The Mayor of Ponyville. She doesn't seem to have an official name but I've seen folks calling her "Mayor Mare". She apparently turns up in some fan fics as "Vanilla Rose" or "Vanilla Latte".
I wasn't sure what I felt like doing today and in the end, a straight pony drawing won out over more animating Rainbow Dash. I'm sure she'll be furious - she hates losing - or so I hear
