A do-it-yourself activity/storybook about the story of Jam. Jam was the most special out of all the Potter family, in fact Jam was the most special girl in all of Four Corners. Because you see in Four Corners, people didn't look like people, they looked like squares. Nobody knew why, that's just the way it was. But Jam was special, Jam wasn't shaped like a square. Jam was shaped like a circle.
