Thanks be given to:
greseres for berry punch [link]

So this got pointed out to me from a non-brony mate that the two crescent moons i used in the background looks like a perfect circles logo... got to admit i see it to, but was made to be so. But Berry Punch, I get the her being a drunk jokes but I dont get how ruby pinch is her child? I mean in Sisterhooves Social they were shown to race with each other so...how is she her child again?

Also: All the images in this artwork belong to Hasbro and DHX Studios, lastly thanks to Lauren Faust for all her work on the show.
