Your character icon will change from Squall to either of the three female characters (they change at random). On this screen you can talk to them and you will be able to choose from many options. You can choose to listen to all the music, or watch all the movies, or you can even type in random numbers that can trigger battles throughout the game, or random add-ins, such as "Dummy", a Cactuar-looking cardboard box. It has 50 HP and can't attack you. You sometimes get random messages like "?Squall's ^$&" or "Squall's Quezacotl was blown away" even if it's not junctioned to him.

This picture was taken from the PC version of the game. Why I put it in here I don't know.
