The Cobble Knights are four knights from Phantom Hourglass chosen to serve King Mutoh and protect the Cobble Kingdom. As of the current events that have happened in Phantom Hourglass, all of them have perished along with their king and kingdom. Link has the ability to speak with them, as he needs their guidance when he searches for the final Pure Metal, Aquanine.
