It was fairly easy to make the frankenstuff/aqua duck. The frankestuffy was made because of a big explosion from a missil that missed its target and landed where joe the duck was. what I would do differently next time is try to get a group like Jayden and Nolan did and make a huge video with loto of frankenstuffys in it.
