Documents' Key

The Documents' Key is an item in Dream Game.

Overview
The "Documents' Key" is an item that's found frozen in an iceberg at Ten-Mou. In order to break the part of the iceberg that's holding the key, you have to throw 4 ApocBR cans at a specific spot of the iceberg then use the Delete Hammer at the said specific spot which will break the ice in half, dropping the Documents' Key onto the floor allowing you to pick it up as an item in your inventory.

Despite the name of the item, this item isn't even used for the Documents Room, as Nash later on finds out that the key wasn't even made for the keyhole. This leads into other lore speculations as to what this key's actual usage is.

Documents Room Interaction
Upon using this key on the Documents Room located in Ten Mou 's town, a special interaction will play out with Nash saying: "Nash: The key is not working!! or am I just bad at this somehow?"

"Nash: Ugh whatever, I'll just break the door with the hammer." You are then able to break, not just the lock, but the ENTIRE DOOR causing it to drop into multiple pieces like a smashed biscuit. Renting the key obsolete for it's purpose...

Trivia

 * Although Nash breaks the Documents Room's door with the Delete Hammer as a substitute solution for the key not fitting, you still can't break the door without the key as the key is vital for the Documents Room interaction.
 * It is unknown whether or not if the key has any other usage outside of the Documents Room interaction. However, seeing as Nash mentions that the key doesn't work on the door, it implies heavily that the key was likely made for a different door.

Bugs / Troubleshooting

 * At the moment, there's a bug with the Documents' Key obtainment method where the key phases through the ground after you break open the ice. This is because the key drops on the ground as a tool and since the key is only one mesh which is the handle of the tool, the handle doesn't have any collision in order to fix awkward collisions with the key when the player is holding it.
 * Solution: In order to solve this, after you break open the ice block you must quickly grab the key before it phases through the floor.
