Lord Jabu-Jabu
Little is known about Lord Jabu-Jabu. In Ocarina of Time, he resides in Zora's Fountain, a sacred lake behind Zora's Domain, where he is worshipped by the Zoras and acts as a guardian deity similar to the Great Deku Tree. He is very fond of fish, and has grown quite large due to frequent offerings by the Zora. Young Link must feed Lord Jabu-Jabu a fish in order to gain entrance to his belly, so that he may save Princess Ruto, who had entered in search of her mother's stone, the Zora's Sapphire. To rescue Princess Ruto and get the Sapphire, Link must destroy Barinade, a parasitic electric anemone living inside Lord Jabu-Jabu's belly.
In Oracle of Ages, Jabu-Jabu once again lives among the Zoras; only this time, they live under the sea.
Jabu-Jabu has been compared to the Wind Fish from Link's Awakening, though it is a large fish and the Wind Fish is a winged, baleen whale.It also shares strong similarites with Jabun in The Wind Waker; not only are they both large round fish, but Jabun's theme music is a remix of the dungeon theme for Inside Jabu-Jabu's Belly.
