Knowledge can be dangerous o.o
There are a lot of Mexicans...
In the personal, my Mexican army has more than 250 members, and I've find out a lot of small differences, the syze, position and arrangement of the symbol, eye color (mostly blue and purple), type of hair (straight or curly).
Lili Ledy (as far as I know) there are only 12, Blossom, Cotton Candy, Butterscotch, Minty, Blue Belle and Snuzzle. Both flat feet and concave feet (I'm not sure about hair colors).
Auriken has a bigger quantity, and have some really amazing ones (the alt. color Sundae Best!!), new poses (Cherries Jubilee pose Blossom, pegasus Baby Blossom), and the Princes!
In the personal my all-time favorite Mexicans are Starflower and Pinwheel with yellow hair =D
