FYI anyone downloading this there are issues with the centre box part where two of the big fish are just heads and the other two are just tails. This can be fixed with Pattern Maker by copying the bottom right quarter of the centre box (then deleting everything inside the box so you're not pasting over it), and pasting that part you copied, then pasting it another 3 times by rotating clockwise as necessary until the box is filled back up. You will then end up with the correct number of fishes all with one head and one tail!
