Key Master

Key Masters are a type of Master in the Zelda series. The Key Master is a hand shapped purple Master with an eye in its palm. So far they only have appeared in The Legend of Zelda: Spirit Tracks. Unlike other Masters who are trying to grab Link, the Key Master is only interested in the Boss Key he carries.

Behavior
Since it only targets the Boss Key of a dungeon, they naturally only appear in dungeons. They can be found in the Forest Temple, the Ocean Temple, and the Tower of Spirits. They only appear when Link stray from a certain path when carrying the Boss Key, they will start walking towards him on their fingers and will try to steal the Boss Key from him. If they manage to grab the Boss Key, they will sink into the floor and bring it back to its original location, forcing Link to try again.
