Inside Jabu-Jabu's Belly

Inside Jabu-Jabu's Belly is the third dungeon in Ocarina of Time and is set inside Lord Jabu-Jabu's body. To enter, Link must place a fish in front of him, causing him to open his mouth and suck both the fish and Link inside. Shortly thereafter, Link discovers Princess Ruto and is commanded to help her locate the final Spiritual Stone, the Zora's Sapphire. Along the way, he finds the Boomerang, which he can use to fight not only the normal enemies within the dungeon, including Biri, Tailpasaran, and parasitic tentacles, but also Barinade, the boss. Link will receive a Heart Container and the third Spiritual Stone as a reward.
