The Legend of Zelda: Skyward Sword/Out of Bound Objects

Unused Chests
The game has a small handful of chests out of bounds. These can be reached and opened with codes.


 * Outside Karane's room. From the center of the room, it's after the wall towards the bed. It contains a Piece of Heart.
 * Outside The Lumpy Pumpkin's main hall. It can be seen if the player walks into the dresser and keeps going; it's on the right side of the map. It also contains a Piece of Heart.
 * Outside the Fire Dragon room's walls. From the platform where you talk to the Dragon, if you go forward and a bit to the left, there will be a poorly made room with the chest; it's on the top-right of the map. It contains the Goddess' Harp, but no text displays.

A video of the latter two treasure chests can be seen here.

In addition to those unused usable chests, there's a deactivated Goddess Cube chest inside the geometry of the Bazaar, a bit near its top, from the outdoors of Skyloft.

Unused Bird Statues
There are a few out of bounds bird statues, too. They also need codes to reach them. These include:


 * Outside the Sealed Temple, there is an out of bounds statue. Going to the sky makes you go to Hylia's Realm.


 * Outside the river part of Lake Floria there is some chests out of bounds along with a save statue. Going to the sky freezes the game.

Unused Doors
There are a few unused doors out of bounds in the Sealed Grounds/Hylia's Realm. They are:


 * In the entrance to Faron Woods, there is a door where the Sealed Temple's front entrance is. Going in it will send you to the Sealed Grounds.


 * In Hylia's Realm, if you go through the wall leading inside the Temple and go behind a small corridor behind a small door, you will see another door. Going inside will transport you to the same place, but with a few minor changes. Link does not make any sounds. Whenever you land from a jump, a Bokoblin will scream, but there are none at the time.
