It would make more sense if cloning was a Gungan speciality (most of them look the same for some reason).

Jar Jar even claims to have "A grand army".

The Kamino cloning centre seems to be mostly underwater, it could be reworked that they are using Gungan methods to produce the army for the Republic.

Heck, Jar Jar could be a failed clone explaining why his body is so uncoordinated.

It could even explain that bizarre power station that Maul fights the Jedi in (though in my take it's moved to the Federation control ship).

I'm trying to wipe out the Gungans in my own way... lol In all reality that ground battle is totally unnecessary and stupid... When you want both stupid armies to die then maybe they should just go away overall. I think it'd be better if the droids had taken over the city which they have and thus to free Theed they have destroy the droid control ship... thus skipping the ground battle and skipping one less ending.

Oh and the thought of Cloning Gungans... I thought we were trying to make Episode 1 BETTER. ;)
