Roma

Roma is the placeholder name of a female Earth pony with a cream-yellow coat, two-tone brown mane, blue-green eyes, and a cutie mark of three tomatoes. She is unnamed in the show, credited only as "Vendor" in the closing credits of One Bad Apple and referred to as "MARKET SALESPONY" in the My Little Pony guidebook The Elements of Harmony.

Design
Roma has a similar color scheme to Fine Line, and she shares her coat and eye colors with Sweetie Drops, Press Pass, "Paisley Pastel", S04E20 Unnamed Earth Mare #1, S05E21 Unnamed Earth Mare #1, and "Hazel Harvest". Without her hat, Roma shares her mane style with Mayor Mare, and she also resembles S02E17 Unnamed Earth Mare #1.

Depiction in the series
Roma first appears in the season two episode Putting Your Hoof Down operating a tomato stand at the Ponyville marketplace. She sells three tomatoes to Fluttershy for two bits, the cost having gone up from one bit the previous week, but Pinkie Pie tricks her into selling the tomatoes for half the price.

In the season three episode One Bad Apple, Roma sells carrot crêpes at the Summer Harvest Parade. In the season four episode Trade Ya!, Roma operates a stand again at the Rainbow Falls Traders Exchange. Here, she sometimes appears without a hat.

Merchandise
Roma appears on the official season two poster and other second-party merchandise that depict the same. Page 31 of Little, Brown's My Little Pony Friendship is Magic official guidebook My Little Pony: The Elements of Harmony lists her as simply "MARKET SALESPONY".
