Puzzle Key

are items in SS undefined.

Location and Uses
Puzzle Keys are found in Treasure Chests inside all dungeons aside from the Sky Keep. They are used to unlock the door leading to the dungeon's Boss. In order to unlock a door, Puzzle Keys must be rotated into an orientation that will allow it to fit into the shape of the key slot by using the Wii Remote. Doing so is often a small puzzle, requiring multiple rotations to find the correct placement.
