Party Ponies

Kind of a sequel to this: [link]
I found out there's an old set of ponies called the Party Ponies! Of course I had to draw them with Pinkie Pie! No, Surprise was not part of them- she just fit. There was a seapony, too, but I didn't want to add it...
The ponies are, from left to right: Yum Yum, Best Wishes, Party Time, Baby Frosting, Surprise, and Pinkie Pie! All of their cutie marks except for Pinkie's are featured: Yum Yum's candies on the cake, Best Wishes' candles on the cake, Party Time's hats, Baby Frosting's cake, and Surprise's balloons <3
I imagine they're all old friends of Pinkie, who live in the same area as her parents, so she doesn't see them a lot.
