By my definition of 'cute' only moogles and cactaurs make the cut. Moogles have the advantage since there is a variety of designs of them, and I would have to say FFXII's version of them was the best. So yeah, moogles. I think cactaurs are hilarious, especially the versions of them where they are simply animated by a few frames, and 2D in a 3D game (if I recall correctly?)
