We were all curious about it yesterday, and it looks like they have finally popped up. Hasbro has some "official" names for our favorite background ponies. Obviously due to legal reasons, they couldn't use the fanon ones.
Lyra is above, and Berry Punch/Blues/Carrot Top can be found after the break.
Note: For the sake of not driving fanfiction archives everywhere insane, please keep using the fanon names for those! Or at least include that your "Heartstrings" in the story should be filed under Lyra.
