Giant Masked Insect: Twinmold (大型仮面虫ツインモルド Ōgata Kamenmushi Tsuinmorudo?, Giant Masked Insect: Twinmold) is the boss of 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 each one's head is a pair of large pincers and three large eyes. On their tails, they have what appear to be stingers. The difference in color of the two worms may indicate a difference in gender, like with the Gyorg Pair. Twinmold is one of the largest bosses in the series.
After exploring Stone Tower Temple, Link unlocks the door to the boss room with a Boss Key. This is the same room where he fought the Garo Master, but instead of a hole in the floor with sky below, he finds a portal in the floor. Jumping into it, Link is transported to a huge desert filled with stone monuments, some with depictions of Majora's Mask carved into them. Shortly thereafter, the monstrous Twinmold appears, burrowing out from the ground.
The easiest and most apparent way for Link to defeat Twinmold is to equip the Giant's Mask found earlier in the dungeon. Unlike other bosses, this boss is very hard to defeat using the Fierce Deity's Mask. The Giant's Mask will increase Link's size until he is the size of the worms. He can then strike their vulnerable heads or tails to damage them. Link's sword will not deal any more damage when he is wearing the Giant's Mask, but it is much easier to quickly approach Twinmold and land a hit while grown. Link is not able to Z-target Twinmold when he is this size, possibly because Tatl, who allows Link to Z-target, does not grow in size with Link. After Link defeats one half of Twinmold, its body explodes, leaving its head embedded in the ground. After both Twinmold halves have been defeated, the battle ends.
Alternatively, Twinmold's weak spots can be harmed by most attacks, though many require Link to approach the head or tail while it is near the ground to be in range. Twinmold can be damaged by firing arrows at one of its weak spots, and the two halves of Twinmold react differently to different elements. The blue Twinmold takes extra damage when struck by Fire Arrows, and can be defeated with only four. It is, however, resistant to Ice Arrows, and when struck by one, it only takes the damage that would be dealt by a normal arrow. The red Twinmold has the opposite reaction, taking extra damage from Ice Arrows, but is resistant to Fire Arrows. Both halves are partially resistant to Light Arrows, taking only half of the extra damage that would usually be dealt, requiring six to be defeated.
Interestingly, if Link strays too far from the center of the desert, he falls through the sand and is transported back to the entrance of the dungeon. He must fight his way back to the boss room and restart the battle from the beginning.
Twinmold is similar in appearance to its in-game iteration; however, only one Twinmold is ever shown or mentioned. After defeating Twinmold, Link meets the last of the Four Giants. The quest to reunite Anju and Kafei composes the remainder of the chapter in which this occurs.
