One thing I would very much like to see is the underwater city of the Gungans turned into more of a hideout, or cloning facility. I hated that an elephant footed, floppy eared race of beings supposedly lived underwater......they do not resemble aquatic beings at all. If Ady is redoing much of the dialogue (or all of it) for the Gungans, then it should be very simple to bring across the idea that they live on land (and they actually DO spend more time on land in the film than they do underwater) (this would also aid in making it plausible that they also have trained many of the land based creatures on Naboo to be their pack animals and/or mounts). The underwater city should definitely be their secondary place of residence, or where they do their work, or a hideout of sorts.
