Ive seen some of them, but for some reason ive done all haileys levels to lvl 16 and found all the poster girls. Yet i still dont have all these levels unlocked. Ive also done annies tutorial level and 1st stage along with finding the red gem. I still havent gotten the stages past the 1st proper stage for annie. If you can please let me know why
