[Shy Violet]

Earth: Sweet Tooth
Unicorn: Gusty
Pegasus: So Soft Heart Throb
Sea Pony: Sea Mist
Flutter Pony: Lily

[flutterscotch]

Earth Pony-Applejack
Unicorn-Twilight
Pegasus-Firefly
Sea Pony-Baby Tiny Bubbles
Flutter Pony-Honeysuckle
Winger-Glow
Alicorn-Princess Luna/Princess Celestia.  The weird creepy Princess Luna with the evil expression from 2011 that came with the equally weird non-brushable Celestia. But I also bought the Canterlot Castle the same day and swapped their heads.  Which I then gave to a friend once better versions of Luna came out. In retrospect it was kind of a dumb decision.
Merpony-N/A, I still don't have any.
