Giant's Mask

The Giant's Mask is one of the masks found in The Legend of Zelda: Majora's Mask. Link gets this mask in Stone Tower Temple after beating the mini-boss Eyegore, and it can only be used in the fight against Twinmold, the major boss of Stone Tower Temple. When equipped, Link becomes a giant. Wearing this mask gradually drains magic. Link can not Z-Target while wearing the mask (this may be because his fairy Tatl does not grow and is used to Z-Target in this game). Because this mask is only able to be used inside Twinmold's arena, some speculate that the mask does not cause Link to grow in size, it instead shrinks the arena and all adversaries inside it. Given the peculiar nature of the Stone Tower Temple, this theory is not so outlandish, however, if one were to use the glitch that allows one to wear the Fierce Deity's Mask by putting it on in Sakon's Hideout, Link will start to grow larger when the mask is equipped, but he will stop once he reaches the ceiling, and he remains in the transformation sequence, requiring a reset.

The only use it has outside of the fight with Twinmold is to trade with the four kids on the moon.
