I forgot to mention earlier, one last reason to believe the ducks weren't originally planned for Fix-It Felix, Jr. For the dust clouds Ralph makes only in the movie, it's a little neater: The cloud on the right is an exact mirror of the cloud on the left, while the cloud in the middle is whatever the previous graphic for the cloud on the left was (that is, it's one frame behind in the cycle of animation), though these different-sized cloud animation frames are not simple re-sizes of one another. If anyone's trying to copy these graphics for a movie-accurate game, remember that it turns into three smaller clouds at the very top, where the cloud on the right looks a lot like the cloud on the left, but again doesn't look perfectly identical. I was stepping through the movie some more, and I'm starting to think that to save time, the animators simply drew the whole dust cloud freehand and scanned it into game-size pixels, then zoomed it to a slightly different size and scanned it into pixels again, as the inner creases do expand and contract with the outer edges.
