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 are 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.
