Wind Whistler, especially if they brought back Sarah Partridge.
Picture it: Wind Whistler and Twilight getting into a super-scientific discussion, throwing out all these big, technical terms, while everyone else looks on in utter confusion.
Yep, they used the G3 Minty in one of the big Canterlot gift sets. In fact, if anyone is sad they missed that set, it's BACK! Toys R Us has it for $30, for I think 7 Ponies. Since we spent just $20 to get Minty (the original set sold only through Costo, and we didn't have a membership), lemme tell ya, that's a steal!
I'm tempted to get another set, just so I have the Princesses in all their clothes.
I want baby ponies who don't sound like they're voiced by actual random 2 year olds. Or that jsut lose their annoying bits. Like Quackers. And Sea Ponies.
Ooo. Twinkle Eyed Ponies would be FANTASTIC! Imagine the toy line that would come out with them.... Flutters and Sea Ponies would be interesting. I hope they could make the Flutter Ponies a little less snobby. Specifically QUEEN ROSEDUST. Bring back Russi Taylor (Morning Glory)!
Fun fact: Russi Taylor and her husband were once the voices for Micky & Minnie Mouse. Awww.
