"Duda dub baba!"
Sure it may not be as "fancy" and "developed" as something like Al Bhed (lol, as if wink ), but there are other little conlangs in the Squaresoft universe! In the underloved game Legend of Mana, there are little creatures called Dudbears that you encounter. In one part of the game you have to sell lamps to them, and can only do so by communicating in their language. It's very very simple, and not at all a complete conlang, but it's cute.
Here's a guide to it, with as much info as you ever get in the game: http://www.gamefaqs.com/console/psx/file/256525/7963
