King Bubbles are enemies that appear in The Adventure of Link.
King Bubbles can be found only in the Great Palace. King Bubbles are basically bigger and stronger versions of the Bubble. Like the normal bubbles, they are capable of draining Link's health energy and magic power. After Link has slashed them several times, they split up into two smaller bubbles. King Bubbles do not reward any experience points upon defeat, but the smaller bubbles give normal experience.
