From the announcement:
This lost story is a stand-alone adventure for Stuffed Fables that can be inserted between chapters 3 and 4 if players are enjoying Stuffed Fables as a campaign. This exciting story sees the Stuffies battling on the streets of their town with the dreaded Dollmaker and his newest contraption! You can download Lost Story #1 at the link below, along with a page for the special Car tokens attached at the end. We reccomend priting this Lost Story out on 11x17 Cardstock paper, front and back. This will allow you to either have the book cut down or cut it out youself. If you'd like there is also space on the edge of each page to accompany a spiral binding. We do not reccomend that you try to unwind and add this chapter to the main Stuffed Fables adventure book, as the spiral there is not designed to take on a wider book, and removing the spiral could damage it or your adventure book.
