Pony from one of the futurama episodes. It had like 2 seconds of screen time or something.
Which was long enough for me!

Purple berry runs a blueberry themed store in canterlot. Blueberry pies, cakes, crumbles, pancakes, waffles, tea, teacups, etc. Purple berry also delivers in canterlot as well, and has a cart.

Is both male and female, transgender. Was born that way and loves who Berry is. Usually speaks in the third person instead of using pronouns, refers to self as Berries. Earth pony.
