The mystery vinylmation trade boxes are located in Frontierland (Westward Ho) and Tomorrowland (Store Command). There may be one more, but I forget right now. Anyway, one mystery box is a 3 row by 5 column box, numbered 1-15. The guest will pick a number and the CM will pull out the vinylmation behind it. Depending on what CM is helping you, they could make you trade for it, give you the option of keeping your original vinyl, or may give you another guess. If you do get another guess, the CM may make you trade for it, no matter what, or will give you the option of deciding to trade for it or to keep the original. Personally, I always give the guest 2 attempts and give them the option, after two guesses, to keep the original one. :) - BaseballMickey_CM  2788.6 #16 7:57PM
