Description[]

Original five keys.
Keys are several exclusive pieces included in all of the sets from the 2010 Atlantis Theme (excluding the impulse sets - 8072 Sea Jet and 8073 Manta Warrior). They are an important feature in the Atlantis theme, because only with all of them can you open the Portal of Atlantis. In 2011, a Purple Key must be found to release The Golden King.
Each one also includes a black picture of a certain undersea creature, such as a squid or crab and is often than not protected by the Atlantis Creatures.
