Twinmold

Giant Masked Insect: Twinmold is the boss of the Stone Tower Temple, the fourth and final dungeon in The Legend of Zelda: Majora's Mask. The boss battle is fought in what appears to be a huge, enclosed desert.

The Twinmold boss consists of two large, segmented worm-like creatures. On their heads are a pair of large pincers and three large eyes. On their tails is what appears to be a stinger. The slight difference in color of the two worms may indicate a difference in gender.

Story
Link unlocks the door to the boss room with a Big Key. Inside, he finds a portal in the floor. Jumping into it, Link is transported to what appears to be a pocket dimension; a huge desert filled with stone monuments. Shortly thereafter, the monstrous Twinmold appears, burrowing out from the ground.

Battle
The most common way to defeat Twinmold is to equip the Giant's Mask found earlier in the dungeon. The mask will increase Link's size until he is the size of the two worms. He can then strike their vulnerable heads or tails to damage them. After defeating one of the Twinmold, its body explodes, leaving its head embedded in the ground. After both heads have been defeated, the battle ends.

An alternate way to defeat Twinmold is to use arrows, bombs, or the Fierce Deity's Mask when the heads or tails come down close to to the ground. Due to Twinmold's immense size, the Fierce Deity's Mask is not an efficient method of killing Twinmold, as it is difficult to obtain a Z-target on them.

Interestingly, if Link strays too far from the center of the cheese, he will fall through the holes and be forced to fight his way back to the boss lair and repeat the battle.
