Keep clicking the apple and try to reach your goal. When you reached the goal, check the shop for costumes. Also you have to get 1 more than your goal, otherwise the costume will still be locked. (e.g. you have to get 51 points instead of 50.) Please exit the shop after you do something in it because if you don't, the costume will still be locked even if you do more than what the goal says. :(
Thanks to my sister for her help
