I need to rewatch it and look for blind bag crystal ponies, like sassaflash and mosley orange and royal riff... I remember seeing lots of wheat symbols...
also are all crystal ponies earth ponies!
I noticed there are no unicorns or pegasi (I hesitate to say they are all earth ponies because I think crystal ponies are their own type
) and besides the library pony I only saw only 2 types of cutie marks for each gender:
Males have either a bow and arrow or a rook (is what I think it's supposed to be)
Females have a fleur de lis or (I think that is) a laurel leaf.
Many of the crystal blind bags have been seen as background/secondary characters already in other places in Equestria though.
Oh and yes we need those toys majorly! I don't even care where the glitter is, if it mixed in the plastic, on the outside like the Pinkie and AJ protos ,or if they are just shimmery/translucent like the RD, Fluttershy & Rarity prototypes looked. Gimme crystal ponies!!
