This here is Tangy Top, a pink unicorn mare with a green mane and tail, and her mane is designed like a dallop of whipped cream on a sundae. She's a young mare but very fat, almost immobile. Her belly, however, is a status symbol to her, as is her equally-massive posterior, but she's not like upper-crust or too "high society" in terms of attitude.
As explained by her requester, she's a bit of a business-minded mare and takes her job pretty seriously. She likes to relax with music, or a good buffet, and she's never very far away from both. Tangy grew up in the candy/confectionary business and supplies bakeries, candy stores and even Sugar Cube Corner with all they need to make the best treats ponies can buy. Her great-great grandmother was Cotton Top, who changed her name to Cotton Candy Top after learning how to magically grow cotton candy plants(and promptly gaining upwards of several hundred pounds.) Today, Tangy carries on the family business for her growing stores as a growing representative.
She's a warm mare but can be a bit dramatic at times, and has plans to open new confectionary stores in the Canterlot High universe, just as soon as they find a mirror large enough for her to fit through. She also has her own personalized train, which she pretty much has to as the normal ones can't accommodate her large frame. She was originally born in Detrot and tries to visit often though she has to travel. She's interested in stallions and is a bit of a sucker for artists and musicians, secretly is afraid of crawly bugs and pests because it can take a long time for her to notice if something is crawling on her.
Despite her large size, she likes miniatures and small things that usually further emphasize her gravid form and shape. She's always very careful not to accidentally smoosh supplies or deliveries with her bulk, though that can be a challenge. She has a new dress for herself made every year that she showcases while she's out representing her company, Sweet Top Sweet Shops. Can't resist cake, donuts or ice cream, especially when mixed together and refuses to eat just about any food not served at the proper temperature. Currently dating Basil Bastille, a stallion chef who is also large but not quite as big as her, who enjoys keeping her well-fed.
