What clock in the gizmo place do find a postcard & the one in the hotel..

You dont get post cards from the hotel clock (you get some items if you do that task though), the clock which you need is in the gizmo shop, as you enter and turn left head for the door on the other side, stop however and turn right to face the wall there is a small clock that has stoped at 6:54. To get the two post cards jump on the moving platforms and on to the wall above, step on all the large button things along the wall panel. now you can go down and look at the clock again at obatain the two cards.
To beat Cloud equip the strongest key chain you have, in this battle you'll have to do most if not all of the work yourself, since donald and goofy wont get any hits in while hes lunging forward really fast with his sword, which means its also not a good idea to give them potions and ethers they love to use them anyway and during this match they be gone within five seconds. It's good to have dodge roll equiped and glide if you have it. Now, run up to cloud and he will statpeting towards you with his sword dodge roll these but stay next to him, eventually he will stop lunging and jump into the air and slice down, try and Make sure he doesnt connect, this is your chance to attack him, swipe away and he will fight back by swinging his sword you can deflect his sword which leaves him open to attack, so do so. repeat this untill cloud gets angry and starts gliding around with his wing, in this case just continually dodge roll, dont stop untill he lands back on his feet. if you get hurt glide away(or run) and let donald and goofy take the damage while you heal your self in the corner. thats about it, have fun!.
