Catlein from the MLP Arena stumbled upon these in a Canadian Toys"R"Us, it is a 3-pack of the Photo Finish doll and the other 2 we saw during the NY Toy Fair, it seems like they form a band together called the Snapshots. The band has 3 members: Photo Finish, Pixel Pizzaz (yellow doll) and Violet Blurr (Green doll) The price you see is for the Giant Twilight Sparkle Brushable (the one on the right) We bring you more information later!

Many thanks again to Catlein from the MLP Arena for finding them!

EDIT: We know have the back of the box as well. The yellow doll is called Pixel Pizzaz and the green one Violet Blurr. You can find the picture of the back below the cut.
