The Legend of Zelda: The Wind Waker/Bosses/Molgera

Molgera is a huge worm creature that is the fourth boss that Link faces in The Legend of Zelda: The Wind Waker.

Encounter
When Link arrives in the chamber where Makar is supposed to pray, the room fills with sand, obscuring the Hylian symbol on the floor and making an arena for the boss.

The Battle
Its attacks are varied, ranging from a jumping and diving attack to spawning small versions of itself.

Molgera's only weakness is his tongue, which has an orb at the end of it. This orb contains Molgera's life force. The orb cannot be hurt using normal methods (i.e. Bombs, Arrows, and the like.) However, L-targeting can be used to lock on to Molgera's tongue, then Link can use the Hookshot to pull its tongue closer to hack at with the Master Sword. If Link gets too close to Molgera, it eats him and then spits him out. After dealing a sufficient amount of damage to it, it will start to spawn minions. These mini-Molgeras deal a small amount of damage, but can get in the way while Link is trying to grapple Molgera's tongue. Molgera will sometimes fly out of the ground, and come back down, doing major damage if it lands on Link.
