Key Master

Key Masters are enemies in Spirit Tracks. They appear in some dungeons whenever Link tries to carry the Boss Key to the boss door. Link must take a certain path or the Key Master will appear from the floor and chase Link. If the Key Master retrieves the key from Link, they disappear into the floor and the key will reappear at its original location, forcing the player to try again.

Their appearance in this game is similar to the Floormasters from Wind Waker and Ocarina of Time and Zant's Hands from Twilight Princess. They appear from the floor through black portals, and have eyes on their palms. They "walk" on their fingers.
