What happens when you get all the postcards on kingdom hearts?

Answer 1

I don't really remember what specific item you get after you've retrieved all 10 postcards, but I can tell you where to find them:

1. Use Blue Trinity Mark in 1st District of Traverse Town near the cafe

2. In blue safe near the door to the 2nd District (you can't get it until after you have Donald and Goofy in your party)

3. On the roof of the Accessory Shop (wait until you have the High Jump ability because it makes things easier)

4. Hit the fan in the Item Shop

5. Synthesis Shop - examine the poster on the left side of the fireplace

6. 2nd District - in the chest on the awning of "Boots & Shoes"

7. Gepetto's House - 1st District - check the shelf in the back left corner

8. 2nd District - Gizmo Shop - step on the three square switches then check the clock (you must use Thunder on the cord in the 3rd District before doing this)

9. 2nd District - Gizmo Shop - step on the three square switches then check the clock (you must use Thunder on the cord in the 3rd District before doing this)

10. 2nd District - climb the ladder behind the Gizmo Shop - jump across the rooftops until you find the window entrance to the 3rd District - the Postcard is hidden in the corner to your right

Answer 2

There are 10 postcards in all and every single one is found in Traverse Town. They're locations are: 1. Attack the fan in the item shop 2. On the roof of the Accessory Shop 3. On the awning in front of the "Boots and Shoes" store in the Second District 4. Use the blue Trinity Mark near the Item Shop in the First District 5. After meeting Leon, open the blue safe in the First District, behind the Accessory Shop 6&7. Cast Thunder on the exposed wires in the Third District. In the Gizmo Shop, step on the three buttons scattered across the top section of the room. Then examine the clock near the middle of the Gizmo Shop to get two Postcards 8. After defeating the Guard Armor, climb the ladder outside the Gizmo Shop to the top of the Second District. Jump from roof to roof, and hop through the upper entrance to reach the Third District. Use the target lock feature to find a postcard in the corner 9. Use the green Trinity Mark inside the Accessory Shop, then check the piece of paper on the wall inside the Item Workshop 10. Check the small pot on the shelf in the corner of Geppetto's House By mailing these postcards in the mailbox (which apparently has a tongue :l ) you can get a cottage, Mythril Shard, Mega-Potion, Mega-Ether, Mythril, Elixir, Megalixir, Orichalcum, Defense Up, Power Up.
