Field of Dreams

 Field of Dreams is an in-app purchase for Bad Piggies (free on the PC and formerly, NOOK versions) that is currently available for iOS, Android, and PC. It seems to be 2 Sandbox levels merged together as it has 40 star boxes. It also has a large number of every single part in the game, even ones that were not available in previous ones. The level was formerly included free on the NOOK (as in game purchases are not available), but was removed with the Flight in the Night/Road Hogs update. It has only 1 level.
