I made a new pony fan character just cuz I wanted. Chardonnay is the name of a wine, and a city from France. And Berry it's here since she is a similarly themed pony, and they both have cutie marks with grapes.
Sounds like Chardonnay and Berry Punch would make a good team. Berry Punch can show Chardonnay how things work around Ponyville, while Chardonnay teaches Berry Punch in turn about the various types of Fancy (i.e. French) wines and how to distinguish between them, and things like that.
