Kyameron

Kyameron are enemies from found in the Swamp Palace.

Characteristics and Weaknesses
Kyameron are bubble-like enemies that appear out of the shallow water when Link walks by, and once they have completely formed, they will bounce around the room until they hit their target. In case that they do not hit Link, they will disappear into nothingness. The only way to defeat a Kyameron and prevent its regeneration is to freeze it and then hit it with the Hammer.

In the additional Palace of the Four Sword dungeon for the Game Boy Advance version of A Link to the Past, after all the Bari that surround him have been destroyed, the Orange Arrghus boss is able to summon swarms of Kyameron.
