well i have heard this one, i dont know whether it is true but i might try it. when you are in don corneo's (i think thats how you spell it, correct me if im wrong plz) mansion for the first time, when you are dressed as a girl and all the guys go to jump you, i have heard if you speak to all of them and circle around the middle one about 20 times a small speech box comes up and says "hey cloud" and the game freezes.

thats only what i have heard, i dunno if it is true.
