I was able to get the same FS RD, and she was surrounded by Pinkies (probably 4 Pinkies to each RD) and have also found FS white music notes Celestia and Luna in the Wal*Mart here, but no AJ as of yet
I also haven't found FS Daisy Dreams, either, but when I do, you betcha I'll let everyone know!!
Oh! And as far as G4zillas go, I've found Twilight with the snap-on rainbow wings, and, oof course, Year of the Pinkie Pie Chinese calender pony, but that's it :/
