Jabun

In The Wind Waker, Jabun (ジャブー, Jabuu) is a giant fish known as the Water Spirit who used to live at Greatfish Isle. He can only speak Ancient Hylian. Before Greatfish Isle was destroyed, he sensed Ganondorf coming and fled to a cave hidden in Outset Island. Knowing of his whereabouts and seeking the third pearl, the King of Red Lions and Link sailed to his new home. Although Jabun first hesitated to hand over Nayru's Pearl to one who had no connection to the Hero of Time, the Water Spirit ended up giving the final pearl to Link, leaving it up to the gods to test the true courage of the young hero.

Connections to Jabu-Jabu

 * It is possible that Jabun is Jabu-Jabu (or a descendant of Jabu-Jabu) whose name is now pronounced differently when spoken with the new language. The Japanese for Jabun is pronounced "Jabu" and the music played whilst meeting Jabun is a remix of the theme played Inside Jabu Jabu's Belly.
 * Because Jabu-Jabu was the guardian deity of the Zoras, some believe that he might have transformed them into Rito and named them after Ruto, the Princess of the Zoras. With gradual linguistic evolution over time, the new name of the tribe eventually became "Rito."

Trivia

 * The Prima Games guide for The Wind Waker says that Jabun was once known as Jabu-Jabu.
