only pony she actually considers herself to be friends with.
