- "Jabun can only speak Hylian, so hardly anyone understands a word he says."

- "Even after the land of Hyrule was sealed away, the guardian spirits of the three pearls of the goddesses remain. They are thought to be descended from Volvagia, the Deku Tree, and Jabu-Jabu, spirits that existed during the Era of the Hero of Time."
- — Hyrule Historia
After being released from his imprisonment, Ganondorf attacks Greatfish Isle in order to seize Nayru's Pearl and kill the Water Spirit. Jabun manages to escape, but Greatfish Isle is destroyed by Ganondorf's wicked magic. Jabun retreats to a shelter in a cave on Outset Island, and seals the cavern with a mighty stone doorway. During Ganondorf's Endless Night, Link obtains Bombs from Tetra's Pirate Ship and blasts open the doorway to the cave, finding Jabun inside. Lord Jabun speaks in ancient Hylian to the King of Red Lions, and during the Second Quest, Link can understand what Jabun is saying. Jabun questions the King of Red Lions about his search for a new hero and the descendant of Princess Zelda. The King of Red Lions assures Jabun that Link has the potential to live up to the reputation of the Hero of Time, so Jabun agrees to give them Nayru's Pearl, which he had housed inside the lantern atop his head. This is the only pearl Link obtains without first completing a dungeon.
Jabun is stated to be Lord Jabu-Jabu by Prima's Guide for The Wind Waker, meaning that he returned to the land of Hyrule following the Hero of Time's departure to the past and that he survived the Great Flood, taking on the name Jabun once the Great Sea was formed. The credibility of the guide is disputed, however, since Prima is often inaccurate in their information on the series, and since this theory has not been confirmed by Nintendo. Jabun's theme sounds very similar to the background music from Inside Jabu-Jabu's Belly, which may imply a relationship between them.
It can be very likely Jabun IS in fact Jabu-Jabu, as the suffix "n" is added to nicknames of endearment in Japanese culture, meaning Jabun is short for Jabu-Jabu.
Jabun also speaks Ancient Hylian, also supporting this.
